At about 9:30 this morning, we had a Connecticut Warbler at Centennial Lake, Columbia/Ellicott City.  It was just off the east end of the north parking lot (east of the tennis courts), in a lone tree next to a weedy field.  When first seen it was fairly high (about 15 feet or so), but it dropped down into brush in the field, where we lost it.   Jane and I both had good looks: yellow underparts, definite hood (brownish), obvious complete eyering.  I called it a Nashville at first sight (went through the mental checklist: yellow under, olive above, no wingbar, nice hood, eyering...).  Only later did I run through the checklist again, and realize that the complete hood said I was wrong.  I just was thinking "horse" as the zebra galloped by!  I checked with Jane: "That bird had a hood, didn't it?" and she confirmed that she had seen it too.

Dammit!  I still don't have a Nashville for the year!  (But it's my first MD Connecticut!)

Also worth mention--about a dozen chimney swifts, a female Summer Tanager, Palm and Black-throated Green Warblers (among myriads of Yellow-rumps), a probable Lincoln's Sparrow (with lots of Song Sparrows), a Great Egret, a lone fly-by Cackling Goose with two Canada Geese, and a (singing) House Wren.
