Yesterday's got a leucistic Jungle Babbler @ Ayodhya #IndiAves
In leucistic birds, affected plumage lacks melanin pigment due to the cells responsible for melanin production being absent. #birdwatching #nature #BirdsSeenIn2021 #BBCWildlifePOTD @Avibase @ThePhotoHour

This results in a white feathers, unless the normal plumage colour also comprises carotenoids (e.g. yellows), which remain unaffected by the condition. Although leucism is inherited, the extent and positioning of the white colouration

can vary between adults and their young, and can also skip generations if leucistic genes are recessive.
The reduction of pigment in leucistic birds causes feathers to weaken and be more prone to wear.
