Meet the Macaws
Macaws are the largest parrots in the world.
They’re beautiful birds,
often showing off brilliantly colored feathers.
Most macaws live in Central and South America. Macaws are part of the parrot
family. They are related to all parrots but are less closely related to parakeets
and cockatoos.
The blue-throated macaw is critically endangered. The small number of wild
blue-throated macaws live in eastern Bolivia. The birds are illegally captured
and sold as pets all over the world.

Sadly, these colorful, intelligent creatures are in trouble. Some species
of macaws are extinct already.
Many more are endangered,
which means they could become extinct. Only about one million macaws are still
living in the wild. A million sounds like a big number, but only three species
(blue-and-yellow, red-and-green, and scarlet macaws) make up most of it. Most
species have very few members left. For example, there are thought to be fewer
than 100 blue-throated macaws left in the wild.
At Home in the Rainforest (Mostly)
The red-fronted macaw is from central Bolivia and is the smallest of the
large macaws. From head to tail it is only .6m (24in.) long. The rare birds
were not recognized as a definite species until the 1970’s.

Most macaws live in South and Central
America. However, at least two species—scarlet macaws and military
macaws—can be found in Mexico as well. Most macaws live in tropical
rainforests, where they make nests in
holes in trees, but some live in other habitats.
Red-fronted macaws live in semi-desert regions, in holes and cracks in cliff
faces. The yellow-collared macaw lives in grasslands.
Even in the rainforest, different macaws prefer different homes. Red-bellied
macaws are found in swampy areas. Scarlet macaws prefer the lowlands. Most
macaws are not very adaptable.
When their preferred habitat is damaged, their breeding habits
and health can be seriously affected.
A Parrot Pair to Last a Lifetime
Red-and-green macaw chicks can't see and need a lot of care and protection
when they first hatch. The chick's eyes don't open until it is about 15 days
old. This chick is about one-month-old with eyes wide open and already growing
its colorful sheath feathers.

Fossils of
parrot-like birds have been found in Europe dating back as far as 50 million
years ago, but scientists don’t really know much about how modern macaws evolved.
They do know a lot about how macaws live and breed today. For instance, they
know that most macaws mate for life. They form breeding pairs called pair bonds
that live together, groom each
other, and share food.
Macaws lay eggs once
a year. Breeding seasons generally begin in late fall or early winter. In most
cases, two or three eggs are laid at a time. Females keep the eggs warm while
the males find and bring back food. When the eggs hatch, both parents go “shopping” for
the family. The newly hatched chicks are helpless until they grow their flight
feathers and become fledglings. Then they can leave the nest and join the flock.
And It’s a Long Lifetime
Macaws in captivity can
typically live longer than macaws in the wild. Still, macaws have long life
expectancies, ranging from around 40 years to around 80 years—or even
beyond 100! Smaller macaws have shorter lifespans.
Some species live in small family groups of only a few members, but some live
in flocks of dozens of macaws. Even when flying with a flock, pair bonds fly
close together, wingtip-to-wingtip.
Macaws are social birds and enjoy playing, grooming and calling out to macaws
of the same species. Several different flocks of macaw species are roosting
in the forest canopy.

Macaws are large, powerful birds specially
adapted to their world. The largest ones, hyacinth macaws, are approximately 1
meter long from beak tip to the end of their tail. The smallest, red-shouldered
or Hahn’s macaws, might be only 30
cm long.
Friends, Not Fighters
Macaws are very intelligent and sociable
animals. Courting macaws preen and “kiss” each other—trading
gentle beak-to-beak bites. They are curious and playful, spending a lot of
time with friends and family. They can also be really noisy. Like other parrots,
pet macaws can imitate human speech. They explore, investigate interesting
objects with feet and tongues, and chew things to keep their beaks in shape.
They also take frequent baths.
Although they have strong beaks and legs tipped with sharp, grasping claws,
macaws are not fighters. They will deliver a bite if necessary, but would rather
fly away than take on a predator.
Let's Hit the Drugstore before Dinner
When macaws eat, they usually stand on one foot. With their other foot,
and the help of their beak and strong tongue, they can open almost any nut
or fruit. They can easily grasp different kinds of object with their feet
and toes.

Macaws are herbivores.
They eat primarily seeds, nuts, and fruit. Using their impressive beaks, they
have no problem opening even the toughest seed. First they scratch a thin line
with their beak’s sharp point, and then they shear the seed open. But
inside some of those seeds are poisonous chemicals. How can macaws eat the
seeds without getting sick or dying? They visit clay licks—the rainforest’s
natural “drugstores.”
The Amazon rainforest has more than 100 of these special clay- and mineral-rich
areas along riverbanks. Throughout the mornings, hundreds of macaws will stop
by to lick and nibble at the clay. Scientists and other macaw experts believe
that chemicals in the clay neutralize the toxins in
the seeds. In this way, the macaws keep themselves healthy.
Easy Pickings
Macaws eat fruit, nuts and seeds but some macaws eat only one kind of nut.
Macaws have no problem splitting open the hardest nut shells with their sharp,
strong beaks. A human would need to use a hammer to open a palm nut.

When macaws eat seeds, they destroy them. For this reason, they are sometimes
referred to as seed predators. When many other animals eat fruits,
the seeds pass through their systems undigested. In this way, seeds are distributed
to new locations where plants then grow. Macaws take advantage of this when
they forage in cow pastures. By picking palm nuts out of the cows’ droppings,
they get an easy snack--one whose tough shell has been removed by the trip
through the cows’ digestive systems.
Red Alert: Macaws in Danger
Hyacinth macaws are the largest flying parrots. They fly in small flocks
or in pairs and stay with one mate for life.

Macaws face two major threats: habitat destruction
and the pet trade. Places where macaws live are being destroyed mostly as a
result of deforestation.
More than 18,000
square kilometers of Amazon rainforest are cut down every year. That’s
an area larger than the state of Connecticut in the United States! So many
macaws have been captured and sold into the pet trade that this has become
a serious problem.
According to the World Conservation Union (sometimes called the IUCN), an
organization that prepares a yearly “Red List” of species in danger,
macaws are in big trouble. Five macaw species are already extinct, and nine
others are endangered, including the hyacinth macaw.
Helping Macaws
Given their beauty and appeal, it’s not surprising that macaws figure
in the mythologies of
peoples of Central and South America. In Mayan mythology, the sun god was represented
by a macaw, which is a natural role for a bird with such brilliant feathers.
But what can people do now to help these magnificent creatures?
The macaw shows up in many different forms of ancient Mayan art and artifacts
such as painting and sculptures. This Mayan artifact shows a king or ruler
wearing a macaw headdress.

One of the most important steps is to establish and protect conservation areas,
safe zones for macaws to live freely and in peace. This sounds simple, but
it’s expensive. Rainforest land is valuable. Many people want it for
the resources it
produces. However, when conservation groups pool their money and buy the land,
they can set it aside legally so it won’t be logged and
destroyed.
Of course, spreading the word about macaws and their rainforest homes is another
great step. The more people who understand that macaws are threatened in the
wild, the more people can help.
