The Barbary Partridge ( Alectoris barbara ) is a bird art from the family of pheasant-like (Phasianidae) used to order the chicken birds heard (Galliformes).
Appearance
The rock grouse is similar to the alpine stone grouse . The most noticeable distinguishing features are the throat spot and the over-eye stripe, which is light blue-gray in this species. The rock grouse also has a maroon collar that is spotted white. Behind the eye there is a long, vertical, pink stripe.
The rock grouse is a ground dweller that is rarely exposed. It is considered a shy loner.
voice
The rock grouse is most likely to attract attention by its calls, which can be heard for miles under favorable conditions. It is a piercing, high-pitched Tschruih call that rises in pitch. A hard and rough kraik or krelik can also be heard from the rock hen . The rock hen assumes a very high show posture while calling. The calls sound every five seconds. Occasionally two neighboring rock hens call alternately.
Distribution area and habitat
The distribution area of the rock grouse extends from the northern edge of the Sahara to northwestern Egypt and Morocco . It is also found on Fuerteventura , Tenerife , Lanzarote and Gomera , where it is believed to have been introduced by humans. The population found in Sardinia may also have been introduced. Four subspecies are described within this distribution area:
- A. b. koeningi ( Reichenow , 1899): NW Morocco, introduced in the Canary Islands and S Spain
- A. b. barbara ( Bonnaterre , 1792): N-Morocco and Algeria ; Sardinia (introduced?)
- A. b. spatzi ( Reichenow , 1895): S-Morocco to Central Algeria and S- Tunisia
- A. b. barbata ( Reichenow , 1896): Libya and NW Egypt
The species is very adaptable. In addition to cultivated land, it occurs in euphorbia steppes , in eucalyptus forests and in the mountains up to the snow line. The clutch consists of ten to 14 eggs, which are red-brown spotted. The incubation period is 25 days. The young birds stay together with the adults until the next breeding period.
