Yesterday AM, because I had to go to work for a short time, I birded at 
GSFC.  Hoped to see some early migrants, but struck out except for an E. 
Phoebe.  Somewhat surprised to find a pair of Hooded Mergansers still 
around, and saw about a dozen bluebirds between 7 and 8 AM.  Later, 
around 10 AM, I retraced my path (because I lost a lens cap), and found 
that the bluebirds had been replaced by large numbers of robins. 
Conclusion: Bluebirds get up earlier than robins.

Also saw a half-dozen cowbirds, singing(bubbling?) and waiting anxiously 
for the migrants.

Surprising miss: no White-throated Sparrows.  It seems to me that there 
haven't been as many around my feeders this winter as normal.
