Turdus rubrocanus (Chestnut Thrush)
The Chestnut Thrush (Turdus rubrocanus) is a medium-sized thrush species that is frequently observed in the temperate forests of the Great Himalayan National Park (GHNP). Known for its rich chestnut-brown plumage, especially on its underparts, this shy bird adds both color and melody to the serene landscapes of GHNP.
Appearance and Identification
The Chestnut Thrush is easily identified by its chestnut-colored belly and flanks, complemented by darker brown upperparts and a subtle greyish head. Its song is soft and flute-like, often heard during early mornings and late afternoons. Both male and female birds look similar, although males tend to have slightly glossier feathers.
Habitat and Behavior in GHNP
In GHNP, the Chestnut Thrush is mostly found in high-altitude coniferous and broad-leaved forests. It thrives in moist temperate zones, particularly between elevations of 2,000 to 3,500 meters. This bird forages on the forest floor, often seen flipping through leaf litter in search of insects, worms, and fallen berries.
Although generally solitary or seen in pairs, they may form loose flocks during migration periods. They are more active during dawn and dusk, making them a delight for patient birdwatchers.
