The Nahanfrankolin ( Ptilopachus nahani ) is a species of bird from the family of quail . With a population of 30,000–70,000 living specimens, it has been an endangered species since 1988.
features
The Nahanfrankolin is 23–26 cm long and lives hidden in the forest . His black abdomen is patterned with striking white dots. The plumage is speckled black-brown on the upper body . Its chin is white, the base of the beak , the legs and the bare skin around the eyes are red. Neither males nor females carry spurs . The fledglings are darker overall, only the lower body and neck are spotted and they have gray legs. The call consists of a rapid sequence of double tones that slowly increase in speed and volume over a period of 5–20 seconds.
distribution
The Nahan Frankolin is native to the forests in the east of the Democratic Republic of the Congo from Yangambi eastwards and in central and western Uganda in Budongo, Bugoma and Mabira . The latest research has shown a population of around 32,800–59,100 in Uganda . Since the forests of his homeland are being destroyed faster and faster, it is assumed that the population of the Nahanfrankolin is also falling sharply. Both massive logging and industrialization of the region, as well as hunting by miners who use its meat and eggs , accelerate the decline of the population. Another big problem is the settlement of the paper mulberry tree, originally native to Southeast Asia , which, as an invasive species, is gradually displacing the native trees.
Way of life
The Nahan Frankolin lives in the lowlands in primary forests and prefers swampy areas near rivers . In Uganda it appears in natural as well as industrially used forests, as well as in mixed forests . Sometimes it approaches the edges of the forest to search for food and even looks for unforested areas. But he prefers to look for food in the thick undergrowth. He feeds mainly on insects , young shoots, seeds and buds . The Nahanfrankolin lives in pairs and stubbornly defends its territory all year round. A special focus is on the period shortly before the start of the rainy season . It builds its nest on the ground between the roots of large trees.
