No, this has nothing to do with Twitter.  It’s about birds.  They go “tweet”.

The American Goldfinch, state bird of Washington, such a gorgeous little creature that likes to flit about my yard.  I had about five or six of them at my feeder this weekend, all in winter plumage.  This spring the males will be bright yellow with a spot of black on top of their heads, which you can see just a hint of in the left image.  The females won’t look much different than the ones in these images.
