PHYSICAL
CHARACTERISTICS:
Toucans get their name from ‘tucano’ given
to them by the Tupi Indians of Brazil. The largest species, the
toco toucan, is about 25 inches (64 cm) long. the smallest toucan
is the aracar toucanet which is only about 14 inches (36 cm) long.
Toco toucans have the largest bill of any toucan. The toco toucan
is mainly black, with white on the throat and upper breast. The
bill is orange crimson, fading to greenish yellow. There's a large
black oval blotch near the tip of bill, and a narrow black line
at the base. The most prominent feature of toucans are their bills,
which are much lighter in weight than they appear. These large,
boldly colored bills give them a distinctly out-of-balance appearance.
A thin horny outer sheath encloses a hollow which is crisscrossed
by many thin, bony, supporting rods. It has serrated edges which
help to tear off pieces of larger fruits. Within the bill, the
tongue is bristly and narrow, resembling a feather. It reaches
to the tip of the bill.
The toucan's large bill enables it to perch inside the crown
of a tree, where branches are thicker, and reach far outwards
to pluck berries or seed from twigs too thin to bear their weight.
Seized in the tip of the bill, food is thrown back into the throat
by an upward toss of the head.
The varied patterns of toucans' bills may help these birds to
recognize each other or attract a mate.
DISTRIBUTION and HABITAT:
Toucans are found in tropical and subtropical forests in South
America;, mainly in Brazil, Paraguay Argentina, and Bolivia. There
are about 40 different species of toucans.
BEHAVIOR:
Toucans are moderately gregarious and fly in straggling flocks,
one after another, rather than in compact bands, like parrots.
They prefer to remain high in trees, where they hop from branch
to branch. They bathe in pools of rain water in hollows high in
trunks and limbs. They offer food to their companions and, perching
well apart, preen them with the tips of long bills.
Toucans are playful birds and often engage in various games.
DIET:
Their diet consists mainly of fruit but includes insects, an occasional
lizard, eggs and nestlings of smaller birds.
REPRODUCTION and GROWTH:
Toucans nest in holes in trees. The nest chamber is never lined,
but the 2-4 white eggs rest upon a few chips at the bottom, or
upon a pebbly bed of regurgitated seeds of various sizes.
Parents share incubation and are, for birds of their size, impatient
sitters, rarely remaining at their task for more than an hour
and often leaving their eggs uncovered.
After about 16 days of incubation
the nestlings hatch blind and naked, with no trace of down on
their pink skins. Nestlings are fed by both parents, with increasing
quantities of fruit. The feathers of the small toucanets do not
begin to expand until they are nearly four weeks old. Parents
will care for their young for about 8 weeks; however, small toucanets
may fly from the nest when 43 days old.
