[Tweeters] Fwd: Avian AI of the evolutionary sort

[Robert O'Brien]

I fotgot that Tweeters doesn't accept photos so this was originally
rejected.  Here is the url which might work:

See attached photo but I'll explain.  An egg-parasitic bird has evolved
such extreme egg mimicry that it can lay an egg that is 'indistinguishable'
from the host's eggs, even though the host's eggs vary among individual
birds of the host species.  BUT, the host is 'so smart' that it can still
reject virtually all of the imposters.  But not all, so the parasite
persists.  Equally amazing is that scientists have figured this all out.
Each group of 3 eggs is from a different host's nest;  that is, two
different host birds and two different nest-parasites.

PS  I hope I got this all straight myself.
