A tiny bird claims victory over a hunting bird of prey which knocked itself out by flying into a window.

The sparrowhawk was pursuing the Northern wheatear over an offshore wind farm site in the North Sea on Thursday.

But the raptor crashed into a window and knocked itself out.

Fresh from it's lucky escape, the wheatear then landed for a moment on the hawk before flying away.

Around 20 minutes later, the bird of prey recovered.
