Migration, finally - 18 warbler species + Summer Tanager

After an unprecedented contrarian weather system substantially shut down migration for the best part of the last two weeks, the trend reversed itself and Friday saw good numbers in the park.  Not legendary numbers, but the sort of migration that was in start contrast to all the previous days in May.

I saw, in the first 25 yards in Strawberry Fields, more warblers than I had seen in total during the last two weeks (i.e. since the last significant migration in late April).  While there were some underrepresented species (thrushes, flycatchers) it was strong day for FOY birds: Nashville, Bay-breasted, Blackpoll, Canada, Magnolia Warblers; Summer Tanager (a nice male); Red-eyed Vireo; Wood Thrush; (Swainson's Thrush also heard).  Other good birds included multiple Scarlet Tanagers, Worm-eating Warbler, two Cape May Warblers.  I conspired to miss any Blackburnian Warblers but there were significant numbers of most of the commoner warblers in the park for May.

There's also signs of delayed migration effects: multiple singing (i.e. male) Blue-headed Vireos - and while May 10th is certainly not my late date for them, the ratio of Blue-headed to Red-eyed was anomalous.  The absence of Veeries was conspicuous.  Still, with continuing favorable winds tomorrow (Saturday) may yet change the species mix.
