" When the male arrives on the breeding grounds, he perches at the tops of tall trees and sings to defend his territory and attract a mate. In the molt following the breeding season, the male retains his black wings and tail, but his plumage becomes a misture of green, yellow, and red patches, later becoming dull green and yellow, appearing similar to the female."
I guess I got him at the right time.
The book I used is Birds of North America by Fred Alsop
