Hi all,
The topic of night-time roosting is a bit different from migration, but could
potentially prove to be another interesting application of NFC research -- if
birds potentially call, say in the pre-dawn, while exiting roosts. I think this
is one of the least known aspect of bird biology.

Hi everyone,
I've been following this thread with some interest. A couple of anecdotes to
add some more color on this already interesting story!:
1) I had a mob of Fox Sparrows here (central MA) a few winters ago
in February, up to 8 at a time, under my feeder. In the evening, they'd ascend

Ithaca, NY had it's first Killdeer of the year yesterday, so a few birds are
likely moving (but north with the mild weather, or south with the arriving cold
snap??)

Andrew,
It should not be a big surprise to hear a single nocturnal migrant Killdeer at
this time of year in Pennsylvania. Spring migrants begin moving in February,
and "fall" migrants will sometimes move any time in winter if they get pushed
out of northern areas by cold weather or snow.
In my acoustic recordings in Michigan, Killdeer was a very frequent night
caller. Also here in Oregon I hear them regularly at night throughout the
winter. However, they are not rare in either place.
Best,
Caitlin
