Benjamin et al., 


This one also sounds fine for Barn Owl in terms of tone, pattern, etc., and not 
right for Great Horned. But odd to hear it doubled like that. They usually give 
single, well spaced notes.

Hi Ethan, All, 


I recorded this possible Barn Owl on May 1 of last year. No Barn Owls occur in 
the area in which it was recorded (so presumably a migrant), but it does sound 
very good for this species in my opinion and definitely has a similar rising 
inflection. Great Horned is also a possibility and nests nearby but I think 
Barn fits this call better (more of a "white noise" feel and hissing quality). 
Thoughts welcome on this one.

How frequently do Barn Owls make a call that is this relatively pure-toned?

I was thinking Saw-whet Owl (which are migrating big time now in northeastern 
U.S.). I've never heard a Barn Owl do quite that call, but certainly 
possible

[nfc-l] Bicknell's NFC

2012-10-02 Thread Jeff Lemons 
On Sunday morning I heard what I believe was a BIcknell's Thrush call and was 
wondering how reliable it was to call a Bicknell's from nfc only.

Myself and Jeff Lewis were on the 6am ferry across the Currituck Sound in 
coastal NC.  A small ferry from Currituck, NC to Knott's Island/Mackay Island.  
There was only a light wind and the engine noise was not bad.  Not ideal 
listening conditions, but the birds we heard, we heard clearly.

There were 5 nfc's on the ride that were from low flying birds.  There were 2 
Swainson's, one Bicknell's, one Gray-cheeked, and one non thrush that I 
couldn't ID.

When we heard the Bicknell's we both immediately called Bicknell's.  It was a 
much longer call than Swainson's or Veery.  It was much higher pitched than 
Gray-cheeked and had almost a whistle quality rather than the burry/raspy 
quality that I hear in Gray-cheeked.  It was loudest/sharpest near the 
beginning and then trailed off gradually.  The higher frequency and the 
clearness of the call really stood out to both of us.  It only called once and 
of course we didn't see the bird for visual ID since it was dark.  The 
Gray-cheeked call was after the Bicknell's and made for a good comparison 
giving a lower pitched raspy call.

Does Gray-cheeked ever make a more high pitched cleaner call that could be 
mistaken for Bicknell's?  I am doing an NC Big Year and am not sure how to 
handle this bird.  

Thanks,
Jeff Lemons
Charlotte, NC
