There were two spring arrivals at Schoolhouse Pond this morning.  I 
spotted one Northern Rough-winged Swallow flying over the pond and 
perching on the wire along the boardwalk.  Also present were two Blue-gray 
Gnatcatchers low in the trees along the trail at the backside of the 
pond.  Other birds present included one Great Egret (also the first of the 
year), Double Crested Cormorant, a pair of Wood Ducks, singing male 
Towhee, and a flyover Kestrel.
