Time to end puppy mills

I am republishing a recent email that came to me.

Puppy Mills are disgraceful. Worse than that they are a scar on the face of mankind.

Yesterday I received an email that came in from the Humane Society Legislative Fund. I am sure many of you also received it.

I am going to republish it. Please help if you can.

Tell the USDA to protect puppies

Dogs suffer horribly in puppy mills. What’s worse is that over the last four years, The U.S. Department of Agriculture, which is charged with monitoring, citing and revoking licenses of these breeding facilities if they sell to pet stores, brokers or online, stopped taking their job of puppy mill enforcement seriously and the agency did not take all the necessary steps to make sure that standards of care are improved to ensure that puppy mill facilities meet the basic needs of happy and healthy dogs.

Enforcement has plummeted at USDA since 2017 and citations for violations are down more than 65%. But we have a new Administration leading the United States Department of Agriculture, one that has already promised that they are going to take animal care seriously. Now is our chance to send a message loud and clear: you must protect dogs and puppies and take puppy mill enforcement seriously, and you must ensure that standards of care are improved in puppy mills to meet the needs of the thousands of dogs living in those facilities.

TAKE ACTION
Please send a brief, polite message to the USDA using the form provided.

The form is available here!

I am going to leave you with a photograph, one of many I am afraid. This one was taken from the Animal Rescue Corps.

Very sad!

What goes around comes around!

Another account of dogs bonding with humans.

Chernobyl is a name that anyone born before, say, 1970 will associate with a terrible nuclear accident in Russia.

As Wikipedia put it:

The Chernobyl disaster was a nuclear accident that occurred on Saturday 26 April 1986, at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. It is considered the worst nuclear disaster in history both in terms of cost and casualties, and is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima Daiichi nuclear disaster in Japan. The initial emergency response, together with later decontamination of the environment, ultimately involved more than 500,000 personnel and cost an estimated 18 billion Soviet rubles—roughly US$68 billion in 2019, adjusted for inflation.

But recently BBC Future spoke of the bond that the guards and the abandoned dogs made.

The guards caring for Chernobyl’s abandoned dogs

The descendants of pets abandoned by those fleeing the Chernobyl disaster are now striking up a curious relationship with humans charged with guarding the contaminated area.

It wasn’t long after he arrived in the irradiated landscape of the Chernobyl Exclusion Zone that Bogdan realised his new job came with some unexpected companions. From his first days as a checkpoint guard in Chernobyl, he has shared the place with a pack of dogs.

Bogdan (not his real name) is now in his second year of working in the zone and has got to know the dogs well. Some have names, some don’t. Some stay nearby, others remain detached – they come and go as they please. Bogdan and the other guards feed them, offer them shelter, and occasionally give them medical care. They bury them when they die.

All the dogs are, in a sense, refugees of the 1986 disaster in which Reactor No. 4 at the Chernobyl Nuclear Power Plant exploded. In the aftermath, tens of thousands of people were evacuated from the Ukrainian city of Pripyat. They were told to leave their pets behind. (Read more about the long-term toll of the Chernobyl disaster.)

Soviet soldiers shot many of the abandoned animals in an effort to prevent the spread of contamination. But, undoubtedly, some of the animals hid and survived. Thirty-five years later, hundreds of stray dogs now roam the 2,600km (1,000 sq mile) Exclusion Zone put in place to restrict human traffic in and out of the area. Nobody knows which of the dogs are directly descended from stranded pets, and which may have wandered into the zone from elsewhere. But they are all dogs of the zone now.

Their lives are perilous. They are at risk from radioactive contamination, wolf attacks, wildfires and starvation, among other threats. The dogs’ average lifespan is just five years, according to the Clean Futures Fund, a non-governmental organisation that monitors and provides care for dogs living within the Exclusion Zone.

That dogs inhabit this ruined place is well known – some of them have even become minor celebrities on social media. Clean Futures Fund co-founder Lucas Hixson, who gave up a research career to look after the animals, offers virtual tours of the Exclusion Zone featuring the dogs.

