A coyote pup, having a roll, roll, roll in z hay . . . 🐡🌿🦊 🌎 Tahoe, CA 📸 300mm, F5.6, 1/1600

Pup butt. After meandering away from the group, this one came bounding back into the grass to start stalking up on its littermates (off-camera in the upper left background). . . . 🐡🌿🦊 🌎 Tahoe, CA 📸 300mm, F5.6, 1/1600

Smiles all around as these pups came tumbling out of the tall grass. . . . 🐡🌿🦊 🌎 Tahoe, CA 📸 300mm, F5.6, 1/1600

In a stroke of dumb luck, I got to watch a gaggle of coyote pups playing in a meadow while passing through Tahoe. It. Was. Magical lol The pics aren't stellar. But, it'll give you a little preview into the unfettered joy of pups playing in a meadow 😍 🐡🌿🦊 🌎 Tahoe, CA 📸 300mm, F5.6, 1/1600

Hey Ya'll, Some of you may know that I work as a scientific ghost writer (😎). If you work in science (🧪🔬🌿) and have about 10 minutes, I could use your help with a little informal survey. Please share it far and wide -- a higher N is always better. Thanks! www.surveymonkey.com/r/SZ23SQR

*Thread* 1/3 Sometimes, feeding coyotes isn't obvious or intended. Here, a person was feeding squirrels. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/250

After watching this, I'm pretty sure that death by coyote is FAR better than death by heron. 🐡🌿🦊 🌎🪶 San Francisco, CA 📸 130mm, F5.6, 1/1600

From out of the shadows, a curious dream, ephemeral in all but memory. (Resharing this one because why not 🤷‍♂️) 🐡🌿🦊 🌎 San Francisco, CA 📸 130mm, F5.6, 1/1600

Watching curiously as people and dogs walk on the trail below. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/250

Another couple shots from 4/20. I was lucky enough to be in a spot where I could see the coyotes emerge from the bushes and then proceed to cross the road one at a time, first wearily, then at speed. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/2000

Sleepy days, what better time to rest among the flowers? 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/160

🧵 On Bold Coyote Behavior: Lots of reports of a coyote in GGP approaching dogs and people. Last week I saw a few ex of this, one shown in this thread. The coyote had seen a dog and its owner nearby. The coyote reversed course to walk towards the pair. 🐡🌿🦊 🌎 San Francisco, CA 📸 120mm, F5.0, 1/2000

Looking back through old pics and found this one, so thought I'd share it on here: A coyote resting among the oaks. 🐡🌿🦊 🌎 San Francisco, CA 📸 120mm, F5.0, 1/400

#InverteFest is here! 24-30 April your local time zone. Share your invertebrate art. Plug your merch & services. Don't forget the hashtag & alt text.

Just close your eyes and feel the warm sun hitting you, a gentle contrast to the cool ocean breeze that begs you to pause for just a moment, to feel it. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/400

While I'm currently working on some gouache, here's an older gouache painting of a grey fox! 🦊 #fox #grayfox #painting #art #gouache #animalart

After being caught, the mole must have put up a little bit of a fight b/c the yote suddenly jolted and sent the mole flying. Otherwise unfazed, the coyote trotted over, picked the mole up again, and wasted little time before downing it. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/2000

Taking a break while also keeping an eye on a pair of dogs walking nearby. This coyote did some hop scotching between green spaces on a busy weekend morning. Always fascinating to see them navigate their way through people and other obstacles. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/2000

Alright, now hold your trophy up and smile for the camera! 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/2000

On the hunt for moles. Got to watch this coyote (viewed through the slats of an electric bike charging station) as it successfully tracked, dug up, and rooted out a mole (more pics to come). 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/2000

A recklessly curious coyote, approaching dogs with what seems like a hint of playfulness. If you see one, it's best to stay at a distance or leave the area. If it comes close, get loud, get big—make it clear people and dogs should not be approached. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/2000

Random request: anybody got recommendations for a good primary care doctor in SF (preferably within Aetna coverage)?

A momentary pause from play as a dog and its owner came jogging through the area. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/1000

Cupid's got me all squirrelly But here's the tea Though it bites like a coyote Your love slays me (Today's a day for very bad poetry, yeah?) 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/800

Movie idea: A Lion King remake in an urban ecosystem, a coming of age tale about betrayal and power struggles among the SF coyote community. Characters include Zazu the Parrot, Timon the squirrel, Pumba the raccoon, Rafiki the elusive Gray Fox, and Scar's band of Ravens as henchmen. 🚗 = wildebeest.

Just a few cherubs playing Lion King in the park. "Brother! Help me!" "...Long live the King 🦁" 🐡🌿🦊 🌎 San Francisco, CA 📸 140mm, F5.0, 1/1600

Leaning into a place of comfort to recharge my sense of creative energy. For me, this means returning to my favorite limited palette to create seascapes, mixing oil paint to create rich gray tones containing hints of blues and earthy browns.
