Lol! When we first saw the birds flying around through the trees this morning, we thought they were wood ducks but then they starting making those strange sounds. They sound just like the link Lin added above. Very interesting sounding. Then I zoomed in with my camera and we knew they weren't wood ducks... that led us to finding their name, which is pretty funny because they do sound like they are whistling.
I find it funny how creatures are named. Like when I listen to the Phoebe call, it really sounds like it's saying "Phoebe".
