Podrobnosti k pozorování
Huge roost in trees in front of watchtower. Birds tightly packed in various groups of trees across a 50 degree view, c1km distant. On a few occasions, most took to the sky in 2 or 3 large flocks, and dispersed back into the trees after a few minutes. Very difficult to estimate numbers. I tried a few times in typically very rough blocks of 1000, and generally aborted each attempt! c20,000 seems reasonable though. c0815 the sun finally broke through, and prompted much more activity with many birds thermalling overhead.
