Hitchcock's Rooks

Rooks gathering at dusk this evening, in an old, half-dead sycamore in the field "next door".

An echo of the behaviour at (a rather earlier) dusk in winter, but then in much greater numbers.

K7, Sigma 600mm F8 mirror, tripod, shutter release 3 sec. delay.

C&C welcome, as usual.

Coker.
