Mika, I think the catbird is called that because its cry sounds like a cat. Can't verify that yet as I don't think I've heard it sing. Here's a link you might enjoy:

I also have mockingbirds in my garden that sometimes follow the cat around and chirp sharply. "Cat! Cat! Cat!! " They're very protective of their nests and will fly at humans if you come too close.
Your finches are particularly gorgeous, Philip and aren't they rascals for eating the buds of the flowering cherry! I wonder if there are bugs on the buds or something? I've never seen birds eat flower buds like that.
