Royle's pika

The most common pika species in the Himalayas, it has a length of 17-22 centimeters. Royle's pika has a slightly arched head, with a rufous-grey body and chestnut-colored head, as well as sparse hair in front of its ears.

This is the most common pika species in the Himalayas, and can be confused with the sympatric large-eared pika. These species are mostly seen in the open rocky mountain edges or slopes, or on ground covered with conifer trees, such as pine, deodar and rhododendron forests. Royle's pika tends to forage for food during monsoon season, due to greater food availability and rest during middays, when the temperature increases. The species has also been found near human habitation. It does not make its own nest; rather, it takes narrow creeks and existing burrow systems as its nest, filling it with hay piles and pine leaves. It also uses the rocky areas on the mountains to take refuge and escape from predators.

Though their conservation status according to IUCN Red List is "Least Concern", habitat loss and human habitation in hilly areas are the indirect cause of conservation threats towards them.
