Cocoa Thrush (Turdus fumigatus) with partial leucism seen at the Royal Botanical Gardens on Sunday 8th January 2023.
Leucism is an abnormal condition of reduced pigmentation affecting various animals (such as birds, mammals, and reptiles) that is marked by overall pale color or patches of reduced coloring and is caused by a genetic mutation which inhibits melanin and other pigments from being deposited in feathers, hair, or skin.
This condition to my mind makes this bird a bit more attractive.
