Black-crowned night-herons are usually active at night but they’re so busy during the breeding season you might find one awake when the light is good. Then you can see his colors.

Other birds have red eyes too. The red-eyed vireo is obvious — it’s in his name — but the rest require some research.
How many red-eyed birds can you name?
Leave a comment with your answer.
p.s. Here’s a question for the experts (I don’t know the answer): Why do they have red eyes?
