Whereas on the best way to some other place I discovered the bluest thrush.

Based on Birds of the World, the grandala (Grandala coelicolor) is a gregarious thrush that makes a vertical migration within the Himalayas and Tibetan Plateau(*) from barren alpine breeding grounds at 3900–5500 m (12,800-18,000 ft) to rocky mountainside valleys and ridges at 3000–4300 m (9,800-14,000 ft), generally as little as 2000 m (6,500 ft).

To place this in perspective, if grandalas lived within the U.S they may solely breed on Denali (20,000 ft) or the best Rocky Mountains. A few of them by no means come down as little as the best level the Rockies, the height of Mount Elder.

Grandalas are the identical measurement as wooden thrushes and just like the wooden thrush are the one species of their genus, however there the similarity ends. For example, grandalas are sexually dimorphic with royal blue males and brownish-gray females.

Grandalas have versatile diets tuned to their chilly local weather lives. They eat bugs in summer season and fruit in fall and winter.

Like cedar waxwings grandalas journey in large flocks in fall and winter. After they perch they flick their wings and tails.
