Decided to try a slog into Northwest Branch Park again today, to see what was still around. We wore wellies and left the dogs at home. We assumed, rather incorrectly, that the rain and overcast would have kept most of the migrants on the deck. However, there had been a changeover since Wednesday -- most of the Golden-Crowned Kinglets, Black-throated Blue Warblers and most of the remaining warblers had vanished, but there were many more sparrows and some newly arrived Winter Wrens. We did relocate one of Wednesday's "goodies" in about the same spot -- the adult female Connecticut Warbler, which again gave us only a short time of enjoyment before mysteriously vanishing into the undergrowth. Counts: Black-throated Blue (~12, mostly female), Magnolia (2), "Myrtle" (8), Common Yellowthroat (~8), Connecticut Warbler (1), Winter Wren (6), Brown Throasher (1), White-throated Sparrow (50), Swamp Sparrow (2), Golden-crowned Kinglet (6), Ruby-crowned Kinglet (3), Wood Duck (30), Barred Owl (1), Great Blue Heron (1).
