Gemma Radko and I joined some other assembled birders, including 
Linda Friedland and Jim Swanson at the parking lot to the Nature 
Center (where Baltimore oriole and scarlet tanager were seen). Then 
we embarked for the maintenance yard and stables with Jim. Having 
been there since first light, Jim, Linda, and others had birds we 
missed, including rose-breasted grosbeak, yellow-billed cuckoo, 
black-throated green, etc.

Our highlights:

a blue-headed vireo

  red-eyed vireo (2)

  ruby-throated hummingbird

  catbirds (2)

wood thrushes (2)

a male Balto. oriole

a male scarlet tanager

singing blue-winged warbler (1)
black-and-white warbler (1)
pine warbler (1)
American redstart (1)

indigo bunting (2)

a surprise rusty blackbird at the red horse barn,

and another surprise: a quickly glimpsed male Cape May warbler. If I 
had seen this bird a few weeks later, I'd have felt grateful but 
confident of what was briefly on view. Because it's so early (though 
not impossibly so according to the Yellow Book), it still has me 
shaking my head.