But less is known about the local workers who interact with these canines on a daily basis.

Jonathon Turnbull, a PhD candidate in geography at the University of Cambridge, realised it might be worth collecting these people’s stories.

“If I wanted to know the dogs,” he says, “I needed to go to the people who know them best – and that was the guards.”

What he discovered is a heart-warming story of the guards’ relationship with the animals they encounter in this abandoned environment – a tale that provides insights into the deep bond between humans and dogs.

The guards sometimes go to the trouble of helping the dogs by pulling out ticks embedded in their skin, or by giving them rabies injections

For instance, the guards have given several of the dogs nicknames. According to Turnbull, there’s Alpha, whose name refers to a type of radiation, and Tarzan, a dog well-known to Chernobyl tourists, who can do tricks on command and who lives near the famous Duga radar installation built by the Soviets. Then there is Sausage – a short, fat dog that likes to warm herself in the winter by lying on heating pipes. These pipes serve one of the buildings used by workers in the Exclusion Zone who are part of ongoing efforts to decommission and decontaminate the ruined power plant.

Access to the Chernobyl Exclusion Zone requires a permit, so guards are tasked with controlling checkpoints on roads in and out of the area. People who dodge these checkpoints to trespass in the Exclusion Zone are known as “stalkers”. Guards report them to the police.

When Turnbull, who lives in Ukraine’s capital Kyiv, started making regular visits to the zone, he met Bogdan, and other checkpoint guards. They were reluctant to talk at first so he had to win them over. Then he offered them to chance to take part in his research, which he says was a “turning point”. His idea was to give the guards disposable cameras and ask them to take pictures of the dogs – not posed portraits but scenes of everyday life. The guards only had one other request – “please, please – bring food for the dogs”. So Turnbull did.

The photos taken by the guards revealed how much they had developed companionships with the wandering dogs of the Exclusion Zone.

Turnbull published some of the resulting images and material from interviews with the guards in a paper in December. More recently, he interviewed one of the study participants again on behalf of BBC Future. The guard in question has asked not to be identified to avoid disciplinary action at work, so we refer to him here by the pseudonym “Bogdan”.

When Bogdan walks around the abandoned streets of the zone to check for stalkers, the dogs happily accompany him, he says. They always appear eager to see whether he, or a passing tourist, might be carrying food. Should a companion dog get distracted or run off to chase an animal, it always eventually returns to Bogdan, he adds.

The loyalty goes both ways. Turnbull says the guards sometimes go to the trouble of helping the dogs by pulling out ticks embedded in their skin, or by giving them rabies injections.

Wolves, dogs and other animals could in theory carry radioactive contamination, or genetic mutations potentially passed on by breeding, to places outside the Exclusion Zone

Monitoring who comes and goes from the Exclusion Zone sometimes makes for a dull occupation. But there are always dogs nearby.

At some checkpoints, the guards have more or less adopted some of the animals. They feed them and give them shelter. But not all are so tame. During his research, one guard told Turnbull, “We can’t inject Arka because she bites.”

Another participant spoke of one dog that was even more difficult to approach. It refuses to be touched at all. “You should just give her a pan [of food] and go. She waits until you leave and then she eats,” the guard explained.

The dogs sometimes bark at strangers on first sight, that’s their nature, says Bogdan. But so long as they don’t feel threatened, they sometimes calm down and wag their tails. Occasionally it even seems as though they’re smiling, he adds.

Generally, visitors to Chernobyl are advised not to touch the dogs, for fear that the animals may be carrying radioactive dust. It’s impossible to know where the dogs roam and some parts of the Exclusion Zone are more contaminated than others.

There is wildlife living in the Chernobyl Exclusion Zone besides dogs. In 2016, Sarah Webster, a US government wildlife biologist who was working at the University of Georgia at the time, and colleagues published a paper in which they revealed how mammals, from wolves to boars and red foxes, had colonised the Exclusion Zone. Camera trap data showed that the animals’ numbers were not noticeably lower in those areas where radioactive contamination is higher.

