Melanistic pelicans

November 29 , 2023 158 days 313 0
  • Two pelicans with aberrant plumage were reportedly spotted at Pallikaranai marshland recently.
  • These pelicans, brownish in colour, were near a flock of spot-billed pelicans but appeared to be isolated from them.
  • The brown pelican is a different species that lives in the southern coasts of the United States and are not migratory.
  • In 2005, two unusual, brightly-coloured pelicans were sighted at Pulicat lake and Nelapattu bird sanctuary.
  • The brown could be melanism – a condition that causes birds to have an excess of dark pigmentation.
