This is Chalkie (or perhaps son of Chalkie, as I last saw Chalkie a couple of years ago), a popular resident of this corner of Prospect Park, Reading, UK and a leucistic blackbird. I was out early to avoid the full sun, and so was he.

That is awesome to see (son of) Chalkie after some years again! Would make my day.
It did make my walk, the day is yet young, but maybe to day as well!
Chalkie from 2022, the last time I’ve a photo of them (I’ve also some 2021 photos):
