Can anyone shed light on the reason for the behaviour of two blue tits observed today?
They flew out of a hedge together and tussled around in the air, spinning and swirling for a minute before flying into the grass at speed to land together in a motionless heap. We watched through binoculars but could see no movement at all.
After about 10 minutes we stepped outside to take a closer look. They were still to the spot on the grass, one bird was on top of the other, the uppermost bird appeared to be limp and lifeless, and yet seemed to have the other bird pinned down.
After watching for a minute, a noise disturbed them and in an instant they flew up and off at speed together,
It was all most peculiar, but what would be the reason?
