See Doug's report of Nashville Warbler from the NYS birding list serve. Makes me wonder about the one seen at the swtchback trail...already gone ?

Adding another individual to this year's (or recent years', even) trend of wintering warblers, we just had an unexpected Nashville Warbler in our small backyard a mile south of Prospect Park. It hung around for a couple of minutes before flying to a neighbor's yard, out of sight.
