American Goldfinch

This little guy isn't looking to build his nest this spring. Goldfinches don't nest until the native thistle goes to seed in late July and August. The down on the thistle makes a nice, soft lining for the nest.

And these tiny gold birds outsmart any cowbirds that may lay eggs in their nests; cowbirds can't survive on thistle.
