Native to South America, the blue-gray tanager is a species belonging to which class of animals?

I love the hues of blue, wished they had a picture of the actual bird itself.

I love all the birds singing. The Mockingbirds are aggressive & will steal another birds nest but I ❤️ all the different songs they sing!

Went and looked this up after answering 😍 WOW. What a gorgeous bird!
