WASHINGTON - Have you ever heard of macaws that blush, much like humans do at an emotional moment?
Researchers still don't quite understand how it works, but a French team says they have observed the phenomenon multiple times in a group of five captive blue-and-yellow macaws.
They published their findings on Wednesday in the journal PLOS One.
