We are in the marginal range of the Black and White Warbler and rarely see them. They act rather like nuthatches, creeping along the bark of trees searching for insects. Wonder if there were bugs on the screen?
Interesting that within a week's time I have come upon two warblers that we don't often see. I also won a drawing from The Thundering Herd (here), and from Vicki Lane (here). Our local bird expert wrote about my Blue-winged Warbler sighting in her weekly newspaper column. I'm feeling pretty lucky. Maybe it's time to buy a lottery ticket. Oh, and since we don't like gambling around here it is the North Carolina Education Lottery since a bit of the money goes to the schools. Did you know they have scratch-offs that cost TWENTY dollars?
