Madagascar bird driven to extinction by invasive fish
A bird from the Indian Ocean island of Madagascar called the Alaotra grebe ( Tachybaptus rufolavatus ) has been declared extinct by conservation group BirdLife International. BirdLife contributed to the IUCN Red List of Threatened Species with a major update on the world’s bird species, which was released on Wednesday.
The grebe, previously found only on Lake Alaotra in eastern Madagascar, was driven to extinction in part by the introduction of snakehead murrel, a carnivorous fish, to the area. Fishermen’s modern nylon gillnets, which caught and drowned the birds, also contributed to their demise. The bird was incapable of long flights, so it had a limited range and was vulnerable to attack.
