Stone Partridge
Ptilopachus petrosus
Unusual partridge that is small and dark, with a thick tail that is usually cocked up. A good view reveals red legs, red bare skin around the eye, and fine markings on the breast and head. There is some regional variation: the plumage is generally darker in moister areas and paler in drier areas. Found in a variety of savanna habitats with a thick and grassy understory, often in rocky areas. Usually in pairs or small groups. The distinctive vocalization is a series of loud “wheet” notes that rises and becomes more emphatic, usually given as a duet by a pair. Cocks up the tail like Crested Francolin, but smaller, darker, and without a bold pale eyebrow stripe.

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.<p>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.

The stone partridge was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other partridge like birds in the genus Tetrao and coined the binomial name Tetrao petrosus. Gmelin's description was based on the Comte de Buffon's "Le perdrix de roche ou de la Gambia" and John Latham's "Rufous-breasted partridge". The stone partridge is now placed with Nahan's partridge in the genus Ptilopachus that was introduced in 1837 by the English naturalist William John Swainson. The genus name is from the Ancient Greek ptilon meaning "feather" with pakhus meaning "thick" or "dense". The specific epithet petrosus is Latin meaning "rocky".<p>Four subspecies are recognised:<p>Some confusion exists in the naming of this species because the name of this bird in many languages translates literally into English as "rock partridge". For instance, in Dutch the species is rotspatrijs, in German - Felsenhenne, in French - poulette de roche - all literal translations of "rock partridge". The bird known as rock partridge in English is actually a member of another genus, Alectoris graeca. The confusion is further compounded as in some languages, Alectoris species are known by names that literally translate as stone partridge. In Dutch, steenpatrijs, in German Steinhuhn; red-legged partridge (A. rufa) being rode steenpatrijs in Dutch. Further complication arises as, particularly within the US, the name "rock partridge" has been used for a variety of Alectoris species and hybrids. The international bird trade, for sport, aviaries' and meat, has led to misapplication of various of these common and scientific names. Alectoris and Ptilopachus species are actually very different in size and habits, Ptilopachus being only 20–25 cm long.

分布与栖息地
Widespread and common throughout its large range, the stone partridge is evaluated as least concern on the IUCN Red List of Threatened Species.<p>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.

Onychognathus salvadorii
A large blue-black starling with a fuzzy bump on the forehead. The very long and pointed tail and large red wing panels are conspicuous in flight. Found around cliffs and other rocky areas in dry savanna and thorn scrub habitat. Sometimes sits on domestic animals. Similar to other red-winged starlings, but note the larger size, the more pointed tail, and the forehead bump. Gives a variety of simple vocalizations, of which the most common is a two-part “chu-pit.”
