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.

Right: Small and helpless at birth,

used for grazing cattle.

Attempts to protect the spec­

tacled bear have not been very

successful. Because of its fre­

quent descents into farmland

and its occasional attacks on

cattle, the bear is hunted by

local people who consider it a

parts of the bear's body also

have medicinal and ceremo­

nial uses.

• The French naturalist Baron

Georges Cuvier was the first

to describe the spectacled

threat to livestock. In addition,

the bear is hunted as a source

of food. Its fat is used as cook­

• The spectacled bear makes

a nest from the branches of

the trees in which it forages.

Using these branches, it con­

structs a platform on which it

rests during the day.

~ 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.

While it often tears down small

palm trees, it can easily climb

up larger ones when foraging

The spectacled bear also eats

some flesh, such as insects and

carrion (dead animals). Occa­

sionally it takes live mammals

such as llamas, cattle, and deer.

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.

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

15 months.

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

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,

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

ture, the sable also needs to

drink water every day.

• The sable antelope belongs

to a subfamily called Hippo­

traginae, meaning "horse-

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.

tors. The calf stays in hiding for

1 0 to 20 days and then enters a

older cows. The calves begin to

graze when they are just one

month old and are fully weaned

at eight months.

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

under the bark. After it has lo­

cated its prey, the aye-aye uses

its prominent incisor teeth to

chisel a hole in the bark. Then

it twists its finger inside in order

to scoop out the larva.

members of the subfamily Phocinoe,

including the harp seal, Pogophilus

groenlondicus.

Range of the hooded seal.

DISTRIBUTION

Found in the North Atlantic and Arctic Ocean from Newfound­

land and Baffin Island in the west to Novaya Zemlya in the east.

CONSERVATION

Public pressure and governmental action have reduced the

number of seals killed for their fur. With a population of 250,000

to 400,000, the hooded seal is not in danger of extinction.

Deflated: The hood is an enlarged

nasal cavity that normally hangs

down in front of the bull 's mouth,

covering the front of his face.

Inflated: When the bull gets

aroused or angry, he closes his

nostrils and blows air into the

hood to expand it.

The hooded seal lives a solitary life in the deep, icy

waters of the North Atlantic and the Arctic Ocean.

It gets its name from a covering of loose skin over

the male's nose that he can inflate at will. The male

also has a bright red membrane that he can fill

with air so that it protrudes from one nostril,

looking like a huge bubble gum balloon.

~ YOUKNOW? 1 • Hooded seals have wan-

dered as far south of their

Arctic home as Florida.

• The hooded seal is also

called the bladdernose seal.

• The two sexes seem to

live in different areas out­

side the breeding season.

• Eskimos regard hooded

seal meat as a delicacy.

~ HABITS

The hooded seal rarely appears

on dry land. It swims in deep

water with only the top of its

head breaking the surface. At

times it hauls out to rest on a

thick, drifting ice floe.

The hooded seal is solitary

for much of the year. After the

breeding season in late March,

family group members go their

~ FOOD &: FEEDING

The hooded seal's staple diet is

fish such as cod and herring,

but it also eats squid, octopus,

and plankton. It may be able to

dive down 600 feet for food,

and remains of mussels and

starfish from the seabed have

been found in its stomach. Dur­

ing the molting and breeding

seasons, it does not feed.

separate ways. A large group

may gather again in June and

July, when the seals molt (shed)

their fur on the pack ice be­

tween Greenland and Iceland.

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

ry out an aggressive display,

inflating their hoods and bal-

loud roar. If this behavior does

not establish dominance, the

bulls fight, biting and clawing

at each other until one wins.
