Physiology/Morphology
There
are approximately 40 known species of toucans. They are classified
in the same genealogical family as the toucanet -- a smaller
version of the toucan -- and the aracari -- which has a differently
shaped beak, and is smaller than the toucan.
The toucan's
beak is its most prominent feature, sometimes as long as its
body. Toucans use their beaks for picking berries, for maintaining
their territory and for attracting females' attention. The
insides of their beaks are shaped like honeycombs, making
them strong yet lightweight.
The toucan's
body is anywhere from 13 to 25 inches long, slightly longer
than their beaks. Their bodies are usually colored with black,
white, red, yellow, blue, and green feathers. The toucans
are poor fliers because of the size of their beaks, and they
rely on hopping from branch to branch in trees.
While
different species of toucans vary somewhat in longevity, the
average lifespan of a well cared for toucan is at least ten
years, and they can live to be approximately 15 years old.
The toucanets live a few years more, but the aracaris have
shorter life spans.
Only a
few species of toucans are sexually dimorphic -- male and
female have different characteristics. An avian vet can determine
the gender of the toucan by DNA testing -- in which a blood
or feather sample is tested -- or by probing the bird for
sex organs.
The
Toucan at Home
Toucans,
as well as other birds of the same species, are indigenous
to tropical America. They are found ranging from southern
Mexico throughout South America and its neighboring islands.
By nature,
toucans are rain forest dwellers, and live high among the
treetops, as high as 9,000 feet. They also tend to be solitary
creatures, avoided by other bird species since the toucans
fight and kill them if provoked. It is not advisable to house
different species of toucans together, as they will kill each
other. Even introducing two birds of the same species should
be done cautiously.
Food
A toucan's
diet is fundamental to its health, and should be meticulously
regulated. Toucans are softbills -- their diet is primarily
fruit. In the wild, toucans consume berries, eggs, and sometimes
small animals. During the mating season, they ingest a large
amount of insects for protein. They get most of the water
and moisture they need from the fruit they eat.
Caged
toucans do not need the same variety in their diets as toucans
in the wild, as long as they are fed fresh fruit -- which
constitutes 50 percent of their diet -- and specially formulated
softbill food, available at most pet stores. Since these foods
are specially formulated, it is not necessary to supplement
them with vitamins. Excess nutrients could potentially kill
the toucan. Breeding toucans can be fed crickets for extra
protein in addition to this diet.
An all-seed
diet is to be avoided. Seeds kill toucans because their digestive
tracts are not designed to dissolve the seeds. The toucan
would starve to death if fed an all-seed diet.
Most fruits
are relatively safe for the toucan to eat, but avoid fruits
that have an excessive amount of citric acid because they
can ulcerate stomachs, causing digestive problems. The most
common citric fruits are grapefruit, orange, lime, pineapple,
and tomato.
One of
the most preferable fruits that the toucan eats is papaya.
Grape, cantaloupe, apple, and banana are ideal fruits to be
fed to toucans.
If giving
the toucan nonformulated treats and foods, be careful of the
amount given. Feeding the bird too much will cause it to overeat
and get sick. Excess, uneaten food quickly rots and spoils
and can kill the bird with bacteria and toxins if eaten.
Toucans
obtain most of the water they need from the fruit they eat.
They prefer to use their water supply for bathing. However,
make sure a sufficient amount of cool, clean, fresh drinking
water is always available.
Health
Problems
The most
common disease that affects the toucan is hematochromatosis
-- iron storage disease. It occurs when the liver accumulates
too much iron, eventually poisoning the bird. At this time,
the only method to identify the disease in a living bird is
through liver biopsy. Presently the only way to treat hematochromatosis
is through phlebotomy, removing a certain amount of blood
from the bird to decrease the amount of iron in its bloodstream.
The best
way to avoid hematochromatosis is through prevention. Read
the labels of all foods, and do not feed the toucan any red
meat. It is not essential to a healthy diet, and has no nutritional
value for them. However, do not remove all the iron from the
toucan's diet.
Iron content
is expressed in parts per million (ppm). An acceptable amount
of iron in the kibble/softbill food is 120 ppm. However, some
products that claim to be low in iron also contain propylene
glycol, which will kill the toucan.
When toucans
are exposed to infected mice or feces, they can contract bacterial
diseases, including E. coli, salmonella, and yersinia. The
first two are spread by infected or spoiled food, or feces.
Yersinia -- pseudotuberculosis -- is spread by mice feces.
All of these diseases are easily treatable.
Housing
When first
bringing the toucan home, you should keep a watchful eye on
it for several days, since it has undergone a lot of stress
on its journey. It should be kept in a cage that closely approximates
in size the one it was previously housed in to lessen this
stress. The cage may be kept outdoors if the weather permits;
otherwise, keep the bird indoors in its cage until signs of
stress are no longer apparent.
Toucans
require lots of room so that they can stretch their wings
and run around. Whether housing the toucan indoors or outdoors,
the bird should always have a very large cage, at least the
size of a large parrot cage. The size of a good flight cage
is 4 feet by 8 feet by 4 feet for smaller birds, and 8 feet
by 12 feet by 6 feet for an average-size toucan. Another option
is to build a cage, or have one built. Make the cage or aviary
very tall, as toucans are most comfortable at higher elevations.
