Flipping through Pieplow it looks to me that Nelson's Sparrow might be a
match (relatively monotone, several overtones, with 2nd partial the
loudest). What seems wrong though is that your recoded call lasts 0.28
seconds, which seems long (too long?) for many sparrows.

Hi All,

It looks like a good candidate for Seaside Sparrow.

Hello NFCers,

 

I recorded the attached flight call on April 27, 2017 in north Mississippi.  It 
seems long and relatively high and may be a fit for an Ammodramus spp.  Doesn’t 
seem to fit the usual single-banded Grasshopper sparrows I have found and 
doesn’t descend like the Le Conte’s.  Am I way off on something?  

 

Hope all is well,

Re: [nfc-l] NFC ID Help, Maryland Eastern Shore

Pretty sure it’s not a bird sound.  

Good that you got the sampling rate switched. Also, I think it would help you 
in your ID process to make the spectrograms with higher resolution.

Looks like a north wind and good migration potential for you tonight if you are 
still in MD.

Hi Bill, 

I inadvertently had the setting on 16 kHz, messing around with some i-mics and 
recording apps, so I missed checking the default rate and figured it was all 
set from last time. So this one was recorded at 16 kHz. (I've now switched to 
22,050 and hope it sticks in the preference settings.)

Here's one last spectrogram of the call, with different X-Y ranges displayed, 
but nothing above 8k, sorry.

Thanks,

Diana

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

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!
