Ecuador is a birdwatcher's
paradise with around 1600 species
registered and some new ones are still added to the list
every year. 22 avian
orders of the 27 worldwide with 82
families are represented in the country.
As there are 3000 species in the whole continent of South America, therefore more than half can be
already observed in this small country.
Furthermore, if you consider that in all of North America or Europe
are less than 800 species found, the diversity of Ecuador's bird
world becomes that much more amazing and
intriguing. |

Mainland
Ecuador with
its many distinct geographical and biological regions and the
Galapagos islands are home
to a wide range of birds.
Many of them show interesting features and behavioral characteristics and
we
try here to bring some of them closer to your understanding,
explaining their life styles and
habitats, where to find them in the
country and exhibiting photos of them. We start with the one bird, which inspired
already people many centuries ago and still commands awe today,
the mighty
Andean
Condor, one of the largest flying bird in the world
with a wingspan of over 3 meters. It belongs to
the
American
Vultures family, which among others include the now
rare King Vulture. In
Raptors you find descriptions of
eagles, hawks, kites and
falcons, the large group of diurnal birds of prey, well represented
worldwide and in the country. A special page is
dedicated to the
Caracaras, a
sub-family of the falcons, only found in the Americas, interesting for their
distinctive behavior.
Owls,
which are
nocturnal predatory birds,
are
also well represented in the country and found in
many habitats.
Other well known birds with representative species encountered throughout the four major regions of Ecuador are
Gulls
and
Pigeons & Doves.
Not so common and thus of interest to some
is the
Cock-of-the-Rock,
inhabiting the cloudforest regions of the
Andes and where the bright-red males gather in leks.
Other colorful birds found there are
Motmots
and
Cuckoos & Anis,
which are also found in
the lower tropical regions.
More of
our avian friends introduced here are the well-known colorful
Macaws
and the huge billed
Toucans
also encountered in the tropical regions of the Amazon or
coastal forests. There live also the
Caciques & Oropendolas,
which are experts in weaving nests suspended from
branches of tall trees. A very special bird of the Amazon is the
very distinct
Hoatzin with
its pre-historic look.
Herons
& Egrets
can be observed wading along the river banks, Pacific beaches and marshes of
the country.
Another group of wading birds
are the graceful
Flamingos,
which can be admired along the Pacific coast but mainly in the
Galapagos islands. Those
islands far out in the Pacific ocean are important breeding grounds
for seabirds like the
Boobies,
Frigatebirds,
Pelicans
and
Albatrosses.
The flightless cormorant, endemic to Fernandina and Isabela islands,
is unique among the
Cormorants
as it lost its ability to fly. Other flightless birds and which are
usually associated with the cold Antarctic waters are the
Penguins. Finally, as we started with the largest bird of Ecuador,
we end it here with
the smallest of all
birds, the amazing flying acrobats called
Hummingbirds, represented by many species, living from
sea level right up to the high glaciers. |

Mainland
Ecuador
only has 14 endemic bird species but its national
territory boasts of some important
and sensitive endemic bird areas
(as established worldwide by BirdLife)
which it shares with its
neighboring countries. Those restricted ranges have a high
number of endemic birds, ones only found in that limited area
and which are therefore important to
be protected as habitat destruction would eventually lead to
extinctions of those range restricted birds. Two of the
world's most important ones are found in the country, the
Chocσ area, comprising Western Colombia and Northwestern
Ecuador, a mainly forested low- and highland
region and the Tumbesian Region, comprising the montage
and lower regions of southwestern Ecuador and northwestern
Peru. Other significant regions are the Western Amazonian
Lowlands, East Andes slopes and Inter-Andean valleys, all
reaching also into parts of Colombia and a small part of the
Rio Maraρon region sharing endemic birds with northwestern
Peru. |

On
Galapagos, which is considered by ornithologists a separate and
distinct bird region, are encountered only 58 species of birds
but with 28 of them endemic, only
found there and nowhere else.
One of the most amazing things on the islands
is that the birds did not develop any fear of humans and therefore
you might walk among breeding colonies of
seabirds without them flying off or a
hawk might land only a few meters from you. There you also find the famous finches, which gave Charles
Darwin thoughts for
his new theory of evolution. It is believed that those
Darwin finches had one common ancestor, which arrived at the
islands by chance long time ago
and evolved then by adaptive radiation in 13
distinct species with their own
characteristics and feeding habits. One of them, the woodpecker
finch uses a tool, rare among any animals, a twig to probe in
holes of trees to catch some grub, which otherwise it would
be unable to reach with its beak. |

Birds are a class
of warm-blooded vertebrates and evolved from
some unknown dinosaur ancestor. They are relatively recent
arrivals in the animal world with the first known specie some 150 million years old. This famous fossil find
called Archaeopteryx shows both characteristics of a
dinosaur (toothed beak) and a modern bird (feathers). At the
time of the dinosaur's reign eight subclasses of aves (or
feathered dinosaurs) roamed about. Not all could fly and
feathers might have evolved primarily not for flight
purposes but for insulation or sexual display. Of those eight
sub-classes only one sub-class, the neornithes made it
through the extinction bottleneck of 65 million years ago and
carried on the dinosaur lineage to our present times. The
surviving birds radiated into many diverse forms and ecological
niches and not all took to flight. Huge tow-legged carnivorous
birds (like the 3m huge and terror inspiring Titanis in South
America) evolved on islands or island continents devoid of
mammals. Only after mammals reached those lands, did they had to
yield (?) and became extinct. Most birds as known today evolved roughly 5-10 million years ago. |

Avian
Classification |
| |
|
This class of animals has around 10 000
species worldwide. Below you find a traditional classification of the bird world with 29 avian orders, based mostly on their internal anatomy.
New fossil finds and advances in behavioral studies
and new techniques in DNA tracing and biochemistry
question often those classifications and quite a few
more tables exist which try to
group our feathered friends. |

The most important features of modern birds which distinguish them from other animals
are their feathers, toothless bills and vocals. Their most important trait is that all of them can fly or
like in the case of some birds, like the ostriches and kiwis could so
in their recent past. Adaptations to flight greatly influenced their evolutionary process
till they became the most efficient flying vertebrates. To achieve that,
profound changes had to take place, like forelimbs fusing into wings, bones
becoming
light and hollow, feathers covering the body and the wings. Flight also
enables them like no other animal to move around freely
without any major geographical restrictions and large
migrations of birds take place every year. One bird, the
Arctic Tern, covers every year 50 000km moving from the
Arctic to the Antarctic continent.
Like their reptile ancestors, birds lay eggs for reproduction but
in contrast all bird eggs are hard-shelled. Having this kind of
external reproduction has the advantage that the female bird is not
hindered by extra weight, which would make flying difficult or
impossible. After the young hatch, the parents take care of their offspring feeding
them till they can survive on their own. Sexual maturity is reached
quickly. Birds are highly adapted animals and are found on all
continents and in all ecosystems from polar regions to the
driest deserts and feeding on any
possible food items. |
