Hi Geoff, There is a call of Least Bittern on the sound site, Dendroica, that is similar to your recording. It's the last one listed on the Canadian version of the site.
Thanks for raising the question about activity on this list. While I've played an active role on the NFC Facebook group, I do think it is worth the effort to see if this list can be re-activated. I am very engaged in acoustic nocturnal migration monitoring and eager to know who is still doing this and learning from their experience. There has been a recent number of scientific papers in this field and it would be interesting to discuss the implications and explore new ideas. In addition, there is still much to be learned about call identification. Is anyone working on acoustic technology, especially in the area of recording processing (detection, automated identification, classification, and storage)? The bias of eBird toward diurnal data poses time-consuming challenges to entering nocturnal data; can we find a fix for this? These are some my interests, and it would be a pleasure to hear from others.

Hi everyone, I captured the attached recording at 11:39pm on April 24 in southwestern Pennsylvania. I am wondering if this might be a Least Bittern. From what I can find, presumed Least Bittern nocturnal calls seem to be somewhat variable, with some higher pitched and some lower pitched, but all with a similar nasal quality and duration that the attached recording seems to share. This recording is certainly on the lower-pitched end of the spectrum and doesn't completely match any Least Bittern examples I can find, though. Thanks for any input. I'm also posting here out of curiosity as to whether this list is still active. It's been pretty quiet for a long time I don't mean just because it was winter recently. Really nothing posted here last fall or so far this spring. Has this list been more or less replaced by the NFC facebook group?
