Alaotra Grebe declared extinct

Date: 28/05/2010

Alien fish species and nylon nets forced the extinction of a water bird in Madagascar, a conservation group says. The fragile bird, known as the alaotra grebe, has finally been declared extinct 25 years after the last confirmed sighting, according to BirdLife International. Scientists hesitated to write the bird off too soon since it lived in a remote eastern part that was difficult to survey.An extensive search in 2009 found no sign of the alaotra grebe. BirdLife blamed chick-eating bass fish that were introduced to Lake Alaotra and the use of nylon fishing nets that drown the birds.
