s this 28–31 cm long partrdige has the brown back, blackish belly patch and chestnut flanks of its relatives, but has a striking black and white face pattern, which contrasts with the rufous collar.

The forehead, broad supercilium, face and throat are white. A broad black stripe runs down the face from below the eyes and it has a broad chestnut hind neck collar. The upper parts are buff, barred with rufous and black. The other tail-feathers are chestnut, tipped with white. The lower plumage is pale buff closely barred with black, with broad chestnut bars on the flanks. The male has black belly patch which is barred in female. The female is otherwise similar to the male but duller, and the juvenile is a featureless buff-brown, lacking the distinctive facial and underpart markings of the adult. Sexes are similar in size.

Taxonomy and systematics

The scientific name of Sacfa hodgsoniae was given by Brian Houghton Hodgson

Brian Houghton Hodgson was an early naturalist and ethnologist working in British India and Nepal where he was an English civil servant. He described many species, especially birds and mammals from the Himalayas, and several birds were named after him by others such as Edward Blyth...

 to commemorate his first wife, Anne Scott. The original genus proposed by Hodgson was based on the Tibetan name for it, Sakpha. There are 16 tail feathers while most other Perdix species have 18. Neither males nor females have spurs on their legs. Phylogenetic studies place the species as basal within the genus. There are three subspecies differing mainly in the plumage becoming darker further east:
  • hodgsoniae, described by Hodgson, is found from eastern Tibet, through western Nepal, to northeast India (Assam). The nuchal collar is broad and dark chestnut. The black of the cheek extends below throat as a collar.
  • sifanica, described by Przhevalsky

supply.

The Tibetan Partridge forms flocks of 10-15 birds outside the breeding season, which tend to run rather than fly. When disturbed sufficiently, like most of the game birds it flies a short distance on rounded wings, the flock scattering noisily in all directions before gliding downhill to regroup.

In summer beginning around mid-March the birds pair up to form monogamous bonds with the pair staying close together. The nest site varies from bare rocky plateau with few stunted bushes and tufts of coarse grass to small thorny scrub or even standing crops. Nests tend to be close to paths. The nest is a grass-lined depression, sometimes devoid of any lining. The typical clutch is 8-10 brownish-buff eggs and is laid during May to June. The male assists in looking after the young.

The usual call heard mainly in the mornings is a rattling scherrrrreck- scherrrrreck , and the flight call is a shrill chee chee chee.

In Lhasa these partridges appeared to prefer stream belts with scrub and in winter they preferred south-facing slopes and open fields. They sometimes rest under bushes in the day and roost under dense scrub at higher elevation slopes in the night. They form pairs during the breeding season and after the breeding season form larger groups.
