OK, Things like this bug the hell out of me so I did a little file
comparisons while the wife was snoring in bed. Here goes'
On the webpage I filtered out Mark's recordings to get rid of the plane and
traffic noises and compared his recordings to my California recordings.
I gotta admit, they are a close call but I'm swaying (As maybe Kevin is?)
that this is a song sparrow showing off his various vocal variations. On th=
e
website I did a couple of spectrograms too. I would call this a song
sparrow.
Hope this helps a little :)

Well, the habitat and behavior is clearly in favor of the Marsh- could
a Bewick be encroaching?
So, there are at least two birds around. Maybe all 3? It is curious
that they avoid calling at the same time, even though they are
separate species.
I have another recording (I am winnowing down about 8 hours of tape at
the moment) where a Meadowlark and a Redwing, it seems, are
-deliberately- calling at the same time, and loudly, as if in some
kind of bragging contest about who can outdo the other. It is funny.
Anyway, so the 'mystery bird' is still something of a mystery. I have
a movie of three seconds of this (careful, it's 10MB) at:
http://aguasonic.com/Movies/Levee50fps.dv
Sorry, the frame rate is a bit high- but you can step through a frame
at a time if you want to catch the detail. QuickTime's 7.0 is still in
Beta, so there are some issues with building and assembling at
different frame rates.
...
In the meantime, it will continue being a 'levee bird' for a while.
Cheers,
Mark
