Besides the traditional roosting areas, the bird has been reported exploring new areas or being mis-directed by weather conditions during its migration.
In 2010 winter, 347 cranes were reported to have visited the Phobjikha valley.
- In Bumdeling (the second highest wintering site in Bhutan), frequent monsoon floods have washed away the paddy fields that cranes forage on.
- Loss of habitat due to anthropogenic pressures like irrigation, roads, tourism, construction etc.
- Cranes also risk being killed by predators like leopard, wild dog and red fox.
- Global warming is yet another cause that will have an adverse hand in hampering its habitat.
