This is a little more on the part of this thread dealing with song
sparrows. I have recorded in one small marsh area near my home and found
that the song sparrows used a fixed set of song phrases ranging from
extremely brief , up to a second in length. Trills and churrs made up of
very frequent repetitions of mixed frequency transients can last for
more than a second. After I started dissecting the song this way I came
up with 26 (so far) recurring phrases that make up a large number of
complete "songs" in this one very small recording area. I am (of
course) unsure of what all this means beside the obvious conclusion that
their individual syrinxes (syringes) are capable of producing them very
rapidly on demand.
This may be old news, but was not to me so I thought I would pass it on.
