Aberrations

James took this photo of, dare I say it, a white throated Robin yesterday at Swanwick - thanks to Ian for the location. It reminded me of the leucistic Coal Tit which is still at Carsington at the Lane End feeder having been first seen in October last year according to Roger. The Coal Tit was photographed by Ken.
Plumage aberrations in birds do not generally create a lot of interest although I think a few people have been to see the Coal Tit. 
Collecting aberrations used to be all the rage for butterfly collectors and still generates quite a bit of interest amongst entomologists.
I have struggled to see anything today but 200+ Brambling on Screetham Lane is a decent flock.