Animals living in the Exclusion Zone are not necessarily confined there. A later studyby Webster and colleagues, published in 2018, detailed the movements of a wolf tagged with a GPS device. It travelled 369km (229 miles) from its home range in the zone, taking a long arc to the south-east, then north-east again, eventually entering Russia.

Wolves, dogs and other animals could in theory carry radioactive contamination, or genetic mutations potentially passed on by breeding, to places outside the Exclusion Zone.

“We know it’s happening but we don’t understand the extent or the magnitude,” says Webster.

Turnbull says the guards do not generally worry about radiation, though they might occasionally use dosimeters to check a dog over.

It actually seems as though the dogs, through the companionship they offer, end up reassuring those who interact with them regularly, says Greger Larson, an archaeologist who studies animal domestication at the University of Oxford and who was not involved in Turnbull’s research.

“They’re kind of putting themselves in the shoes of the dogs,” he suggests, referring to the guards. “If the dog is fine, that means you’re fine.”

But in truth, this may only be a false sense of security.

“It’s an uncanny environment,” notes Turnbull. “You can’t see the danger. You’re constantly aware that it might be there but everything looks normal.”

Despite the fact that the dogs could pose a risk in terms of radioactivity, guards like Bogdan instead emphasise the benefits of having them around. For example, he claims to know dogs that bark in noticeably different ways depending on what they have spotted in the distance – a human stranger, a vehicle, a wild animal. Because of these helpful warning signals, Bogdan thinks of the dogs as “assistants”.

What’s happening in the Exclusion Zone is an echo of interactions with dogs that are known to have occurred within human civilisations for thousands of years, says Larson.

“We find this for the last 15,000 years or more, this is what people do, they make very close associations with not just dogs but a lot of domestic animals […] to sort of say, ‘this is our attachment to the landscape’,” he explains.

All over the world, there are dogs that inhabit a similar, in-between state – not quite fully domesticated, not quite fully wild. These are the feral dogs that roam cities and industrial areas looking for food, the ones that may become to some extent adopted by people but still wouldn’t be considered pets.

Chernobyl’s dogs also live in this sort of space, on the edge of domestication, but there is a difference argues Webster, who has participated in a separate study of Turnbull’s in the past.

“The Exclusion Zone is very different in that it’s abandoned by humans,” she says. “The only people in that landscape on a day-to-day basis, really, are the guards.” As such, the dogs’ opportunities for befriending humans are very limited.

While the outside world remains fascinated by the dogs, and their story, for many guards the connection runs much deeper. Bogdan says he is often asked why the dogs ought to be allowed to stay in the Exclusion Zone. “They give us joy,” he replies. “For me personally, this is a kind of symbol of the continuation of life in this radioactive, post-apocalyptic world.”

ooOOoo

What is so fascinating is that this interaction between the dogs and the people is an echo of the first interaction between hunter/gatherers and wolves of, perhaps, 25,000 years ago or more. And the guards of today and the dogs, whom Larson calls his assistants, are perfectly bonded.

It just goes to show that ‘what goes around comes around’!

It’s not just us who are social

How about plants!

Yes, a deeply interesting post from The Conversation website shows how plants thrive by communicating and much more.

Now this post doesn’t have a dog within sniffing distance but I still wanted to share it with you.

Plants thrive in a complex world by communicating, sharing resources and transforming their environments

April 14, 2021. 

By Beronda L. Montgomery

Professor of Biochemistry and Molecular Biology & Microbiology and Molecular Genetics; Interim Assistant Vice President of Research & Innovation, Michigan State University.

As a species, humans are wired to collaborate. That’s why lockdowns and remote work have felt difficult for many of us during the COVID-19 pandemic. 

For other living organisms, social distancing comes more naturally. I am a plant scientist and have spent years studying how light cues affect plants, from the very beginning of a plant’s life cycle – the germination of seeds – all the way through to leaf drop or death. In my new book, “Lessons from Plants,” I explore what we can learn from the environmental tuning of plant behaviors. 

