They are territorial, so you can sometimes recognize them based on location and number when there's nothing else distinguishable about them. There used to be two of them that would claim my front yard as their territory and they'd claim first access to any food that was put out and drive off competitors. They increased in number though and I could tell they had some kids because they did the whole squawking fledgling act where they scream to be fed constantly. So now there are more members of the family that dominate the area.

Different sets will follow me around in different parts of the neighborhood, again reflecting the territorial aspect. There's one couple a few blocks from my house that is highly distinguishable because one of the birds has a wonky wing. My neighbor named that was Twitch and its mate is Shogun.

Here's a post featuring them and one of their fledglings: https://lemmy.ml/post/17566746

There's a crow at my work who hides his treats in a particular patch of grass and so I call him Stash. I've seen him drive off other crows who get near his stashes.
