This morning, I recorded my fourth DICKCISSEL over Etna, NY in the past seven nights. This particular flight call was the best yet.
I have uploaded an audio clip of the Dickcissel from this morning (at 2:47 AM), as well as a spectrogram frame-grab, showing the characteristics of this flight call. These can be accessed by going to these links: Audio: http://www.NortheastBirding.com/111007.024749_DICKCISSEL_Etna_NY.wav Image: http://www.NortheastBirding.com/111007.024749_DICKCISSEL_Etna_NY.jpg Note, the audio file is five seconds in duration, with the flight call occurring at approximately 2 ½ seconds into the clip. This particular call consisted of five distinct note peaks and with a single fainter introductory and closing note, for a total of seven identifiable peaks. I simply didnt expect to detect anything on the recording from last night, given how quiet it was, let alone get something as good as a (another!) Dickcissel flight note. One question I have is about the relative abundance of this species: Is this a particularly good year for them in the Northeast? Did they have a fabulous breeding season in the Midwest? Did a particular weather pattern over the past week or so cause them to migrate up into Canada or up to the Great Lakes, East, then down South from there? Or, are they a more typical night migrant through Upstate/Central New York than we give them credit for? Thanks and good night listening! Sincerely, Chris T-H -- Christopher T.
