Re: [nfc-l] YT or OC warbler?

[Chris Tessaglia-Hymes]

This call appears to be too short in duration (~22ms) for nearly all of 
the "short upsweep" warblers (sans Black-throated Blue) and seems to be 
lacking the "double-banded" feature of several of these types. This 
flight call also appears to start potentially as low as around 5.1 kHz, 
which is below the starting frequency of several of these warblers. 
Granted, there's bound to be all kinds of possible variation. In looking 
at the structure of this call note, it appears very similar to that of a 
Northern Cardinal. Is it possible that this was a slightly distant chip 
note from an evening-settling Northern Cardinal, or perhaps one 
disturbed from its roost? Maybe I'm way off here, but is this a possibility?

Sincerely,
Chris T-H

Hi All, 
This call was recorded at Tawas Point, MI. just after sunset.  Any suggested ID's?  I'm thinking either Orange crowned warbler or yellow throated warbler.

Thanks!
