  2. Wow - the red throat on that ant tanager is spectacular...a good example of the handicap principle in action (i.e., if the signal varies in its brightness based on each male's carotenoid-carrying capacity). The interesting thing is that the female's yellow patch is also likely carotenoid-based...I wonder why red was selected for the male and yellow for the female, and not the other way around...or both yellow...or both red. Perhaps it has to do with the circumstances during which the signal is used.
