Context – Spot billed pelicans dying enmasse in Andhra Pradesh
- The spot-billed pelican (Pelecanusphilippensis) or grey pelican is a member of the pelican family.
- It breeds in southern Asia from southern Iran across India east to Indonesia.
- The species is found to breed only in peninsular India, Sri Lanka and in Cambodia.
- In the non-breeding season they are recorded in Nepal, Myanmar, Thailand, Laos and Vietnam.
- It is a bird of large inland and coastal waters, especially large lakes.
- Estimates suggest that increased protection has since enabled a recovery in their numbers and the status of the species was changed from vulnerable to near threatened in the 2007 IUCN Red List.
- Wildlife (Protection) Act, 1972: Schedule IV (Hunting prohibited but the penalty for any violation is less compared to the first two schedules).
- The spot-billed pelican is capable of hunting huge fish from the water bodies and swamps and thus, it is vulnerable to infestation.
Reasons for their death –
- Preliminary inquiry suggests that nematode infestation is the cause for the death of the spot-billed pelicans that preys on nearby water bodies. The nematode parasite is suspected to be transferred through fish and snails in particular, when the birds prey in the aqua ponds.
- The nematode infestation would not spread from one species to another species.
