Song & Call Comparison
Hill 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.
Black Partridge
Infrequently recorded; gives a series of sharp, nasal 'krek' calls from peat swamp forest floor. Alarm is a low explosive cluck; poorly documented due to rarity and secretive habits.

About These Birds
Hill Partridge
A medium-sized partridge (~340 g) of family Phasianidae, with intricate rufous, black, and white patterning and an orange-rufous head. Inhabits subtropical and montane broadleaved forests and bamboo thickets in the Himalayas from Pakistan to southwestern China. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; common in Himalayan foothills.
Black Partridge
A small sexually dimorphic partridge (~280 g) of family Phasianidae, males entirely black and females rufous-brown. Endemic to lowland rainforests of the Thai-Malay Peninsula, Sumatra, and Borneo. Highly secretive, foraging on the forest floor for seeds and invertebrates in dense undergrowth. Vulnerable; declining with rapid lowland deforestation and conversion to palm oil plantations.
