There was a lot of activity just outside my door this morning, but relatively 
little elsewhere.   I'm not complaining.   Yesterday's Orange-crowned Warbler 
was re-found by Pat Scheid in the afternoon, but could not be relocated 
today, nor could the Prothonotary.   They morphed into a flock of Myrtles.

Blue-headed Vireo 2
Yellow-throated Vireo 1
Red-eyed Vireo 1
Veery 1
Northern Parula 1
Yellow Warbler 1
Chestnut-sided Warbler 2
Black-throated Blue Warbler 2
Yellow-rumped Warbler 30
Black-throated Green Warbler 3
Blackburnian Warbler 1
Black-and-white Warbler 2
American Redstart 1
Scarlet Tanager 1
Baltimore Oriole 2

The warblers were all heard only, except for the Chestnut-sided and 
Yellow-rumped.   Morris Arboretum in Phila. reports foliage about 10 days early this 
year, hence the high frustration index.
