Tassonomia

The rufous-throated partridge was formally described in 1849 by the English zoologist Edward Blyth based on birds from the Darjeeling district of the state of West Bengal in eastern India. He coined the binomial name Arboricola rufogularis where the specific epithet combines the Latin rufus meaning "red" with the Modern Latin gularis meaning "throated". The rufous-throated partridge is now one of 19 partridge species placed in the genus Arborophila that was introduced by Brian Hodgson in 1837.<p>Six subspecies are recognized:

Comportamento

This partridge feeds in groups of five to ten birds. It eats seeds, plant shoots, berries, insects and snails. Surprised birds run or fly, sometimes flying to branches like some thrushes. Birds in a covey roost and huddle together in trees, similar to babblers. Breeding has been recorded from April to July in India and from February to May in China. The male builds a scrape in bamboo, forest undergrowth or along water. The nest is lined or padded with grass. Three to five white eggs are laid. The rufous-throated partridge gives a rising series of hu-hu whistles. In a duet, the partner's call is kew-kew-kew.
