sloth bear, U. ursinus.
Range of the spectacled bear.
DISTRIBUTION
Found in a variety of habitats and altitudes in the Andes region
of South America, from Venezuela to Bolivia and Chile.
CONSERVATION
The spectacled bear is considered threatened. All of its habitats
are at risk from human interference and attempts to prohibit
hunting have not been very successful.
FEATURES OF THE SPECTACLED BEAR
Body: Although it is among the smaller
members of its family, the spectacled
bear has a typically heavy body. It has
short, powerful limbs, a short tail,
and a large head. Eyes and ears
are relatively small , and hear-
ing and sight are not as
acute as the keen
sense of smell. The
two sexes differ
widely in weight
and size.

Coat: Thick. Uniformly black or dark brown,
except for varying amounts of white markings
on the face and chest. The white markings
around the eyes give the bear its name.

The spectacled bear gets its name from the distinctive white
markings around its eyes. These markings extend to the
bear's muzzle and chest, providing a sharp contrast to its
dark brown or black coat. The markings vary considerably
between individuals in different parts of the animal's range
and barely appear at all on some spectacled bears.
~ HABITAT
The spectacled bear lives main
ly in the Andes, at elevations of
5,000 to 6,500 feet. Its range
stretches from Venezuela and
Colombia south to Bolivia and
Chile. Although it prefers the
humidity of rainforests, the bear
also settles in grasslands and
semiarid scrubland.
The relative lack of oxygen at
such high altitudes slows most
animals down. But the specta
cled bear seems remarkably un
affected. A hardy, agile climber,
it forages constantly among
the trees.

sections of its lower mountain
habitat, and the land is now
used for grazing cattle.
Attempts to protect the spec

• The spectacled bear makes
a nest from the branches of
the trees in which it forages.
Using these branches, it con

~ FOOD &: FEEDING
The spectacled bear eats main
ly the leaves, stems, and roots
of plants. It is also fond of fruit.
In the semidesert regions of
Peru, this bear often feeds on
cacti. In the northwestern parts
of its range, it prefers young
palms, crushing their nuts and
leaves in its large, strong jaws.

The hanuman langur is an adaptable monkey that lives in
a variety of habitats throughout the Indian subcontinent.
It is considered sacred according to Hindu tradition. For
this reason, the hanuman langur is treated with reverence
in much of its range. This animal is sometimes worshipped
and may even be found entering holy temples.
~ HABITS The hanuman langur is very well
suited to living in trees. It can be
found in deciduous forests from
sea level to about 13,000 feet. It
lives in a variety of habitats, from
dry savannas to the snowy Hima
layas of Nepal.
In parts of its range where it is
considered sacred, this langur
has become bold toward peo
ple. But in other areas it stays
away from human habitations.
The hanuman langur is active
during the day. It sleeps at night
in hollow tree trunks or beneath
boulders in mountainous areas.
It moves with great agility from
one tree to the next, using its
very long, tufted tail for balance.
This animal may also spend
much of its time on the ground,
where it lopes around easily on
all fours. But the langur is more
nervous on the ground than in
the trees. At any sign of danger
it utters a barking call and then
climbs to safety in the trees.
The hanuman langur lives in a
family troop that usually con
sists of 20 to 40 langurs led by
an older male. This stable family
unit ranges over a territory of up
to four square miles. To avoid
conflict with other langur troops,
a foraging group advertises its
presence with a whooping call.
~ FOOD &: FEEDING
At dawn the hanuman langur
troop moves swiftly through
the trees, foraging for food.
The langur feeds primarily in
the trees, taking leaves, buds,
shoots, and flowers. But it also
descends to the ground and
gathers fallen fruit or nuts.
The troop stops at a suitable
spot to feed for approximately
half an hour. When the domi
nant male utters a barking call,
the langurs move off to find a
fresh food source. The troop
rests at midday.
Left: The hanuman langur is not
only nimble in trees and on the
ground, but it can also swim.
DID YOU KNOW? • In parts of India where the
hanuman langur is considered
sacred, Hindus put out food
for the langurs every Tuesday,
I which is the day of the mon
key god, Hanuman.
• Large troops of hanuman
langurs sometimes raid crops. L-
The hanuman langur copes
with a large diet of tough, of
ten indigestible food. It can eat
the fruit and seeds of the plant
Strychnos nox-vomica, without
ill effect, even though the plant
produces the poison strychnine.
The hanuman langur also seems
to like ak, a foul-smelling, latex
bearing plant that most other
animals avoid.
The langur obtains important
minerals by eating soil or lick
ing stones . It also occasionally
feeds on insects.
Right: The hanuman langur is at
home in the trees, where it finds
most of its food.
Some farmers, not wanting to
harm the monkeys, are said to
have put them on trains to far
off locations.
• When an adult male takes
over a hanuman langur troop,
he sometimes attacks and kills
the young.
The breeding season of the han
uman langur varies, depending
on the animal's location. Where
conditions are suitable, it breeds
year-round. Although males are
sexually mature at four or five
years old, they seldom mate for
another two or three years. This
is because the dominant male
prevents them from finding any
mates. He chases the younger
males away from sexually recep
tive females.
The female is sexually mature
when she is three or four years

old. She attracts the male by
dropping her tail, shaking her
head repeatedly, and beating
the ground with her hand.
After a gestation of about six
and a half months, the female
gives birth to a single offspring,
usually when food is abundant.
The young suckles for up to 10
months. The mother often lets
the troop's other females groom
her and her offspring and even
suckle the infant.
Sometimes the young langur
is reluctant to leave its mother,
even when ready to be weaned.
But it is usually independent at

The bull sable antelope is a large animal that has
an especially impressive appearance because of its long,
curved horns, which may be up to three feet long. The
sable is one of the few species of antelope that uses its
horns as weapons. The animal uses its horns to fight
other bulls when defending its territory. It also uses
its horns to fight off predators, including lions.
~ HABITS
The sable antelope is found in
open woodland or nearby grass
land where the vegetation is
fairly tall. It usually avoids dense
woods and dry savannas. It is
less able to tolerate dry condi
tions than most antelope and is
never far from water.
Sable antelope form herds of
10 to 20 cows and their calves.
Several herds may graze togeth
er in groups of 100 or more in
dividuals. The young bulls form
bachelor herds.
During the mating season a
bull establishes a small breed
ing territory that he may hold
for two years or more. At other
times he keeps to his own terri-
tory, which he marks by break
ing branches off bushes and
trees with his horns.
Sable antelope graze peace
ably with other large mammals.
But because the bulls are terri
torial, they often fight among
themselves and may be aggres
sive toward other antelope.
Although it generally flees
from danger, the sable ante
lope confronts predators if nec
essary. It has even been known
to fight off lions. If hurt or cor
nered, the antelope defends
itself fiercely. It lets out a shrill
cry as it charges with its head
lowered and horns pointed at
the enemy.
~ FOOD & FEEDING
Like other members of its fami
ly, the sable antelope is a rumi
nant-an animal that chews its
cud. This means that it returns
partially digested food to its
mouth to chew it again .
The sable antelope grazes on
grass in the early morning and
midafternoon. After eating, it
moves to a secluded spot where
it is protected from its enemies
while it chews its cud. A herd of

• The longest sable antelope
horn on record measured
just over four feet.
• The giant sable, which lives
only in Angola, is a rare sub
species of sable antelope. Its
sable antelope grazes over an
area of 4 to 125 square miles,
depending on the quality of the
grass. Even within this range the
animals are constantly on the
move. In the dry season, when
the grass is poor, the sable ante
lope may also pick at leaves on
shrubs and bushes. Although
this diet provides some mois

• The sable antelope belongs
to a subfamily called Hippo

like antelope."
• Although they resemble
deer, antelope are more
closely related to cattle.
~ BREEDING
The mating season, or rut, of
the sable antelope lasts about
two months. The rut occurs at
different times, depending on
the animal's location. In Kenya,
for example, mating takes place
in June and July. Farther south,
in Zimbabwe, the sable breeds
between May and November.
During the rut a bull controls
a herd of cows. He snorts and
uses violent sweeps of his horns
to drive off other bulls and keep
the cows together.

When naturalists discovered the aye-aye in
the 18th century, they had trouble deciding exactly
what kind of creature it was. At first, the aye-aye was
considered a member of the squirrel family. Later it was
believed to be a climbing marsupial. In fact, this primitive
primate is actually a highly specialized lemur that is
found only on the island of Madagascar.
~ HABITS
The aye-aye leads a mostly soli
tary life in the rapidly disappear
ing rainforest of Madagascar.
Naturalists have a difficult time
studying it in the wild because
it stays well hidden high in the
trees or deep in the dense bam
boo jungle.
This night-active tree dweller
depends mainly on trees for its
food. Unlike most mammals, it
builds a nest-sometimes two or
more. It spends most of the day
sleeping in the nest, with its long
tail wrapped around its body.
Waking at dusk, the aye-aye
leaps about the branches of its
territory. An excellent climber, it
can hang from branches by its
hind legs, leaving its hands free
for holding food or grooming.
At night the aye-aye comes
down from the safety of the
trees. It scampers across the for
est floor on all fours, with its tail
raised. It walks on the balls of its
hands because its fingers are so
long that it is unable to walk on
its palms.
The aye-aye uses very little vo
cal communication. It may grunt
when searching for food or make
a violent sneezing sound when
it is alarmed.
~ FOOD & FEEDING
When searching for beetle lar
vae, the aye-aye taps its thin,
bony middle finger against tree
bark and listens for sounds with
its large, sensitive ears. A hol
low echo may indicate that
there is a beetle larva's tunnel

July, when the seals molt (shed)
their fur on the pack ice be

After molting, the seals disperse.
As with other seal species, the
male is larger and heavier than
the female-he can weigh as
much as 900 pounds.
~ BREEDING
Hooded seal pups are born in
late March, when the cows
(females) come out of the
water to give birth on an ice
floe. The birth is strained since
the pup is large, weighing ap
proximately 45 pounds.
The pup is born with a silvery
blue-gray coat that has earned
it the name of "blue-back." The
mother suckles it for 1 0 to 12
days. Several bulls (males) join
her, but she is aggressive to
ward them until the suckling
period ends and she comes into
heat (is ready to mate).
As they wait for the cow to
become available, the bulls car

not establish dominance, the
bulls fight, biting and clawing
