Hawks are
birds of prey
Hawks
are birds of prey. They are found throughout the world,
except in the Polar regions. They vary greatly in size
and appearance, but all have a pointed, down-curving
bill, sharp, strong talons and large wings with rounded
tips, observes Nutan Shukla
CRANE hawk, which belongs to Central
and South America along with two species of harrier
hawk of Africa form a group of woodland
hawks which has a unique adaptation for catching prey,
unheard of any other bird. Middle joints (tarsal) of
their legs are such that the legs can bend either way.
This adaptation is most beneficial for the bird when it
is searching for prey in the difficult and awkward
crevices in rocks or tree trunks. While doing this these
birds are usually seen in most unusual positions such as
hanging upside down or bending sideways. Their food
includes small reptiles, like lizards, eggs and nestlings
of other birds and other animals like frogs.
Another bird,
Coopers hawk, a cousin of crane hawk, found in the
woodland habitats of North America from Canada south to
Mexico, employs a mixture of skill, speed and trickery
while hunting. It uses natural cover, like big cats do,
to get closer to the prey. While doing this it swoops in
low, using every possible object like tree stump, stone
or bush to conceal itself.
Sometimes, while the birds
are hiding in a bush, it uses the method of frightening
them out of their cover. A species of sparrow hawk,
Coopers hawk, flies straight towards a bush, which
frightens the birds hiding in it and they start running
helter-skelter. The hawk as it reaches the bush dodges
sideways at the last minute, dashing round to the far
side and catches the bird which first comes out in the
open.
Females of these hawks are
much larger than the males. They pray upon the birds as
big as grouse while males do not go beyond the size of
starlings or blackbirds.
Hawks are birds of prey.
They are found throughout the world, except in the polar
regions. They vary greatly in size and appearance, but
all have pointed, down-curving bill, sharp, strong talons
and large wings with rounded tips. Hawks feed on a wide
variety of animals, such as reptiles, fish, insects and
small mammals. They have very good eyesight and swoop
down on their prey from high up in the air.
Another cousin, the bat
hawk, is the only known bird of prey which specialises in
bat-hunting. Found in the rainforests of New Guinea,
Malaysia, Sumatra, Borneo, and in tropical Africa, it is
also unique in the sense that it does not carry its prey
in its talons, like hawks do. Instead it carries in its
bill, like owls.
Buzzards are another group
of birds of prey, related to hawks. They are large birds
with broad wings. They soar high in the sky, prefering
wooded and hilly country. They feed on rabbits, mice and
other small animals, and have a distinctive mewing cry.
The black-breasted
buzzard, an Australian bird, is reputed to do the same
exercise with emu eggs what Egyptian vulture does with
ostrich eggs. Buzzards chases away the parent emu from
the nest and then drops rocks on the eggs to break them
open. Ostrich eggs are very large and tough. To break
them open Egyptian vulture throws stones on it to get at
the bonanza of nutritious yolk inside.
Honey buzzards feed mainly
on the larvae of bees and wasps. To protect them from
being stung by these insects, mother nature has provided
them with stiff feathers on the face. They are
medium-sized birds, which are mainly brown, but can be
variable, with a barred tail. Found in Asia, Africa and
Europe, some of these birds of prey have crested heads.
They are the birds of woodland and nest in trees.
The males of honey
buzzards alone discharge the duty of hatching the eggs
following the death of the female. Both partners build
large nest with twigs which they line with fresh green
twigs and leaves. Usually the duty of incubating the eggs
is shared by both the parents. Both parents feed the
chicks.
