> I get an eerie feeling sometimes watching Western scrub jays, gray jays, and Steller's jays and how complex their behavior can seem.

All members of the family Corvidae (along with crows and ravens), and all quite intelligent -- so intelligent that the meant-to-be-critical phrase "bird-brain" seems too wide of the mark.

I just discovered that Corvids pass the mirror test. I've always known them to be very smart, but this is a new twist.
