Calling all birders!
We have a mystery bird at the Edit Barn. It is shy and wily, but noisy. We haven't gotten close enough to even see how big it is. At sunset, it begins to call. About every 10 seconds or so, it gives a shriek. Sort of a "wheek!" But sometimes it changes. "Whar. Whrack. Wheet? Wheek!"
Imagine that, every 10 seconds, all night long. All. Night. Long. The bird seems to kind of circulate on the property, sticking to the high trees. It stops right around sunrise.
It sounds like a large bird. There's a lot of power behind it. It sounds like a raptor. But what non-owl calls all night long?
