观察细节
A mixed flock of approximately 300 birds landed in two eucalypt trees, continuously chattering. I got views with binos from 30m. Another 100 or so birds arrived, then all departed in a large tight flock. It was all quite frantic. They circled around directly overhead for a minute or two at 20m then started gaining altitude, still circling, though the flock eventually spread out a bit. After several minutes and still overhead circling they could no longer be seen with binos. About 10% of the birds were Masked Woodswallows.
