Scrupulously Vegetarian

American goldfinches are scrupulously vegetarian with an almost all seed diet. They don't breed until June or July, waiting until thistle, milkweed, and other seeds are available with which to feed their young.

This is a female goldfinch.  I spent a couple months trying to get a photo of a female, and it seems to be getting easier as I now have more than one female goldfinch photo.
