It is believed that in a small town in North Eastern part of India (Jatinga) birds commit suicide in a particular 1.5 km long and around 200 meters wide strip of field area.
These birds are not suicidal since their behavior may be attributed to heavy rains and floods and submergence of their natural habitat in the surrounding areas. Also the local villagers light torches which attract the birds migrating at night. They then clobber them to death with bamboo poles and eat them!
