Weather and conditions permitted me to record for migrants last night 
for the first time in about 3 weeks. I was very interested to see what 
would be passing over since I have never been able to record much during 
this part of April. In 2006, I did not really get things figured out 
until early May and in April 2007, the weather was not conducive for 
good recording between April 1 and the last part of the month.

It was a good night for Hermit Thrush movement. I would guesstimate that 
more than 50 passed over between 12 AM and dawn. It was reminiscent of 
good mid to late May night when Gray-cheeked/Swainson's are coming through.

Other birds detected that I can ID include sparrows (Song, Dark-eyed 
Junco, Chipping, and a few Savannah, but no White-throated yet), a 
Black-crowned Night-Heron, a Ring-billed Gull, and a couple dozen 
American Robins.

Also recorded another call I cannot identify and posted it at my 
website: 
http://nightmigrants.com/main/page_species_calls_mystery_call_2.html. 
The background hiss is pretty bad but you can still hear the call 
through it.

Good birding,
