It had to happen one day - sign of the times.

From Birdguides:
Interesting winter reports included several Swallows in the continuing
exceptionally mild weather.
Two overwintering birds were reported from Pembroke and others were seen at
West Bexington (Dorset) and
Budleigh Salterton (Devon).

In our garden in S.Cambs, the cat caught two half grown nestling Robins as
early as 23 January.
