Our first view was a group of around 500 Starlings flying above the reedbeds on the opposite side of Hedgecourt Lake, my local ‘patch’. More parties of chirruping birds started to fly in above our heads. Soon there were 1000-2000 swarming over the lake, but this was only the beginning.
Suddenly the whole group flew from the lake in the direction of the nearby farm and I was hoping they wouldn’t stay there. Fortunately a separate group started to form where the previous group was and that grew to about 5000.
The group that had gone to the farm returned in ten minutes to join the flock of 5000 and still more separate groups of a few hundred kept on joining. The flock reached 10000 at its climax and I was genuinely stunned and impressed. Unforgettable was the ‘plop, plop’ sound when the flock passed over my head: I was scared to look up!
Suddenly it all ended, all 10000 birds flew down into the reedbeds, how could they all fit? And the question I really want answered, is how they don’t collide with each other?!
I have found out that some believe that when one Starling changes speed or direction, all of the other Starlings respond by following that one Starling almost instantly. Others believe that a Starling copies its seven nearest neighbours. This shows that there isn’t one definite answer, but it would be interesting to find out. Something for the future?
I have also found out that Starlings mainly murmurate like this to avoid predators like Peregrines or Sparrowhawks as these predators find it hard to pick a target in the wreathing mass of birds. They group together to roost in the reedbeds to exchange information about good feeding spots and to keep warm at night.
I’m very lucky to have such an amazing spectacle not far at all from my house!
