RE: [nfc-l] Interesting Call

Hi Preston and all, I downloaded the calls you sent. The first one is a “double-up” warbler mostly likely one in the genus Oreothlypis (Nashville, Tennessee, and Orange-crowned). I would lean toward Tennessee for this one due to the nice bend in the spectrogram. When I first looked at the

Hi all, I have been recording in Ithaca NY for last few days. I am finding an interesting pattern in number of calls recorded per hour (between 9.00 pm to 5.30 am). My recordings of the calls peak around 3.00 am in the morning. So I am not sure why that pattern. Whether that is the time when

Recording in central Michigan, my calls were peaking at about 4:00 AM-right by the shores of Lake Huron. My guess is that is when they are flying low and looking to land. I'd have to look at my old data, but I think my inland recorders (not near woodlots) did not see the same peak. Fall and

Another undergraduate at the time from Bates College named Mike Watson did some work for his honors thesis using data from three of my recording units run simultaneously here in Maine all within a few miles of each other. Attached is one figure showing the nightly variation over three October

Sorry all, it appears I was mistake in my earlier statement. I made an excel chart of calls for three nights this week which I have attached below. As you can see, the peak seems to be around 22:00 on all three nights. However, I only listen live until 23:00, and use automatic detectors for the

All, Out here in southwestern Washington State, I have a steady flow of very vocal Swainson's Thrushes flying over every night. Like others on this list serve, I've noted that the number of calls increasing dramatically about an hour or so before dawn. I've often wondered if they are calling

Hi Jeff and all, Thanks for your feed back. It is getting more interesting! I just looked at the data of Sep 21 2015 when I recorded over thousand calls. As Jeff mentioned it peaked around 2 am. As for Swainsons Thrushes, I have been recording very few calls or no calls at all, when some

Hi Jerald and all, Thanks for sharing your monitoring results. I look forward to your next report. As for your strange call, it is indeed strange; very high frequency. I wonder if it is a bird at all. It is almost mouse like. John John Kearney Carleton, Nova Scotia -- NFC-L List Info:
