Stuck the landing! 10.0 on execution which will combine with a meager 4.0 on difficulty to give a respectable 14. Not the highest score in this owlympic games, but for a competitor of their age (>1) and with an injury, they should be very proud. . . . 🐡🌿 🌎🪶 San Francisco, CA 📸 300mm, F5.6, 1/1600
A brown and tan great horned owl stands on a minor stump that jets out from an oak tree's trunk where a thick branch once grew. The owl's feet are clearly visible on the tree and its left wing is partially raised in the air, the bird having just landed from flight.

A lucky moment in GGP with this Great Horned Owl. I'm not so familiar with bird injuries, but its right eyebrow ain't looking too good. Anyone seen this before? . . . 🐡🌿 🌎🪶 San Francisco, CA 📸 300mm, F5.6, 1/1600
A great horned owl flys towards the camera, its wings paused midway through an upbeat, splayed out with the white and black feathers backlight by the sun. Its yellow eyes gaze behind the camera. The background is a mottled mixture of oak-tree branches and nebulous green leaves.

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

A coyote can be seen sitting underneath an oak tree on a hill covered in short green grass. Immediately behind the coyote is a down tree who's branches are a bright white, establishing a contrast with the vibrant colors in the surrounding picture and emphasizing the brownish red of the coyote's fur.

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
A coyote stands on some grass looking towards the lower left of the picture. About midway up the picture and to the right, a mole can be seen soaring through the air, having just been flung by the coyote.

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

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
A coyote walks parallel to a man and his dog, not more than 10 feet apart. The coyote is looking towards the man and his dog, the man is looking back over his shoulder at the coyote with an uncomfortable look on his face.

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.

Three coyotes can be seen on a hillside that is covered in a matted bush. One coyote bounds atop the hill. Another sits looking around its bend back at the other two. The third can be seen falling down a small crevice in the hillside, splayed out trying to hold on to the bush in vein. Don't worry, the fall was only a meter or so, and it landed on its feet.

Photography can be tough sometimes, hard to line up shots and events unfold quickly. So, you just take what you can get, as in this case, where I attempted to get a lovely picture of an oak tree branch, only to have ppl and coyotes wander into the shot. 🐡🌿🦊 🌎 San Francisco, CA 📸 230mm, F5.6, 1/1000
Two people can be seen in the bottom right corner of the picture frame, huddled together looking off into the distance of the picture, one pointing their finger towards something beyond. In the background, you can see a tangle of oak trees, some green undergrowth, and two coyotes. Though the extended finger isn't pointing at them, the positioning of the coyotes makes it appear in line with the direction of the people's attention.

Peering up around the bend (there's a bathroom on the right). This coyote and its family unit were having a rowdy time on a hillside among some thickets, occasionally hopping up to this perch to watch as runners and dogs passed by on the trail below. 🐡🌿🦊 🌎 San Francisco, CA 📸 300mm, F5.6, 1/2000
A coyote stands peering out from what appears to be a valley between two large bushes. The coyote's ears are perked up and it seems to be looking straight at the camera from afar. The bushes it stands on are chaotic with punctate little leaves and thin branches enveloping the entire right half of the picture. To the left, a similar bush, this one brown, can be seen consuming the left fifth of the picture.
