|Prothonotary Warbler (Wisconsin DNR image)|
As I watched it, it occurred to me that the bright yellow male Goldfinches have black caps, and this bird did not. I tried to pay attention to details of color, and ID came from the trusty bird guide.
We are apparently in the northern-most breeding region for this warbler. They like floodplains, so perhaps the creek that runs through our backyard qualifies (the mortgage lender sure thought so... but that is another story). Being the geeky-dork that I am, I emailed the state biologist about spotting the bird. I'm hoping two things: 1) that I can learn what to put out for these birds to eat, and 2) that he even cares... Then again, he's running a nesting program for this warbler, so maybe only geek, not so much dork.