One key takeaway is that plants have the ability to develop interdependence, but also to avoid it when being connected could be damaging. Generally, plants are constantly communicating and engaged with other organisms in their ecosystems. But when these ongoing connections threaten to cause more harm than good, plants can exhibit a form of social distancing.

The power of connection and interdependence

When conditions are good, most plants are networkers. The vast majority of plants have fungi that live on or within their roots. Together, the fungi and roots form structures known as mycorrhizae, which resemble a netlike web.

Mycorrhizae increase their host plants’ ability to absorb water and nutrients, such as nitrogen and phosphate, through their roots. In return, the plants share sugars that they produce through photosynthesis with their fungal partners. Thus, the fungi and host plants are powerfully interconnected, and depend on one another to survive and thrive. 

Mycorrhizal connections can link multiple plants in a functioning network. When plants produce more sugars than they need, they can share them via this interconnected root-fungal network. By doing so, they ensure that all plants in the community have access to the energy they need to support their growth.

Put another way, these connections extend beyond a single host plant and its fungal partner. They create communitywide relationships and interdependent networks of plants and fungi. Factors in the external environment, such as the amount of light available for photosynthesis and the composition of soil around the plants, fine-tune the connections in these networks.

Mycorrhizhae also serve as communication channels. Scientists have documented that plants pass defensive chemicals, such as substances that promote resistance against insect pests, to other plants via fungal networks. These connections also allow a plant that has been attacked by aphids or other such pests to signal to neighboring plants to preemptively activate their own defense responses.

Mycorrhizhae are living communities of plant roots and fungi that benefit mutually from their relationship.

When it’s safer to keep your distance

Sharing resources or information that helps other plants ward off danger is a valuable example of the power of connectedness and interdependence in plant ecosystems. Sometimes, however, surviving requires plants to disconnect. 

When environmental cues such as light or nutrients become scarce enough that a host plant can produce enough sugars through photosynthesis to support only its own growth, staying actively interconnected in a larger community network could be dangerous. Under such conditions, the host plant would lose more from sharing limited sugar supplies than it would gain from the network in water and nutrients. 

At times like these, plants can limit mycorrhizal connections and development by restricting how many materials they exchange with their fungal partners and avoiding making new connections. This is a form of physical distancing that protects the plants’ ability to support themselves when they have limited energy supplies so they can survive for the long term. 

When conditions improve, plants can resume sharing with their fungal partners and establish additional connections and interdependence. Once again, they can benefit from sharing resources and information about the ecosystem with their extended plant and fungal communities.

Recognizing kin and collaboration

Social distancing isn’t the only trick plants use to make their way in the world. They also recognize related plants and tune their abilities to share or compete accordingly. When the plants that are interconnected by a fungal network are close genetic relatives, they share more sugars with the fungi in that network than they do when the other plants are more distantly related.

Prioritizing kin may feel highly familiar to us. Humans, like other biological organisms, often actively contribute to help our kin survive. People sometimes speak of this as working to ensure that the “family name” will live on. For plants, supporting relatives is a way to ensure they carry on their genes. 

Plants can also transform aspects of their environment to better support their growth. Sometimes essential nutrients that are present in soil are “locked up” in a form that plants can’t absorb: For example, iron can become bound up with other chemicals in forms very similar to rust. When this happens, plants can excrete compounds from their roots that essentially dissolve these nutrients into a form that the plants can readily use

Plants can transform their environments in this way either individually or collectively. Plant roots can grow in the same direction, in a collaborative process known as swarming that is similar to bee swarms or bird flocks. Such swarming of roots enables the plants to release a lot of chemicals in a particular soil region, which frees up more nutrients for the plants’ use.

Trees use fungal networks to send one another messages – and some species hijack the system to sabotage their rivals.

Better together

Behaviors like mycorrhizal symbiosis, kin recognition and collaborative environmental transformation suggest that overall, plants are better together. By staying in tune with their external environment, plants can determine when working together and fostering interdependence is better than going it alone. 

When I reflect on these tunable connections and interdependence between plants and fungi, I draw constant inspiration – especially during this pandemic year. As we make our way in a constantly changing world, plants offer all kinds of lessons for humans about independence, interdependence and supporting each other.

ooOOoo

I agree with Professor Montgomery. Who would have though it! Plants do indeed offer strong social lessons for us humans. Maybe that explains why trees, especially trees, have such a profound, beautiful appeal to yours truly as well as many other people.

Going to close with a photograph taken of our trees and pond here at home.

They are communicating!

A few of Jean’s paintings

That came via the sale of Jean’s bike.

Yesterday we drove down to Phoenix, Oregon to deliver the Sun Tricycle to the new owners. Daniel and Cherie were a delightful couple, albeit more my age than younger. But they had been through one heck of a disaster. Because last year they were both asked to flee the fires with very little notice and only recently had they found a new home and were still settling in.

Daniel rides his trike and wanted to get one for Cherie. We were delighted with the sale and we hope we all will see each other in the near future.

Anyway, Daniel is quite an artist and Jean mentioned she used to paint before the Parkinson’s tremor made it much more difficult. But Daniel insisted on photographs being taken of a few of Jean’s paintings and sent to them via email.

Here they are.

Is there no end to the smartness of dogs!

A recent video suggests not!

I was idly browsing the BBC News online a couple of days ago and saw this small but wonderful piece.

The dogs helping endangered Tasmanian devils find a mate

A world-first trial in Australia is using detection dogs to help zookeepers identify when Tasmanian devils may be ready to breed.

If the programme is successful, it’s hoped the method could help other endangered species too.

There is a video available but it is nearly an hour long.

Picture Parade Three Hundred and Eighty

This was a real treat!

Jim Ingraham of our local Caveman Camera Club sent out an email last week.

Wednesday, March 17th will be our next education meeting. It will be a light painting field trip with Dale George as the teacher/instructor.

We will meet at Reinhart Volunteer Park (also known as All Sports Park) at 7 pm. When you go into the park take your first left. Just go to the end of the very long parking lot and you are there.

As much as I don’t want to say this, I gotta…Observe social distancing and wear your facial covering. I want all members to attend. I cannot and would not attempt to enforce this, do what you’re going to do, but please be respectful of others.

Bring camera, tripod, remote shutter (not absolutely necessary), fully charged battery, warm clothes, maybe a headlamp to see your camera dials.

Daylight savings time will be in effect so it won’t be getting dark until 7:30 or so.

Let’s get out of the house and have some fun.

Jim Ingraham
Education Coordinator

Now I didn’t have a clue as to what a “light painting field trip” was but Jeannie agreed to come with me so we both turned up on the 17th at 7pm.

This was the area of the park where we all assembled.

In the main a single individual stood in front of us waving a light board in a synchronised manner. It was a flashing board. But there were times when he was joined by a woman and they both swung their own light boards.

Apart from cropping the images a little these photographs are as they were shot!

Talk about incredible!

Lessons

Nothing to do with dogs but everything to do with the future!

An item in The Conversation recently was not only interesting from a scientific point-of-view but also it had real lessons for the way that we humans are interfering with the planet.

As The Conversation introduced the article:

A mile below the surface of the Greenland ice sheet, an ancient Arctic ecosystem is preserved in the frozen soil. How scientists discovered its leaves, twigs and mosses is a story in itself. It starts with a secret military base built into the northern Greenland ice.

Scientists Andrew Christ and Paul Bierman describe the discovery as something of a Rosetta stone for understanding how well the ice sheet stood up to global warming in the past – and how it might respond in the future.

So, for a change, read something that has nothing to do with our furry friends.

In 1963, inside a covert U.S. military base in northern Greenland, a team of scientists began drilling down through the Greenland ice sheet. Piece by piece, they extracted an ice core 4 inches across and nearly a mile long. At the very end, they pulled up something else – 12 feet of frozen soil.

The ice told a story of Earth’s climate history. The frozen soil was examined, set aside and then forgotten.

