Woodpigeon Movement

At least 1000 Woodpigeon moving south along the M1 corridor past Higham this morning during the first hour of daylight (yes I forgot to put my clocks back). This is the first large movement of autumn but as in most years will continue for a couple of weeks no doubt. Generally thought to be UK birds moving south, not continentals, and only small numbers continuing over the channel with most remaining in the south and Midlands (they say!)
