Folks,
I've been dabbling in night flight call recording since last spring and
just started following this list, but I had a pretty exciting night in
Cleveland Heights (inner ring suburb on the east side of Cleveland) on
September 13-14, 2010. Between about 22:30 and 06:45, my rooftop
Folks,
I got an odd call that I can't identify on October 2, about 1:30 AM.
Location is Cleveland Heights, Ohio, in a suburban setting. The call was
repeated four times over 5 or 10 minutes. My first reaction was that it

location
Thanks to Benjamin Van Doren and Anne Klingensmith for IDing my call as
(of all things) an American Robin.

I checked with Julie Shieldcastle from Black Swamp Bird Observatory
(south shore of Lake Erie about 30 km east of Toledo). The numbers for
their Navarre banding station were actually above average for the
spring, contrary to my impression that they were low to moderate. Bill

Last night (9/23-24) was fairly active here on the east side of
Cleveland, too. I had about 550 sparrow/warbler frequency calls. The
night before was even more active, with about 900 calls in the upper
frequencies. I'm not checking thrushes at the moment, because it is too

I'm not certain about the ceiling here. At least part of the time that
we were out it looked like there was a thin, low ceiling, but that was

The Cornell folks could probably answer you more definitively, but I
think this is not a bug, but rather a result the way spectrograms are
generated. The spectrogram comes from sampling and analyzing successive
chunks of the waveform, so until enough time has gone by to encompass

thought list members might be interested in this from the May 2016 issue
