Strange Ways
Many
species of Old World vultures live throughout
Africa and have a great impact on their surroundings. They vary
from small birds with slender bills, such as hooded vultures, to
large hunters with heavy bills, such as African white-backed vultures.
These important adaptations help vultures survive and perform important
roles in the environment.

Dinner is
Served
Vultures
feed on the carcasses of dead animals,
sticking their heads deep into the body cavity to pick bits of food.
Some species also hunt small prey, such as insects, lizards, smaller
birds and rodents. Pieces of decaying meat and skin are less apt
to stick to bare heads than to a thick mat of feathers. When vultures
bask after meals, the heat of the sun dries any potentially bacteria-ridden
bits of food that easily fall off, helping them remain healthy.
Vultures
have keen eyesight. It is believed they are able to spot a three-foot
carcass from four miles away on the open plains. In some species,
when an individual sees a carcass it begins to circle above it.
This draws the attention of other vultures who then join in. Once
the vultures have landed, they fight and bicker over feeding spots.
For the most park, many vulture species are relatively silent, but
not when it comes to a prime place at the dinner table! Once on
the carcass, vultures plant their talons for
stability and pull at the flesh with their beaks. Many species of
vultures feed together with little competition, because they do
not feed on the same kind of meat within the carcass. There are
even vultures that feed on the bones! Since the entire carcass can
be eaten, nothing is wasted. Vultures are such efficient feeders
that the body of a small animal can be skeletonized in less than
half an hour.

Family Tree
Vultures
usually have one mate a year. Nests are constructed using sticks
and leaves, and are built in trees and cliffs. The same nest may
be used for several years. Most species produce one chick; the male
and female share parental responsibilities. They take turns sitting
on the nest while the mate finds food that, upon return, is
regurgitated for the hatching.

Suffering
Survivors
Vultures
play a prominent role in African folklore. Their ability to show
up wherever there is a carcass leads many to believe they dream
the location of food or use telepathy.
They
have long been misunderstood and persecuted by humans, suffering
from loss of habitat and from poisons that can accumulate through
time in their prey. New World vultures in America, such as California
condors, have also been devastated by pesticides
and habitat loss. Thankfully, captive breeding programs helped restore
these magnificent birds. Vultures serve an important function as
nature's garbage collectors, helping to keep ecosystems
clean of waste. Habitats must be preserved and pollutants eliminated
so these important predators are not lost.
