The most frequent visitors of an avian variety are (in alphabetical order) blue tits, great tits, greenfinches and house sparrows. From time to time we also see chaffinches and goldfinches. I find it interesting to compare the behaviour of the different varieties. The sparrows, which are the largest of the four and by far the greatest in number, are the pushiest. Once one of them gets to the feeder, it stays there stuffing for quite a while, unless another bird - usually another sparrow but occasionally one of the finches - decides that it is its turn and taps the sparrow on the shoulder. Or, more precisely, pecks it on the rump. The greenfinches tend to stick at it as well, but usually for shorter periods of time than the sparrows.
While the sparrows are congregating in the tree, chattering and - occasionally - squabbling, the tits are bouncing around the periphery prior to sneaking through the crowd. They will then wait to dash into the feeder the moment it becomes free, only to grab something and fly off with it. Whatever they have grabbed, seed or not, is then held down on the branch while the bird bites bits off in a very dainty fashion. Once the seed is eaten, the process starts all over again.
