Thomas's pika (Ochotona thomasi), also known as the Thomas-pika,

least concern
in 2008.

Taxonomy

Thomas's pika is a

Ochotona cansus), with a similar greatest skull length, but can be distinguished by its smaller skull and cheek bone width. In 1974, Feng and Kao synonymised O. t. cilanica Bannikov 1960[6] with Ochotona thomasi.[4] According to Mammal Species of the World, O. ciliana Bannikov, 1940 is currently its only synonym.[2]

Description

Thomas's pika measures 10.5 to 16.5 cm (4.1 to 6.5 in) in length, and weighs 45 to 110 g (1.6 to 3.9 oz). The fragile skull is broader anteriorly, and smaller, flatter, and narrower than other pika species. The greatest skull length is 3.3 to 3.7 cm (1.3 to 1.5 in). The

underparts are yellow tinged or light white in colour. The winter dorsal pelage is mouse grey in colour, and the hairs have noticeable black tips. The hindfeet are 2.2 to 2.9 cm (0.87 to 1.14 in) long.[7]

Distribution and habitat

Endemic to China, Thomas's pika is rare,[1] and no intensive population studies have been conducted.[8] It is found on the secluded mountains of the eastern Qilian Mountain range in Qinghai, Gansu, and northwestern Sichuan.[1]

It inhabits meadows and isolated hilly, shrubby forests of

Salix),[7] at elevations between 3,400 metres (11,200 ft) and 4,020 metres (13,190 ft) from sea level.[1]

Thomas's pika is

Ochotona thibetana) but there is no overlap in the ranges of Thomas's and Moupin pikas.[4]

Behavior and ecology

Thomas's pika is a diurnal[1] burrowing species.[4] It is a generalist herbivore, and may live in small family groups.[1] Although its ecology is not well known, it is thought to be similar to that of the Gansu pika.[7] Details about its behaviour and reproduction are also unknown.[4]

Status and conservation

In 1994, Thomas's pika was assessed as insufficiently known on the 

least concern. This is because, although very little is known about its status, it is a widespread species. The current state of its population trend is unclear. It may be affected by killing due to pest control measures in its range although its effects to the species is unknown. There are no conservation measures to protect Thomas's pika.[1][8]
