Early yesterday (Apr 25) am, before we left for a week-end in CV Co 
(where we have no net access), we had several new arrivals in our yard 
in S. Bowie, along with some others:
Blue-h Vireo  FOY
Red-eye Vireo  FOY
House Wren
Ruby-c Kinglet
Red-br Nuthatch (April 24, prob a migrant)
Wood Thrush  FOY
Scarlet Tanager  FOY
N Parula
Myrtle Warbler - many more than in recent days
White-thr Sparrow   6, still here

The coincidence of all these in so small a space suggests a fall-out 
that morning.
