Tough to tell from the spectrogram Diane. It shows a ~5 ms section of a steeply
descending call. It appears a higher pitched portion above 8 kHz is chopped
off. Perhaps in the territory of flying squirrel chirps with this one. Can
you make a spectrogram showing the frequencies above 8 kHz or does your system
just use a 16 kHz sampling rate?

p.s. very nice flight occurring tonight across the northeastern sector of the
USA.

Hi night-listeners,
I'm slowly picking my way through a couple of recording sessions from about a
week ago, done from a very quiet wooded cove anchorage on the Eastern Shore of
Maryland.
I have one occurrence of one call that is stumping me. I'm a novice at this, so
would like some expert opinions.
What I'm seeing here is the "lightning bolt" pattern. The Evans and O'Brien CD
talks about Lark Sparrow having a "irregular squiggle in the middle" and having
quite a bit of variation in the placement of the other component (such as
across the top, forming a "T").
Could this be a Lark Sparrow? (A handful were reported from the region on
eBird.) Or is it something really simple and obvious that I'm missing in my
beginner's hunt-and-peck search of the CD?
So far in the rest of the recording I've picked out American Redstart, Northern
Parula, Palm Warbler, Common Yellowthroat, and Chipping Sparrow.
It's fun to be on the really steep part of the learning curve!
