In SABAP 1 published
in 1997, Andre Boshoff wrote: "Although numbers have decreased locally in
many areas, often dramatically, the Martial Eagle is still widespread in
southern Africa ... The conservation status provides cause for concern ... The
main causes [of the decrease] are direct persecution (shooting and trapping) by
small-stock farmers, indirect persecution by poisoning, drowning in
sheer-walled reservoirs, reduction of natural prey through habitat alteration
and degradation, and electrocution on electricity pylons."
Unfortunately
this process seems to have been ongoing
between SABAP1 and SABAP2.
SABAP 2 shows
that the majestic Martial Eagle are not doing well throughout the Southern
African region.
The Martial Eagle - Polemaetus
bellicosus - is the largest of all African eagles. It can be found in all
sub-Saharan Africa, they are most common in the more southerly areas such as Kenya, Botswana
and South Africa.
They are more easily seen in protected areas and large parks wherever the food
is abundant and the environment is suitable. It prefers open savannah and semi
desert regions.
Description
Adults have dark
brown upperparts, head and upper chest. The body underparts are white spotted
with black. The underwing coverts are brown, with pale flight feathers, also
streaked with black. The female is larger and more spotted than the male. The
immature is paler above and has white underparts. It reaches adult plumage in
its seventh year.
Call
A loud call, 'klee-klee-klee-kloeee-kloeee-kuleee'.
Food
The diet of the
Martial Eagle varies greatly with prey availability and can be dictated largely
by opportunity. Diet consists of Birds, Reptiles, Mammals such as Hares,
Mongooses, Hyraxes and small Antelope.
The Martial Eagle
hunts mostly in flight, circling high above its territory, and stooping sharply
to catch its prey by surprise.
Breeding
The female builds
the nest which is a huge construction and is used year after year. They have a
slow breeding rate, laying at most one egg every two years. The egg-laying
season is from February to August, peaking from April to June. The egg is
incubated for 45 days. The chick is brooded almost constantly by the female for
2-3 weeks and the chick fledges at about 100 days. Beyond this, despite
becoming increasingly independent, juvenile birds will remain close to the nest
for another 6 months.
Conservation Status – Near Threatened
This species is
currently experiencing a major decline in numbers, due to the over killing from
hunters. Martial Eagle suffers from persecution through shooting and poisoning,
but also from indirect threats, such as collision with power-lines. Another
hazard is caused by steep sided farm reservoirs, in which many birds drown. In South Africa it
may have lost 20% of its population in the last three generations. In many
areas where they come into contact with humans, eagle populations have
decreased greatly through persecution, because they are blamed for killing
livestock. In reality, domestic animals constitute only a small proportion of
their diet, whereas the presence of eagles is a sure sign of a healthy
environment. The preservation of this species depends on education of farmers,
and the direct protection of nesting sites.
