To the villagers, the annual arrival of black-neck cranes is an event that holds great significance. As well as heralding the beginning of winter, some believe these endangered birds to be the reincarnation of two deities who are said to be protectors of this beautiful valley.

When both arriving and leaving, these graceful birds will circle the Gangtey Goempa three times. To the locals, this represents the honoring of the three sacred jewels of Buddhism and the request and gratitude for their protection and care during their stay.
