I spent the morning in the field in DC, hitting Hains Pt, Anacostia River
Park, Kenilworth Park and the National Arboretum.  Gary Allport already gave
a report from Hains Pt.  Only thing I can add is that there ended up being 2
Short-billed Dowitchers - a May tick for me and hard-to-find bird in DC.  I
didn't spend much time in Anacostia, just enough to hit the wetlands, which
are very wet (and looking very inviting).  Same goes for Kenilworth Park -
short visit because it was pretty quiet.  The Arboretum was pretty active,
especially since I didn't get there until 10:45 or so.  My day's highlights
are captured below:
