I leave a couple of monitor boxes around various habitats for the
spring early choruses and the hours of recordings are then put into a
database and species are then noted.
I use a couple of song-meters tied to various trees.

Here is a variation of a spotted towhee I found on one of the
recordings, it kind of finishes with an up-note. At the end of the
file is the normal trill for reference.
The first part of the recording is contaminated by aircraft (04:15 in
the bloody morning)
The recording is meant for monitoring purposes not quality of sound.
I also found a pre-dawn song of the "Olive-sided flycatcher" little
bugger started calling at 04:10, amazing.
You can find the recording here.
