Last month whilst staying with my father I hid behind the Venetian blinds and poked my camera lens through to see what was occurring at the bird feeders. There were several phases of activity when several birds arrived at the same time.
This very beautiful long-tailed tit, timid and nervous, only really managed to tuck in once the other birds had flown away.
Then a noisy chattering of starlings (well six or seven) turned up to muscle their way in.
After initially flying away the long-tailed tit eventually plucked up enough courage to fly back and hang onto the feeder and wait for his turn again. He obviously knew his place in the pecking order.
Not all the birds were interested in the fat ball. The greenfinches were happy to peck away at the sunflower seeds. Much to my amusement I did see the starlings make an attempt at landing on the perches, but they were too big, and, after unsuccessfully flapping around and wasting energy, they gave up and returned to the fat ball.
