I spent a little time this morning doing a "seawatch" in DC, 
waiting for a Neotropic Cormorant to go flying by.  My vantage 
point was Gravelly Point (actually in VA), and I scanned the 
Potomac for all of about a half hour (from 7:00-7:30).  During 
that time, I saw c.15 Double-crested Cormorants, all flying 
downriver, but no signs of anything remotely resembling a 
Neotrop.  However, as I was driving out I saw about 10 more 
headng south but couldn't stop to scope them.  So once again 
my job gets in the way of quality birding time.  I hope to get 
out there again, but no idea when that will be.

Good birding,