Half a century later, scientists rediscovered that soil in a Danish freezer. It is now revealing its secrets.

Using lab techniques unimaginable in the 1960s when the core was drilled, we and an international team of fellow scientists were able to show that Greenland’s massive ice sheet had melted to the ground there within the past million years. Radiocarbon dating shows that it would have happened more than 50,000 years ago. It most likely happened during times when the climate was warm and sea level was high, possibly 400,000 years ago.

And there was more. As we explored the soil under a microscope, we were stunned to discover the remnants of a tundra ecosystem – twigs, leaves and moss. We were looking at northern Greenland as it existed the last time the region was ice-free. Our peer-reviewed study was published on March 15 in Proceedings of the National Academy of Sciences.

Paul Bierman, a geomorphologist and geochemist, describes what he and his colleagues found in the soil.

With no ice sheet, sunlight would have warmed the soil enough for tundra vegetation to cover the landscape. The oceans around the globe would have been more than 10 feet higher, and maybe even 20 feet. The land on which Boston, London and Shanghai sit today would have been under the ocean waves.

All of this happened before humans began warming the Earth’s climate. The atmosphere at that time contained far less carbon dioxide than it does today, and it wasn’t rising as quickly. The ice core and the soil below are something of a Rosetta Stone for understanding how durable the Greenland ice sheet has been during past warm periods – and how quickly it might melt again as the climate heats up.

Secret military bases and Danish freezers

The story of the ice core begins during the Cold War with a military mission dubbed Project Iceworm. Starting around 1959, the U.S. Army hauled hundreds of soldiers, heavy equipment and even a nuclear reactor across the ice sheet in northwest Greenland and dug a base of tunnels inside the ice. They called it Camp Century.

It was part of a secret plan to hide nuclear weapons from the Soviets. The public knew it as an Arctic research laboratory. Walter Cronkite even paid a visit and filed a report.

Camp Century didn’t last long. The snow and ice began slowly crushing the buildings inside the tunnels below, forcing the military to abandon it in 1966. During its short life, however, scientists were able to extract the ice core and begin analyzing Greenland’s climate history. As ice builds up year by year, it captures layers of volcanic ash and changes in precipitation over time, and it traps air bubbles that reveal the past composition of the atmosphere.

One of the original scientists, glaciologist Chester Langway, kept the core and soil samples frozen at the University at Buffalo for years, then he shipped them to a Danish archive in the 1990s, where the soil was soon forgotten.

A few years ago, our Danish colleagues found the soil samples in a box of glass cookie jars with faded labels: “Camp Century Sub-Ice.”

A surprise under the microscope

On a hot July day in 2019, two samples of soil arrived at our lab at the University of Vermont frozen solid. We began the painstaking process of splitting the precious few ounces of frozen mud and sand for different analyses.

First, we photographed the layering in the soil before it was lost forever. Then we chiseled off small bits to examine under the microscope. We melted the rest and saved the ancient water.

Then came the biggest surprise. While we were washing the soil, we spotted something floating in the rinse water. Paul grabbed a pipette and some filter paper, Drew grabbed tweezers and turned on the microscope. We were absolutely stunned as we looked down the eyepiece.

Staring back at us were leaves, twigs and mosses. This wasn’t just soil. This was an ancient ecosystem perfectly preserved in Greenland’s natural deep freeze.

Dating million-year-old moss

How old were these plants?

Over the last million years, Earth’s climate was punctuated by relatively short warm periods, typically lasting about 10,000 years, called interglacials, when there was less ice at the poles and sea level was higher. The Greenland ice sheet survived through all of human history during the Holocene, the present interglacial period of the last 12,000 years, and most of the interglacials in the last million years.

But our research shows that at least one of these interglacial periods was warm enough for a long enough period of time to melt large portions of the Greenland ice sheet, allowing a tundra ecosystem to emerge in northwestern Greenland.

We used two techniques to determine the age of the soil and the plants. First, we used clean room chemistry and a particle accelerator to count atoms that form in rocks and sediment when exposed to natural radiation that bombards Earth. Then, a colleague used an ultra-sensitive method for measuring light emitted from grains of sand to determine the last time they were exposed to sunlight.

The million-year time frame is important. Previous work on another ice core, GISP2, extracted from central Greenland in the 1990s, showed that the ice had also been absent there within the last million years, perhaps about 400,000 years ago.

Lessons for a world facing rapid climate change

Losing the Greenland ice sheet would be catastrophic to humanity today. The melted ice would raise sea level by more than 20 feet. That would redraw coastlines worldwide.

About 40% of the global population lives within 60 miles of a coast, and 600 million people live within 30 feet of sea level. If warming continues, ice melt from Greenland and Antarctica will pour more water into the oceans. Communities will be forced to relocate, climate refugees will become more common, and costly infrastructure will be abandoned. Already, sea level rise has amplified flooding from coastal storms, causing hundreds of billions of dollars of damage every year.

The story of Camp Century spans two critical moments in modern history. An Arctic military base built in response to the existential threat of nuclear war inadvertently led us to discover another threat from ice cores – the threat of sea level rise from human-caused climate change. Now, its legacy is helping scientists understand how the Earth responds to a changing climate.

I hope you read it because the way the climate is changing is affecting all of us now and sooner rather than later we have all got to amend our ways. Indeed, when I look at anyone who has potentially thirty or more years of life in them I ponder what their future is going to be like. And, of course, it won’t be a drastic change in thirty years it is already happening now albeit at times difficult to see.

But there is not one scintilla of doubt that we humans are the cause and we humans have to be the solution!

Not just us humans who enjoy a pizza!

A rare sight!

Once again a recent post on The Dodo I felt was worthy of a share.

See what I felt when you read the following:

Wild Coyote Discovers Her Favorite New Dinner

“It was nearly half a pizza.”

A man in California who took up wildlife photography a decade ago had never seen anything quite like what he saw this fall — and he was lucky he had his camera with him.

Every morning, Russell Greaves, of Huntington Beach, California, goes out to the Bolsa Chica Ecological Reserve behind his house to immerse himself in that slice of the natural world. He often sees coyotes, enough that he’s begun to recognize individuals in the area.

“A lot of people here just love the coyotes,” Greaves told The Dodo over the phone, during his morning walk on Tuesday.

Russell Greaves

One morning in October, he saw a familiar wild coyote. It was a mom who had given birth to a litter of pups six months before.

“She had had four pups,” Greaves said. “The pups would come out and play around, while dad went out to hunt. But they’re out on their own now.”

Russell Greaves

It was nice to see the mom again — but there was something different about her. And as she got closer, Greaves couldn’t help but laugh.

Russell Greaves

Somehow, the mother coyote had found a pizza — and she decided to go ahead and take it with her.

“It was nearly half a pizza,” Greaves said. It’s not certain where the coyote managed to find this enormous meal. Greaves said that there are some homeless people who camp out in the woods and perhaps she swiped it from them.

Since her pups had already gone out on their own, she probably wasn’t planning on sharing, Greaves speculated. “I thought, ‘This has got to be for herself.’”

More important than this meme-worthy sight is the balance the residents of the area have struck with the natural world — something sorely lacking in other communities across the country, where coyotes are often brutally hunted in killing contests.

Admittedly, not everyone loves the coyotes quite as much as Greaves does, but many people are fascinated by the wild family living nearby, and people take precautions to ensure a peaceful coexistence. “We tell people to not feed the coyotes. They’re not here to eat human food,” Greaves said. “We tell people who are walking their little dogs to be careful because the coyotes are around.”

“The coyotes come back to the same habitat because they like it here,” Greaves added.

And the coyotes are lucky to have people like Greaves, who love having them there.

Just another wildlife story of endless fascination about the animal kingdom.

What’s a stray dog need? Food and caring!

Another international story of love and caring for our dogs.