Plan on
buying or constructing a cage or aviary of these dimensions
because it is not a good idea to clip the toucan's wings.
Its beak size does not allow it to maneuver and climb up the
sides of the cage as most birds do, and it will have difficulty
getting around the cage.
Take into
consideration also that toucans can be very messy. If housing
the toucan indoors, it is recommended that the surrounding
cage bars be covered with durable plastic or plexiglass sheets.
This will contain the mess while not detracting from viewing
the bird.
If the
toucan is to be kept out of doors, the ideal time to introduce
it to the outside is in the morning as early as possible.
It will familiarize itself with the location of food, water,
and perches, and gradually relax in its new home.
Do not
leave the toucan out of doors when it is raining, snowing,
or when the temperature exceeds 90 degrees Fahrenheit. Once
the bird has adapted to its new environment, it is reasonably
tolerant of weather extremes. This adjustment is gradual,
though, and the toucan should be kept outside for spring,
summer, and autumn first so that it can gradually acclimatize
to the cold winter weather.
When the
weather is cooler, another necessity for housing the toucan
out of doors is a heat box. Toucans' toes can easily become
frostbitten. The birds sit in front of or stand on these boxes.
They are relatively easy to construct with plywood and a 250
watt heating lamp. Place the heating box about 8 feet from
the ground, and put it near a perch. Make the boxes available
to the toucans when temperatures fall below 40 degrees Fahrenheit.
Reproduction
and Rearing
The breeding
season is generally from March to May. Do not breed the toucans
during the winter -- eggs will be unhealthy and the young
will be sickly -- or in the summer -- it is too hot for the
parents to raise young successfully.
To raise
their young in the wild, toucans make a nest in hollow tree
trunks, digging out a hole with their powerful beaks. These
nests are usually one or two feet deep. Lots of room should
be allocated for the breeding pair, at least the size of their
normal cage or aviary. Give them a feeling of security and
privacy by making three of the four walls solid.
The female
toucan lays three to four pure white eggs, and incubates them
for 15 or 16 days; both parents incubate. Newborn toucans
are nidicolous, or nest-reared. The babies are blind and naked
at birth, and their eyes open after about three weeks. They
are helpless and unable to leave the nest for about eight
weeks, dependent upon both parents to feed them.
After
this, the young toucans can care for themselves. The birds
begin to leave the nest after 40 to 50 days, depending on
size. During this time, supplement the parents' diet with
live crickets. Also, soak their kibble/softbill food in water
for the entire time the chicks are being fed.
If the
parents refuse to rear their young, it becomes necessary to
hand raise them. This is also necessary if the owner wishes
to have a tame bird. Small amounts of food should be offered;
wait until the bird has completely swallowed one bite before
offering another, making sure that its mouth is totally empty.
Feed each baby 10 to 15 percent of its body weight per six
to ten servings per day. Feed them five to seven times a day.
There
are several hand-feeding formulas available. Mix some strained
papaya human baby food with this, omit adding additional vitamins
or minerals.
Cost
Unfortunately,
toucans are quite expensive; toucanets and aracaris are less
expensive. The toucan varies in price from dealer to dealer,
and from species to species. The toco toucan, Ramphastos
toco, can cost as much as $6,000. Toucanets and aracaris
can be as inexpensive as $800. Some breeders charge extra
for hand raising the birds. If purchasing a toucan as a pet,
it is highly recommended that a hand-raised bird be purchased.
This may cost more, but it ensures a high quality pet that
is likely to live a longer life.
House
Pets
For the
true and dedicated bird enthusiast, the toucan, or one of
its close relatives, is a wonderful and very enjoyable pet.
They are beautifully colored and very animated, providing
hours of enjoyment for any owner. However, these birds are
not for people with limited amounts of room or time. Their
diets must be strictly maintained, or the birds will become
sick and die.
The basic
things to remember when raising or breeding toucans are: a
low iron diet, a moderately warm climate, a suitable nesting
log, a suitable cage or aviary, and a healthy compatible pair
for reproduction.

have access to the Internet, check out the following web sites
for additional information: Emerald
Forest Bird Gardens, Riverbanks
Zoo and Garden, and The
Toucan Palace.
While
it may seem more trouble than not, toucans are great pets
which are very fulfilling to raise and to breed. For those
with any of the above mentioned restraints, it is best to
consider another easier to care for pet. Do not miss out on
any opportunity to experience the joy of toucans. You will
not be disappointed.

A reader
writes in response to this article:
"I
picked up the December issue of Bird Times to check
out the article on toucans. I was glad to see that the article
mentioned that these birds require an inordinate amount of
time, space and effort and that they are not a good choice
for most bird enthusiasts. I would like to add however, for
those few individuals who have the dedication and expertise
to work with toucans, that we have a responsibility to the
conservation of toucans in the wild as well as their health
and success in captivity. Please obtain only close-ringed,
captive-hatched juvenile birds and only from a reputable breeder.
Please assume (regardless of what the seller may communicate,
or the apparent tameness of the bird) that an adult or nearly
adult bird without a closed ring is a wild-caught bird."
Thanks
for your advice! And we're glad you enjoyed the article and
hope this recommendation helps any other readers that are
interested in owning a Toucan.
