Hi all --

Finally some favorable weather/winds for migration and the birds cooperated -- 
quite a few birders as well -- one of those days when you wanted to be in 
several places at once, and couldn't be! Clive Harris posted earlier and we 
stayed on and flogged around a bit, so between us all there were 23 species of 
warblers recorded and if anyone heard the LA Waterthrush this am (on territory 
down on Rock Creek) it would be 24! Also, a few other migrants starting to show, 
so things seem finally on track. Unfortunately the leaves are really sprouting 
as well -- so many birds were heard rather than seen -- that is, I guess I saw 
about 4 B-T Greens but we all agreed we heard about 20 in all! 

Sites visited (all very birdy): Picnic area 17/18, Equitation Field, Stable, 
Maintenance Yard, Nature Ctr, and Military Field.
