is the common name for
the well-known birds with
the large
and colorful beak found only in
the Americas, from southern Mexico to
northern Argentina. They belong to
the order of Piciformes and comprise the family of
Rampastidae with 6 genera
and 38 species. In
Ecuador are 19 species in 5
genera present,
inhabiting
the lowland and higher tropical forests of the country. |

Toucans most
prominent feature is of course its colorful and large bill
(bill of the White-breasted Toucan is shown, picture taken in Baños Zoo)
which in some species exceeds half the length of the bird's body. Although
that long it is lightweight because it is hollow. Inside the bill is
a long and narrow tongue, which is
frayed on the sides to increase the sense of taste and runs the whole
length of the beak. They
eat mostly fruits and can easily manipulate the berries at the tip of
their bill. |

Toucans are found in tropical cloud and rainforests
on both sides of the Ecuadorian Andes. They feed primarily on fruits
but supplement their diet with worms, insects, eggs and hatchlings, small birds and
reptiles. They
range in sizes from 18cm to 63cm,
with the
largest toucans being those of the genus Ramphastos,
considered the classical toucans, living in the lower tropical rainforests. Mountain-Toucans,
which are a little bit smaller,
inhabit more higher elevations. The
medium sized Araçaris
are found in the lower regions with some ranging higher
up. The smallest
are the green
toucanets which are found both
in lower
and higher
lying forests. |

Five genera of toucans are found in the
country, Ramphastos, Andigena,
Pteroglossus,
Aulacorhynchus (photos from left to
right) and Selenidera
(not shown). |

Toucans
do not build nests but use the hollows of trees or abandoned nests
of other birds. Females lay 2 to 3 glossy white eggs
and both, male and female incubate. The young
are born completely naked without any down
and blind for the first 3 weeks. Both parents feed the chicks
for about 7 to 8 weeks till they leave the nest. As toucans
spend all their time on or near trees, they are affected by the
ongoing deforestation in the country and some species
are endangered. They are also caught in
order to be
sold as mascots and pets due their beautiful bills
or natives use their feathers in ornaments and also like
to eat their meat.

The
Pale-Mandibled Araçari is one of fourteen endemic
bird species of the Ecuadorian mainland and the only
endemic toucan in the country. Its range is from western
Esmeraldas to western Guayas, being found mostly below 1000m but
ranging in some regions up to 1600m as it does in the Mindo
region (where photos were taken by Christian Storch). As with all toucans, being forest dwellers,
deforestation affects their numbers. |