This time about homeless or stray dogs and in Peru. Again it was written by Stephen Messenger and was shared on The Dodo website. Again it is about the fundamental goodness that is in a great many humans spanning continents.

Nice Restaurant Owner Prepares A Free Meal For Every Stray Dog Who Visits

“They pay us with their happiness and wagging tails” ❤️

One evening five years ago, an unexpected customer dropped by Gerardo Ortiz’s restaurant, Ajilalo, in Peru. It was a stray dog, a look of hunger in her eyes.

Ortiz could have easily turned the dog away. But he didn’t.

That evening, Ortiz offered the dog a free meal, made just for her.

And thus began an adorable tradition that continues to this day.

Each evening, from then on, the hungry dog came and received a free meal from Ortiz’s restaurant.

But it didn’t take long for word of Ortiz’s kindness and generosity to spread among the community of local stray pups.

More dogs began to arrive with that first visitor— and Ortiz welcomed them all with a meal.

Nowadays, numerous stray dogs arrive to the doors of Ortiz’s restaurant each night. Many are regular “customers,” while others are first-timers — all hoping to fill their bellies thanks to Ortiz’s kindness.

Often, as Ortiz is working, he’ll look up and see a new dog’s face at the front — waiting politely to see if the rumor that free food can found there is true.

It always is.

“For me, they are the best customers,” Ortiz told The Dodo.

And his human customers hardly take that as a slight. Inspired by Ortiz, they often bring food for the visiting dogs as well.

“Thankfully, our clients have reacted well to the dogs,” Ortiz said. “They are affectionate toward them.”

Ultimately, Ortiz’s sweet routine of feeding all the stray dogs who visit does more than keep them from being hungry. It lets them know that their lives matter — a truth that Ortiz is happy to prove to them each and every day.

“They do not pay us with money, but they pay us with their happiness and wagging tails,” Ortiz said. “They are very grateful, and we enjoy giving more than receiving. Since I was a child, I have loved animals. My mother always taught us to help others, both people and animals. She’s my inspiration.”

This is such a wonderful share. Snr Ortiz confirms what we know absolutely. That people who care for animals care for so much more. As Gerardo says: “It lets them know that their lives matter.

I am minded to remember when I first met Jean in December, 2007. Jean was living in San Carlos, Northern Mexico, and had been for many years. Her husband, Ben, had died in 2005.

Jean was rescuing street dogs off the streets of San Carlos and surrounding areas, caring for them, neutering or spaying them, and then finding homes for them mainly in Arizona, USA. Many, many dogs owed their lives to Jean’s love for those dogs. In 2010, after I had gone out to San Carlos with my Pharaoh to live with Jean and her dogs in 2008, we came North to Arizona to find a U.S. home and be married. We came through the Mexican-US border with 16 dogs, all of them with their paperwork in order. I will always recall the American border agent, after I had approached him with all the paperwork, leaning out of his booth and calling to the agent in the next booth: “Hey Jake, there’s a guy here with sixteen dogs!

Jean and I were married in Payson, AZ on the 20th November, 2010.

Very sweet memories and the start of a loving era in our lives.

Loving each other and loving our dogs!

More from the family.

And it involves dogs! Well in a roundabout way!

Back on Monday I spoke of Rik and his company Ahead4Heights.

Rik then sent me another piece of news about a film that he produced at short notice for Brixham Council.

Recent projects being a the Front page of the local rag, a roof inspection in Teignmouth for one of the largest local roofing contractors who is now on board and promising more work.

More interesting was a commission from Brixham Council for a short film showing the natural beauty of an area near Brixham in order to oppose a planning application for 400 houses. I received a call on that Friday telling me they needed the film for the public inquiry the following Tuesday! With only that Sunday looking good for flying I managed to fly, edit and upload the film later that evening so they had it for Monday morning, it was played at the hearing and has become a pivotal part of the evidence and was watched over 600 times over the following few days.

 

The land in question is dog walkers heaven and used by all the local residents.

Here is that front page of the Herald Express.

I regret that it is probably far too small a file to show the details. Never mind!
