I have crows nesting in a tree just outside my house. Crows are monogamous, so I see the same pair flying together all the time. Several months ago, they started to look a bit frazzled, they have chicks growing up. So I started giving them bits of food (meats and thawed mice).
They are now bringing me pieces of colored glass :) They also caw if I wave at them.

We see hundreds of crows every morning and dusk. Even close up, I’m hard pressed to distinguish most of them from one another. Perhaps ours in Southern California are more uniform than yours? Or perhaps you’re viewing them with binoculars?
Their nest is about 15 meters from my window, and they often sit on a fence about 5 meters from my window. And because it's always the same pair, you learn how they look after a while.
I probably won't be able to distinguish them in a big flock, but we only have a few crows that regularly fly around my area.
Recently, their chicks also started flying around, so I also keep seeing them. They are slightly smaller, with really nice glossy "baby" feathers.

They are also keeping pigeons and seaguls away.
