These are recent observations from the North American Animal Tracking Database, an iNaturalist project where naturalists and trackers can share their observations and contribute to research projects.
iNaturalist is an amazing tool for learning about wildlife, sharing your observations, meeting people with similar interests, and contributing to research projects. Click on some of the photos below to open up the full observation on the iNaturalist website.

Owls
The bone-to-bile ratio of this owl pellet is ridiculous skewed towards the bone Found a California Vole skull along with other rodents and a few small bird beaks. Most likely Great Horned but maybe Barn or even something else??

Two (possibly) different items found right next to each other in my front garden this morning. I thought that the lighter coloured one might be an owl pellet, but the darker portion looks like scat, maybe??

Barn owl in pine tree at the intersection by the community center. Multiple owl pellets found underneath the trees.
Owls
Pellets. No species ID possible, but the location supports Eastern Screech, Great Horned and, recently, Barred Owl.
An owl pellet!! First one I’ve found in ages, quite a lot of fur, crushed up bones, and what I suspect are squirrel teeth and claws inside

Snakes
Observed a long, slender fast-moving reddish colored snake emerge from the grass and quickly cross the trail leaving this track. Unfortunately unable to capture photo of the snake due to its speed. Snake was around 4 feet long. Guessing the snake was a Red Coachwhip due to red coloration, length and rapid movement.

Animals
fur or feathers? there is at least one feather evident in these remains, visible in the second and third photos. no idea if is part of the remains or became attached to them post mortem. anomolous animal remains found on the sidewalk below a tree in the 12th and Harrison Sts, Downtown Oakland, CA, black-crowned night heron and snowy egret urban rookery. first photo, how it was found, in situ. second photo, underside of the remains. dead flies underneath, embedded in the remains.
Animals
fur or feathers? looks sort of like juvenile black-crowned night heron remains, but run over hundreds of times and recognizable traces near-obliterated. something at the right side of the third photo that looks like heron leg or snakeskin! found in the middle of the street at the 12th and Harrison Sts, Downtown Oakland, CA, black-crowned night heron and snowy egret urban rookery.
