I don't know about jays, but I once read that someone at the U of W determined through experiments with people wearing masks?that crows can recognize human faces.

Subject: [Tweeters] Corvid info please

I have a few questions about corvids in general and some specific on Jays (both Stellar and Scrub).

How good are their vision and hearing?

Secondly, crows seem not to mind the jays (well, they are much bigger and more aggressive - I notice that the Stellars get intimidated if more than a few crows and while there will just watch and not try to get peanuts, etc.) and? jays are in the crows territory.? However, we have colonies of Stellar and Scrub Jays here on Queen Anne for years and they will not go into each others territory.? They'll go within 1-2 blocks and that's it.? Any one else notice this or have an opinion on why?? The Stellars seem to have a larger territory; however, there seems to be more Stellars. Could that be it?

I've been feeding the Stellars and crows for several months and they know me by voice.? However, walking through the scrub jay territory yesterday - they also knew my voice (I live about 5-7 blocks from them) and came immediately for peanuts (and followed by the crows).? Anyone had any experience with a different crovid species knowing them when they shouldn't (I rarely walk in that area - and had been 3-4 years since I'd seen one as so rarely in that area).? Seems like the crows in Wallingford know me too, but not lower QA or other places I'm go to occasionally.? Don't know why the Wallingford crows know me; however, I've had crows in 2 different places (about 1 mile or more distant from each other) in Wallingford seem to know who I am.
