The Bird Mystery is a unique phenomenon that occurs at Jatinga, a village on a ridge, is located in Dima Hasao District, Assam State in India, between September and November each year. During these late monsoon months, several migratory and local birds commit mass suicide at the village. Just after sunset, between 7 and 10 pm, hundreds of birds descend from the sky, plummeting to their deaths by crashing into buildings and trees. Since birds aren't known to be suicidal, the phenomenon has baffled villagers, visitors and scientists alike.
