Saw this Albino bird this morning at Culver Down - Isle of Wight, UK. Size estimated between a Robin and Nightingale. Highly secretive - 9 times out of 10 - flew into the centre of a very think bush and would remain there for some considerable time prior to moving on to next thick bush. Only time it was visible perched in a tree is in picture 4 but that was not for long and I was some distance away. At no time did the bird call. Any ideas as to what type of bird this is?
