I would be interested to know of any updates on finch night movements as
well. I was surprised to record the flight call of a single American
Goldfinch (AMGO) shortly after midnight on 4/11/08. Have always wondered
if this was a migrant or just a local bird, possibly spooked off its
night time roost. No way to know for sure but interested if anyone else
has detected AMGOs at night prior to the "2hr before sunrise" window
noted in Evans/O'Brien Flight Call CD.

Mr. Evans,
As interest in NFCs grows and new information is gathered, portions of
your Flight Calls CD will naturally become outdated, as this comment
shows with respect to the finch species accounts. I hope to have a
recording setup in place for the spring migration, so I've got a
couple of questions about your CD reference as I begin wading into the
shallow end of the pool:
Is there a revised or remodeled version of Flight Calls in the works?
Are the finches now considered presumed/hypothetical night migrants,
or are there confirmed night flight calling for some of the species?
Are there other major family changes since the CD came out where, like
finches, groups not previously known to call at night have been found
to do so on occasion?
