On one of these I went upstairs to see what he was doing and he came to the window where I stood and hammered the glass hard about 6 inches from my belt buckle. R not calling. During all of this 5 hour period he did not call his mate once and boomed on only one occasion, the purpose seeming to be to announce his immediate intention of flying up to the roof.
