Observaciones de crayonsss

Found hanging limply from thread, on side of an exterior wall. Alive but barely. Has little control over its body, moves little and weakly. Put in this cup for photos, a bubble formed from mouth, visible in second photo. What is that?

This one is immature, not truly juvenile. Been hanging around my neighborhood for a few months, with an adult. This one stays low near houses, poles & trees. It seems strong, flies well, but never soars above a mid-level, even with the adult. It always comes back down. In the Walnut woodland seems not bothered by my presence near it. Seen close up from behind, there is a ring of light color on back of its head, possibly has an injury or developmental problem that affects its depth perception? I've never seen even young ones stay so close to the ground.

Mid-January, 2024- Haven't seen it around for 2 weeks.

Note the "Y" shaped face & ears in blurry photo.

Story: I found a large Fox Squirrel in the street by my house. It was in excellent condition, except for some head trauma, so probably hit by a car. I moved it to my driveway where it would not get squished in the street, thinking a coyote or something would scavenge it. Next day it was still there. Warm day, starting to smell a bit, so I moved it to the hill behind my house, next to the coyote trail.
Morning, 3am, I heard snarling outside in my back yard. Rushed to the window with my camera, turned on the light, to see 2 coyotes, a large and smaller one, standing in ice plant atop the retaining wall. Large one had the huge squirrel hanging from its mouth. Smaller one decided to walk away into darkness. The coyote ate the squirrel: swallowing pieces, looking around furtively for competitors, then repeating until only half the tail was left. Through the window glass I could hear bones crunching. Took 20 minutes to eat that whole squirrel! Seemed unbothered by my yard light, which was enough to get some blurry photos through the window. Then it walked away up the hill into darkness.

Found on walkway, not moving but upright, cool misty day. May be dying. Yesterday skippers and other butterflies were all over my yard in warm sunlight, swirling together in apparent mating frenzies. This one is grayer than others- is it F?

Adult- Behavior:
I heard leaves rustling outside, so rushed out with my camera & flashlight. This opossum was on the wall. It looked directly at me as I watched it hold its tail out behind it stiffly like a stick, waved it slowly side to side, tapping the wall as it moved. Never seen this before! Then it turned, relaxed tail, and walked slowly up hill.
