The African harrier hawk is also known as the gymnogene, which means bare cheeks.
The African harrier hawk is like many other raptors, except for
its unfeathered face, which blushes to a deep red when startled or during
mating displays. The African harrier hawk is uniquely equipped for a life as a
stealthy hunter; it has extremely keen vision for locating elusive prey. They
found in Africa: South Africa, east to Natal, north to Botswana, northern
Namibia, Zimbabwe and Mozambique, then north to the Sahara Desert.
Habitat : The African harrier hawk frequents a variety of
landscapes throughout its range in central and southern Africa, including
forest, woodland and savannah. It is most often found at the top of tall trees
fringing the larger rivers or in hilly country where there are deep ravines and
steep hillsides.
Food & hunting : The African harrier hawk seeks out elusive
prey. With its ability to bend its legs forward and backward, this hawk can
reach deep into holes or crevices and grab prey that is safe from other
raptors.The African harrier hawk shows a variety of hunting skills: it climbs
around on the branches of trees, using its wings for balance; it hangs upside
down for long periods of time as it explores nooks and crannies for a hidden
meal; it soars slowly along the edge of hillsides and ravines and scans
carefully for potential prey. Unlike other raptors, this hawk is not a very
powerful bird and normally settles for prey about as large as a lizard. In
certain parts of its range, the African harrier hawk is known to eat the fruit
of the oil palm, but mostly its diet consists of lizards, small birds, insects
and rodents.
Behavior : The African harrier hawk’s most unusual behavior is that
it blushes. Whereas most raptors have feathered faces, this hawk’s face is
unfeathered to assist it in probing into holes for food. Unexpected
disturbances, such as a branch snapping, can trigger the face (normally pale
yellow) to blush a deep red. Encounters between breeding pairs also result in
blushing; this is believed to represent an appeasement signal, especially
during courtship, and switches in incubation duty.
Breeding : Courtship for the African harrier hawk occurs in the
air. At the onset of the breeding season, the pair can be seen soaring together
in display flights involving shallow dives and upward swoops accompanied by
drawn-out whistles. These displays usually end in a long glide to the nest
area. The stick nest is built in a tree by both sexes, usually from 30–150'
from the ground, and is lined with green leaves. Usually 2 eggs are laid and
both sexes incubate. After about 35 days, the eggs hatch at different intervals
and the younger sibling usually dies of starvation as its older sibling takes
all the food.
Bill : The hawk’s hooked bill is used to tear the flesh of its
prey. Its nostrils are protected by a soft membrane called the cere.
Wings : The long, broad wings, paired with a small body, give this
hawk its exceptional ability to sail slowly near the ground or the edges of
hillsides while scanning for prey.
Legs & Feet : The hawk’s intertarsal joint, or “knee,” can bend
backward and forward, allowing the bird to reach deep into holes to snatch
prey.
Juvenile : Immature birds are dark brown with varying amounts of
light-brown edging to the feathers.
