I have been asked this question before. My first thoughts were that maybe a=
n omnidirectional mic on a PZM plate might be better since the chance of pi=
cking up a single migrant flying by seems difficult. Then someone on a Face=
book group said that since the birds are flying high up, that they really n=
eeded the gain and isolation from surrounding sounds that a parabola gives.=
If that is the case, the Pro Mono would work well, but it leads to another=
issue, the need for arrays of parabolic microphones in spaced line. I am n=
ot an expert in nocturnal migrant research, so you might want to collaborat=
e with other researchers to find out what worked out for them. I do believe=
, I read Cornell University has done extensive nocturnal migratory research=
and developed computer programs to automatically identify and count migran=
ts. I would also talk with Russ, who replied here, as to his experiences. M=
aybe some others here have some insight as well.=0D

I was wondering Bruce (or, indeed, anybody else with relevant experience) =
which of your products you would recommend for recording over-flying noctur=
nal migrants, where the actual location of the bird in relation to the micr=
ophone is unknown. Is your most directional microphone actually less-suited=
to this kind of work? Or is the gain increase so significant that it remai=
ns the best option?=0D
