I had a momentary double take realising quickly that despite the time of year and location it wasn't Rose-coloured Starling but a leucistic Common Starling. I'd often wondered about the accuracy and correct use of the terms 'leucistic' and 'partial albinism', a quick google and the Cornell Lab have it all sorted.
Finally, this bird was such a poseur and very confiding walking around to within a few feet. It's an adult and not one of this year's young. There was a second adult nearby with a single white tail feather, I wonder if they are related, perhaps siblings? travelling in a family group that has amalgamated with other family groups. Anyone else seen this individual around?
