The Himalayan Bluetail (Tarsiger rufilatus), also known as the Orange-flanked Bush-robin, is a small, strikingly colored bird found across the Himalayan mountain range, from northeastern Afghanistan through Tibet and into western China.

This bird is well-known for its vibrant and distinctive plumage, especially in males, which sport deep blue feathers on their head, back, and tail, with bright orange flanks that stand out against the snowy and forested landscapes they inhabit. Females, while less colorful, have a subtle beauty with olive-brown upperparts and a hint of blue on their tails.

Himalayan Bluetails prefer high-altitude habitats, particularly moist evergreen forests, bamboo thickets, and rhododendron forests. In winter, they migrate to lower altitudes and can sometimes be found in the dense undergrowth of lower mountain slopes, where they are easier to observe. Their diet consists of insects, berries, and small invertebrates, which they skillfully hunt by foraging through the underbrush and occasionally catching insects in mid-air.
