John-
Wow! I've heard some flybys, but that one's amazing! Find any feathers on y=
our rig? It really makes me re-think how aerodynamically sound some birds a=
re. If they generate that much wind noise, they must also be fighting subst=
antial drag.
Your suggestion of the duck sounds most plausible- after ruling out RF inte=
rference, I was thinking a predator flying away with a small distressed mea=
l-to-go in its talons, but having heard it a few hundred more times (well, =
OK- 20 or so), I started remembering hearing similar in-flight vocalization=
s from waterfowl.
Loons seem to let their wings do the talking: http://tinyurl.com/2fsyaf5
Thanks for the ID insight and especially for the merganser- incredible!
