Observation details

NFC 4. The calls are distant with 4 notes audible in the recording. The spectrogram of the last note is an excellent match to the spectrogram of the flight call of the American Oystercatcher as illustrated in the account by Erica Nol and Robert Humphrey in the Birds of North America Online. It is also similar in spectrographic analysis to the various notes of American Oystercatcher as illustrated in the work of Pieplow in the Peterson Guide to Bird Sounds and recordings in NatureInstruct. In particular the last note has a duration of a quarter of a second with a frequency between 2.4 to 4.2 kHz. These measurements and the double banded crest shape is totally consistent with the spectrogram of the flight call of Nol and Humphrey. The "whew" call on www.petersonbirdsounds.com most resembles this flight call.
