The skylark is a small brown bird, somewhat larger than a sparrow but smaller than a starling. It is streaky brown with a small crest, which can be raised when the bird is excited or alarmed, and a white-sided tail. The wings also have a white rear edge, visible in flight. It is renowned for its display flight, vertically up in the air. Its recent and dramatic population declines make it a Red List species. [RSPB]
The Skylark was a long way from me, ie: it was cropped.
