Way of life

A female martial eagle on the eyrie

Martial eagle pairs live in areas of up to 250 km² . The pairs breed at intervals of about 50 km, which makes the martial eagle the bird with the world's lowest population density .

Reproduction

The breeding season lasts from November to July and shifts within this period depending on the latitude . The female builds the nest almost alone. The eyrie is built in a fork of a branch or a flat treetop and has a diameter of up to 2 m and a height of 1.5 m. When the hatchery is complete, the female lays a single beige, brown-speckled egg that weighs around 190 grams.

The young eagle hatches after a breeding period of 6 to 7 weeks. At three and a half months, the youngster makes its first attempts at flight and remains near the eyrie for a while. It finally gets its adult plumage at the age of six to seven.

food

Martial eagles mainly eat vertebrates weighing around 1 to 5 kg, namely bottom-dwelling small to medium-sized mammals ( hares , hyrax , meerkats , small antelopes or their young (such as young impala or duiker ), including jackals ) and larger birds (e. B. . fowls , waterfowl ) and reptiles ( lizards , sometimes smaller prey such as snakes and lizards ); they also take smaller pets of the same size as young goats , young sheep , dogs, and poultry.

Spread and threat

The range of the martial eagle

Martial eagles live everywhere south of the Sahara in Africa , except in the forest regions and on the southern tip of South Africa. Although humans are its only enemy , the martial eagle is endangered and is hunted as soon as it gets too close to settlements as many farmers fear for their livestock . A steady decline in the population can currently be observed.
