The Kaptriel ( Burhinus capensis ) is one of the nine species of the genus Burhinus , which is the only one of the Triele family (Burhinidae) within the order of the plover-like (Charadriiformes). The species is very widespread in Africa and a frequent breeding bird in arid and semi-arid regions south of the Sahara. Although the species is absent in more grazed regions, overall there does not appear to have been any major loss of area during the 20th century.
Habitat and Distribution
Their habitat is the savannah , the bushland and the semi-desert in eastern and southern Africa. The following four subspecies are distinguished:
- the nominate form Burhinus capensis capensis , which occurs in the extreme south of Africa.
- the subspecies B. c. damarensis , which is slightly paler and grayer than the nominate form and lives in the arid south-western zone of Africa.
- the subspecies B. c. maculosus , which has a slightly more strongly colored plumage and is overall a bit more reddish than the nominate form.
- the subspecies B. c. dodsoni , which is paler than the subspecies B. c. maculosus and on the Red Sea as well as from Eritrea to southern Africa.
The Kaptriel is basically a standing bird. In southern Africa, however, there are partial trains after heavy rains. The Kaptriele then migrate to drier regions. The longest hike from Kaptrielen in the interior of Africa, documented by ring finds, covers a distance of only 169 kilometers. Cape trike, which occur in coastal regions, even seem to be very sedentary birds. A full-grown bird ringed near Port Elizabeth was found just four kilometers from the original ringing location 22 years later.
Kaptriele live in pairs or in small families. The game population is not threatened.
Way of life
The Kaptriel is a predominantly crepuscular and nocturnal species. During the day it usually rests in thick bushes. Its diet consists of worms, insects, reptiles and seeds.
The breeding season is in spring. The birds build a simple ground nest and lay two eggs. After four weeks of incubation, the chicks leave the nest immediately after hatching. Kaptriele are fully grown after one year and have a life expectancy of 20 years.
