Put your ID skills to the test with this brief bird sound quiz! (Don’t worry, it’s not a songbird flight call.)
CLICK THIS LINK to hear the sound (20 seconds, 1 MB).
And here’s the spectrogram (an excerpt), just because I think it’s a really cool one:
This was recorded pre-dawn on 10/31/10 in Rye, NY. There is only one species in the recording. Feel free to answer in the comments!
(Oh, and if you are one of the couple of people to whom I’ve shown this recording, don’t answer please
.)
Good luck!

blackbirds?
Sand pipers?
This is neither a blackbird or a sandpiper, unfortunately. Keep trying!
winter wren
American Wigeon? [Great blog!]
Sounds like AMWIs…and a lot of um!
Yep, American Wigeon it is! Interestingly, the microphone location is at least 600-700 yards from the water, but there is a sizeable wigeon flock once you do get down there.
Love the audio bytes and quiz.
