In the spirit of "the more you think you know, the more you have to learn" would anyone please describe the call differentiation between Black and Yellow-billed? I have had both on the sanctuary and banded both species. This year as we listen we had a few obvious Black Billed doing the three note cu-cu-cu and several others that make quite a ruckus and Cu longer. Some are in-between. Re-listened to a bunch of tracks on both and am totally confused. Compounding that was listening to an "obvious" YBCU this morning and when it flew it out it was a Black!
