This morning it was slow but productive in spite of occasionally windy 
conditions.  There were birds present but you had to work for them!  Not 
much in terms of warbler quantity, but a decent variety (14 species).  I don't 
know what other species other folks may have sen or heard; I observed all 
species below.  Seems like a Catharus thrushes flight occurred last night, they 
were quite numerous.  Also, I don't know how uncommon Bobolink is for DC, 
but there were some in the "Dog Run" area this morning, in the middle of the 
field.  I saw a group of 6 get up, circle once, and leave (heading north); 
followed by a single that got up, called a bunch as it circled.  Then it landed in 
a tree, and after perching quietly a moment, flew back down into the field and 
began calling again.  I had to go then and left.
