I encountered the following NFC while going through data (manual browsing - low call count nights...not bad) from the night of 12-13 May. This bird called once somewhat distant from my listening station in Etna, NY, at approximately 01:52AM.
This is very intriguing to me, because it is noticeably lower in frequency than Indigo Bunting and is slightly descending in frequency over the duration of the call. This is suggestive of Blue Grosbeak, but I am curious to know what others think. This is the first time I have encountered such a low frequency "Indigo Bunting"... As labeled, one file is amplified and filtered, while the other is the original unfiltered clip. Comments? Thoughts? Thanks! Sincerely, Chris T-H -- Christopher T.
