Synchronized seed eating

The hoard of fledgies was back today, sitting on the adjacent pear tree waiting their turn on the feeder. There must be at least 8 birds altogether and sometimes waiting just gets too much so they start dive bombing each other off the perches. I didn't manage to get a clear picture of them occupying every port on the feeder but this one amused me when I zoomed in and realised they were mirroring each other's feeding stance.
