Which Cackler?

Prompted by the last post on the subject, Minimal Interest, Joan Chaplin sent me these images of a Cackling Goose at Foxholes Fisheries, Crick from 23rd April 2012.

This bird arrived with visiting Canada Geese and was subsequently thought to be of the race minima. In common with the Daventry individual it shows a number of features which are inconsistent with that race: too large, too long-necked, the body is more elongated, the head not square enough and the bill – though small, is the wrong shape, i.e. too long.

All features are, however, spot-on for taverneri, Taverner’s Cackling Goose, right down to the thin, broken throat line which almost divides the two white cheek patches.

Note how the bird’s size and shape appear to vary with pose and camera angle! While this western USA bird was surely an escape, Taverner’s has been recorded in Ireland in the recent past.
