I found this Black and White Warbler when out walking yesterday morning. There were little bugs everywhere in the air and the trees seemed to be full of birds flitting about, darting here and there among the leaves. It is not a species I see often although the times I have seen it it has been around my home area. Before checking it out in my Sibley's Guide to Birds, I had been thinking maybe it might be a Blackpoll Warbler but it was easily identified as a Black and White when looking at it in the field guide and seeing the white stripe on its crown. The Blackpoll wears a solid black cap. Another feature that identified it as a Black and White was the streaked undertail coverts. Sometimes its quite annoying when a bird turns it back on you when you're trying to get a good picture of it, but in this case it worked out to my advantage.
