Ignoring analysis of what it sounds like, I would eliminate Yellow-throated
Warbler as very unlikely since there's only a single small breeding
population of this species in Michigan, well to the southwest of where this
was recorded.
It does sound like a Northern Cardinal chip to me too...

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