Does anyone have an example of an American Bittern NFC they could attach and
post to the List?
Thanks!

Andrew, et al,
I concur that the single call note is typical in nocturnal migration. I have
probably heard hundreds of single call notes from nocturnal migrants in Cape
May, but the only time I recall hearing multiple-note vocalizations as in

The original recording was from south-central Alabama in the early morning
(~4AM) of October 8, 1989. Andy cut out the dead space between calls. The
actual sequence is over a minute long and one can interpret the bird
approaching and then flying away. This is the only time I've heard a double

Well, at least Minnesota and Alabama are both in the US . . . my

Hi all,
I've recorded Great Bittern night flight calls from time to time in the
Netherlands, Portugal and elsewhere and they were always single notes. One of
the most striking thing about them is the very long gap between calls,
typically 30 seconds to a minute during night flights. When

I live in Battle Ground, Washington which is 20 miles due north of Portland,
Oregon. I've been listening for about 6 years - mostly Swainson's Thrushes
which can number in the thousands on some nights in September. I was
listening from 5:45-7 this morning and had a

Thanks for pulling this together, and thanks Bill, for providing these clips!
Is it most typical for American Bitterns to produce these paired calls during
migration, or do they often just do single isolated notes?
This is very helpful!
Thanks again!

Hi all,
I've certainly heard American Bittern produce isolated notes more
often than not when I've heard them migrating at night, both in the
field and in the lab from recordings; I'd hazard a guess to say that
the single note call is more likely to be encountered . . . but this
is really pure
Andrew, Bill, Michael,
Thanks very much. This collective knowledge is a great resource!
