The parrots have the curved, strong and ganchudo tip. The wings usually
are short, cleared, but the tail can be enough long. Some species, like
kakapo of New Zealand, are lost the faculty to fly (it sees nonflying
Birds). The fingers of the legs present/display a disposition
zigodáctila, that is to say, two directed and two forwards backwards.
They
walk clumsily on the ground, but they are trepadores excellent and they
often use the tip as a hook to move between the branches. Most of the
parrots they have heavy and muscular a language, that use with great
ability to extract seeds and grains, their main power supply, in
addition to leaves and fruits. In the group of the small parrots, the
language is longer and finishes in bristles as a brush, thanks to which
they liban the nectar and they polen of the flowers.
The colorful one of the plumage of the parrots is
very variable. Although a great majority is green, others are blue,
yellow or red. Between the most showy species it is the small parrot
rainbow, of blue head, green back and yellow-reddish chest. The
cockatoos, generally, are white or black, with I touch of yellow, red
or pink.
Most of the parrots nest in holes of the
trees, but some species use termiteros, cracks on the rock or tunnels
that construct in embankments. The Argentine cotorrita, also called
cotorra monk or catita, constructs a great nest formed by woods in the
glasses of the trees. Most of the species they raise by pairs, with
some exceptions, like already mentioned cotorrita Argentinean, who
nidifica in communal nests.
The females of the
parrots usually put between two and five eggs and the chicks are born
very little developed, naked and completely blind.
The
capacity of many parrots to imitate the human voice and other sounds is
one of the reasons for its popularity like mascots. The best imitador
is papagayo gray African or dark-brown yaco, a bird of about 30 cm in
length, with the gray plumage, except the tail, that is red. Studies
made with this species have demonstrated that it can be as intelligent
as the dolphins and primates.
The demand of the
commerce of cage birds and the loss of habitat are the main causes of
which many species of parrots are considered like threatened species.
In most of the countries the capture, export and import of parrots
strictly are regulated, but every year thousands of birds they are sent
to Europe and to North America, as much legal as illegally, and many of
them not even survive the trip.
One of the
possible solutions to this problem would be the exclusive
commercialization of those species that have been bred in captivity.
Another added problem is the one of those saved species of the
captivity that finish by asilvestrar themselves in the receiving
countries. This it is the case of cotorra of Kramer, original bird of
Asia and Africa, green color emerald, with very long tail and alive red
tip. One is locally in some countries of Europe, among them Spain.
