The gray stripe francolin ( Francolinus griseostriatus ) is a monotypical bird of the genus Frankoline ( Francolinus ) from the pheasant-like family . Its distribution is limited to Angola and little is known about its way of life. Due to the armed conflict in Angola that has raged for decades, no inventories of this species have been taken for a long time. The IUCN therefore classified the gray stripe francolin as endangered ( vulnerable ) or as potentially endangered ( near threatened ) until 2008 . The current political situation in Angola has allowed this assessment to be corrected: The IUCN has sufficient evidence to suggest that there is a sufficiently large population of this species. Since 2012 the gray stripe frankolin has been classified as (= least concern - not endangered).
features
The gray stripe frankolin reaches a body length of 29 to 31 centimeters. The wing length is between 13.9 and 16.1 centimeters, the tail is 8.7 to 10.2 centimeters long. There is no noticeable gender dimorphism . The females are only slightly smaller, the males have a long spur on their orange-red legs.
The gray stripe Frankolin has a light yellow abdomen with reddish brown spots that also decorate the light gray wings . The feathers on the sides of the neck and on the back of the neck, on the coat, the back and the shoulders are dark maroon. On both flags of a feather there is a black and a pearl gray longitudinal band as well as an irregular black stripe and ribbons. The rump and the upper tail-coverts are gray-brown with an indistinct, lighter wave pattern. The tail is dark brown with indistinct black bands. On the head, the forehead is rust-brown, the crown and the nape are gray-brown, while the sides of the head are light gray-brown. The area around the eyes is maroon, the beak is black, the root of the beak and the legs and feet are bright red.
In young birds, the basic color of the upper side of the body is cinnamon brown. The breast is less reddish brown and the belly whiter than that of the adult birds. The voice of the gray striped Frankolin should correspond to that of the Schuppenfrankolin .
The gray-stripe francolin is unmistakable in its area of distribution: there is no other species that occurs primarily in forest areas in this region and has a chestnut-brown-striped body plumage and bright red beak and legs.
distribution
The gray stripe francolin is native to some parts of Angola . It was first discovered in 1957. A sizable population was found in Quiçama National Park in 2001. As early as the early 1970s, the establishment of a 20 km² protected area in the Chongorói region was recommended. However, this project has not yet been implemented.
Way of life
The gray-stripe francolin lives in secondary forests as well as in thickets and grass-covered areas in northern Angola. It can also be found in the extremely dry and dense forests and thickets that are typical of the northern coastal plain . In the early morning hours and in the afternoon, it feeds on the grasslands and in the cotton fields bordering the forests on small insects , young shoots and seeds.
