I live in the southeastern united states, so I'll remind folks that snakes and chipmunks are the more likely predators for baby birds. Now, encouraging folks to co-exist with snakes.. that's a different discussion :-)
I live in a heavily populated area and see crows frequently dining on unsecured trash in parking lots. I've also seen crows when hiking and trail running in the forest. The range for ravens does not expand into my area, though I do travel into raven territory from time to time. I'll try and use what I've learned here to distinguish crows and ravens.
Crows may help other wildlife by eating pests like insects, which could mitigate infectious disease transmission.
