3-11-2021 BIOPARC, VALENCIA - STONE PARTRIDGE (Ptilopachus petrosus)

The stone partridge (Ptilopachus petrosus) is a bird of the New World quail family. This largely brown bird, which commonly holds its tail raised, is found in scrubland and lightly wooded habitats, often near rocks, from Kenya and Ethiopia to Gambia (a large part if its range is in the Sudanian Savanna).

The stone partridge is exceptional among gamebirds in that the female, to human eyes, is showier than the male. Both sexes are predominantly earthy chocolate brown above, with sparse, pale, cream-grey spotting. The head, neck, and chest are paler brown and have broad cream edging to the feathers that gives the bird a scaled appearance. In males, the lower chest and belly are orange-cream; in females, very pale cream. Both sexes raise their crown feathers to form a rudimentary crest, but the feathers of females are somewhat longer, hence more obvious when raised.

Eggs are pale pink, fading to cream; juveniles are dark chocolate-brown throughout, moulting into adult plumage at several weeks old. In captivity at least, the male plays a major role in both incubation and rearing of the young, offering young small items of food by picking them up, dropping them, and calling to the chicks.

Widespread and common throughout its large range, the stone partridge is evaluated as least concern on the IUCN Red List of Threatened Species.

Since 2000, the stone partridge has been imported into the United States and Europe, where it is hoped that it will become established in zoos and bird collections.

The stone partridge is featured on a 5F stamp of Ivory Coast.
