Multiple experienced birders saw and heard the Alpha Ridge Park bird. It is
believed to be the same bird that was found by the Big Day trip on adjacent
landfill grounds (not open to the public) the day before. And since they're
being sighted all over the state, I sure hope that this is not a case of
mass delusion. I did try to make an audio recording with my camera (which I
have successfully used to record Sinaloa Wren in Arizonza), but all I got
was Canada Goose honking. Prior to this I've heard and seen them in three
counties, including on the breeding grounds in Finzel Swamp, as well as in
Ohio.
Bob does raise an interesting note of caution, Willows do, indeed,
occassionally utter a call that could be taken for Alder, what USGS refers
to as the Weeo call. There is an excellent discussion of Willow
vocalizations at
http://sbsc.wr.usgs.gov/cprs/research/projects/swwf/wiflvocl_guide_to_surveyors.asp
You'll probably have to use Internet Explorer to make it work, I could not
do so with FireFox.
Another USGS site with Willow vocalizations is at
http://sbsc.wr.usgs.gov/cprs/research/projects/swwf/wiflvocl.asp , but these
appear to lack the narrative featured on the first. Note that both are
threatened SOUTHWESTERN subspecies, but they sound the same to me.
Want to see the comparative wave forms of the WIFL weeo vs. ALFL fee-bee-o?
Go to
http://www.appliedbioacoustics.com/Repertoires/Passeriformes/Tyrannidae/wiflalfl.html
Click on the spectrogram, and you'll get the sound via QuickPlayer (if you
have that on your computer).
To really confuse things, a Wild Bird Unlimited webpage says the CALL of the
WIFL is fitz-bew and the SONG is fee-bee-o (See
http://whatbird.wbu.com/obj/348/behavior/Willow_Flycatcher.aspx)
The Stokes recordings do NOT include the WIFL weeo call. So if you BirdJam
uses those recordings, you can't reference it there.
I certainly got an education today, after dipping on the Bar-tailed Godwit
in NJ (last seen May 17.)
