Managed out for the last hour of daylight today. Sun low and bright. Weather very cold, with a hard frost over everything the sun hadn't touched. Walked down by the Cart. Disturbed a Little Grebe which exploded out of the shallows before diving out of sight. Next bird was a Grey Wagtail feeding at the river's edge, followed by a Cormorant flying purposefully downstream. Odd Wrens, Chaffinches and Blue Tits around, plus tens of Jackdaws flying North East to roost. Suddenly, from the mildness of the past few weeks, all has been taken over by the grip of winter.
