Hill Partridge vs Tibetan Partridge

Repeated melodic whistle 'wi-WHEEEOO' rising and falling; pairs often duet. Males sing from hillside undergrowth at dawn. Alarm is a sharp, emphatic 'kek' or staccato clucking.

Harsh, grating 'kerrr-ik' calls repeated from high-altitude Tibetan scrub; somewhat similar to Grey Partridge but raspier. Alarm is sharp cackle. Pairs call antiphonally at dawn across plateau.

Male has orange-rufous face, white-spotted black throat collar, grey breast, and chestnut flanks streaked white on dark brown back. Female has brown face with buff streaking, less vivid collar.

White face with bold black mask through eye; chestnut-orange flanks heavily barred white; grey crown and nape; brownish upperparts; white underparts with chestnut horseshoe patch on belly.
