Inspired by a recent MDOsprey posting, I ventured to Washington County today for the second time this week.  I wanted to reexamine a warbler I saw on Tuesday (in poor light with only my binoculars) which I figured was one of the Brewster's Warblers reported by Michael Ostrowski, Bill Hubick and Jim Green at Blairs Valley Lake on May 5.  So, this time, I dragged my scope up the hill and was able to confidently identify a BREWSTER'S WARBLER after seeing its white belly and throat and yellow wing bars.  

Blairs Valley Lake held 18 of the 23 warbler species I found today in the county, including a MOURNING WARBLER which was seen very well and singing.   

Besides the warblers and a few shorebirds, I don't think I had anything else particularly remarkable.  I ended up with 107 species.
