Hi All, After some inquiries from some of you I asked the USFW and local organizations that were using the house that we are recording from and apparently there are Yellow Rails that breed around that area, so they were not surprised about them being on the recordings. There are several sites north of this area that they are actively monitoring and severl spots to the east a few miles that there are other populations. For those of you tha missed it the recordings were from October 1st. A search several nights on either side of that revealed no other activity, but this is a site we just started so I am not sure if that date means anything as to the timing in that region yet. I also noticed that some of the clips I resampled to get small enough to send sounded bad on my computer at home when I played them, sorry about that, I had to pick short clips to compress and send that were also small enough to be posted to the list, several of the clips I sent bounced. I can try to redo them when I am not so busy if some of you are interested.
I hope some of you got out to listen last night, it was a great night. My daughter and I were up on the roof doing some moonwatching, she really got into it! Are any of you interested in trying to coordinate some kind of formal count tonight as it is forcaseted to be fairly clear and also will be a full moon.
