“…Examples of leucistic individuals from India includes Jungle Myna Acridotheres fuscus (Nandy 2019), Indian Peafowl Pavo cristatus (Yadav & Arigela 2020), Kalij Pheasant Lophura leucomelanos (Thareja & Thareja 2017), Collared Kingfisher Todiramphus chloris (Adhikary & Mondal 2019), Garganey Anas querquedula (Karuthedathu et al 2014), Indian Spot-billed Duck Anas poecilorhyncha (Raju 2017), House Sparrow Passer domesticus (Sankpal et al 2019), Red-crested Pochard Netta rufina (Mahajan 2016), Brahminy Starling Sturnia pagodarum (Phalke 2020), etc. Leucism is also reported in birds from Bangladesh like in Eurasian Collared Dove Streptopelia decaocto (Islam et al 2020), Western Koel Eudynamys scolopaceus (Rahman 2018) and partial leucism is observed in Common Redshank Tringa totanus (Sultana et al 2020).…”

“…In India, reports on the bird colour aberrations like leucism, melanism and albinism are not that uncommon, examples have been reported for Large Grey Babbler Argya malcolmi (Taher 2020), Rednecked Falcon Falco chicquera (Adaki et al 2020), Spotted Owlet Athene brama (Pande et al 2005), Changeable Hawk-Eagle Nisaetus cirrhatus (Parashar & Sharma 2010), Lesser Sand Plover Charadrius mongolus (Sathiyaselvam 2003), Indian Peafowl Pavo cristatus (Yadav & Arigela 2020), Ashy-crowned Sparrow Lark Eremopterix griseus (Pawashe et al 2006) and many others species of birds. Only a few records exist for colour aberrant birds from Bangladesh (Rahman 2018, Islam et al 2020, Sultana et al 2020.…”

Plumage colouration is important for birds as it helps them in camouflage, mate selection, social signalling and various other physiological and behavioural processes. The most common pigments responsible for colouration are melanins and carotenoids. In a few individuals, colouration is disrupted due to various causes. The most common colour aberrations found in birds are leucism, albinism, melanism, carotenism, schizochroism and dilution whereas xanthochroism is a lesser-known phenomenon. In this article, five records of colour aberrant Coppersmith Barbet Psilopogon haemocephalus are reported. The authors along with the help of citizen scientists observed four individuals with disruptions in plumage colouration from different areas of West Bengal and Assam, India and one from Rajsahi, Bangladesh. Due to the lack of melanins, the birds were mostly yellowish and whitish in colouration with or without some normally coloured feathers on the head and wings. The carotenoid deposition was unaffected in the case of the observed adults and juveniles. These records can be cited as xanthochroistic individuals resulting from leucism. This is the first record of such colour aberration for Coppersmith Barbet from the whole of its distribution range.
