I am officially now up and running, recording & analyzing the nocturnal flight calls over my house!
The purpose of this post is to get you guys to all do this so we can add another subcontest to the blog for all species recorded by one's mic (translation: b/c it is the coolest thing ever but you will not recognize this fact until it is up and running at your house, and I am your friend). Plus, this will REALLY help you out Sean as you move to urban Illinois and have few passerines by day, and Curtis it should greatly increase your list as well, since much of what migrates over will never stop in your yards. Here is my final setup:
Last night I began looking through calls for the first time and I am just now starting to assign them to species or categories. All of these calls were recorded during the first half of the night on 11/12 Sep 2009, I exported about 20-25 that were legible from that period. These are the ones I feel most confident about, but there are many more mystery calls. (In each case the y axis goes from 0-10 kHz, but I didn't take the time to create axes. The x axis varies but typically the full screen shows about 0.3-0.6 seconds):
Tennessee Warbler (possibly but less likely Nashville):
American Redstart (possibly but less likely Ovenbird)
American Redstart (possibly but less likely Ovenbird)Grasshopper Sparrow? Dave, need some help on this one:
