Not Every Black Bird Is A Blackbird

I was out in the Durham Meadows the other day and came across this female blackbird that had a mouthful of food. She is a blackbird but not a black bird.

This male bobolink is also a blackbird and it is also a black bird but as you can see the back of his head is not black at all. Baltimore Orioles are also backbirds but they are very colorful with the males showing a lot of bright orange.
