In reply to Flinticus:
Defo a Jay - you see pictures of them pink + bright blue flash - should be easy to spot - but no, they're actually amazingly camouflaged. Also they tend to be much more secretive than their nearest UK cousins - magpies. Call is a a very harsh sort of rasp - quite easy to identify once you know what it is.
Oh, and get a jay to eat out of your hand and we will all be gobsmacked - likely to be orders of magnitude more difficult than your latest crow mate.
