I think I have figured out why this bird is called a violet-ear I've been in the hummingbird aviary at the zoo a lot. I've seen this bird pretty much every time. Today was the first time I saw it do this. Another bird was getting a drink or something above it and it got mad. These ear-flaps suddenly flipped up and it chittered up a storm.
“Wherever you are, be there totally. If you find your here and now intolerable and it makes you unhappy, you have three options: remove yourself from the situation, change it, or accept it totally. If you want to take responsibility for your life, you must choose one of those three options, and you must choose now. Then accept the consequences.” -Eckhart Tolle
