I like the idea of a vocal "style" for all birds of the same species. I
think of it as a particular "voice"--for example, you recognize the
voices of people you know, even if they don't always say the same phrases.=
Song sparrows are among the more variable, with each male having a
repertoire of 8 to 10 slightly different songs, so they can be
bewildering. What have others noticed about variability in the calls
and songs of birds? Any vocal signatures uttered by one individual? Is
there an acoustic equivalent of the rare chickadee, crow, or robin with
a few white feathers in its wing? I am always interested in how to
distinguish one individual creature from another, in order to better
study life histories. How about telling trees apart by the wind in
their branches... That last one would be a challenge to record.
As some on this list suggested, I did record the rooster in my backyard
and made him into a truly obnoxious cell phone ring.
