parrot or Psittaciformes are
an order of tropical birds known, for example, under the generic terms of
parrots, parakeets, lories or conures, these terms also referring more
specifically to certain species. They possess very marked and fairly
homogeneous characters which make it possible to identify them easily.
Of recognized
intelligence, some species are capable of remarkable vocalizations and imitate
the human voice. Because of these characteristics and the shimmering colors of
their plumage, many species are raised as companion animals, some of which are
rare and protected, are subject to significant trafficking.
On the zoology of
these species, see also Psittacidae. On parrots as pets and in culture, see
Perroquet.
haracteristics
Morphology
They are sturdy
birds with big heads and a squat neck, small to large (8 to 100 cm).
Their beak is very
recognizable, short, thick and powerful, curved and articulated. The maxilla
and the jaw are fixed to the hinge of the skull, which offers the possibility
of an important and powerful vertical movement, especially as the musculature
of the mandibles is highly developed. However, as with some other species of
other orders such as flamingos, the beak is not attached to the skull. Unless
otherwise noted, the inner face of the jaw tip is lined with striated strips.
All Psittacidae, except the Psittrichas of Pesquet, use their beaks in the same
way to extract the seeds from their gangue. The seed is held between the
mandibles and the lower mandible crushes the gangue and the tongue extracts the
seed24. Their beaks grow continually, which encourages these birds to maintain
it by using them. At the base of the beak is the wax, generally naked, which
surrounds the nostrils. The tongue is also very muscular and allows them to
place the seeds to break so as to have more power. Among the Loriinae, also
nectarivores, the tip of the tongue has a kind of grater.
Each eye is
independent. They have a very mobile neck which allows them a wide field of
vision. Their zygodactyl legs, logical for birds most often arboreal, are
short.
Many species bear
plumage in exuberant colors. However, the Psittacidae do not synthesize blue or
green pigments, but it is thanks to the Tyndall effect, an optical phenomenon,
that some species have feathers of these colors. Cockatoos have a crest of
moving feathers on the top of the head that can be lifted or retracted. Most
species have little or no sexual dimorphism, Alisterus scapularis and some
other species making exceptions. The most reliable method of sexage is genetic
sexing.
The smallest of
these living Psittacidae species is the Pygmy Parakeet Micropsitta pusio with
an adult weight of 10 g and a size of 8 cm. The largest living species of
Psittacidae is the hyacinth Macaw which measures one meter, including the tail.
Some species are considered more atypical than others, such as the Great
Eclectus whose marked sexual dimorphism is an exception, the Kakapo that does
not fly, or the Kaka, Kéa and the Cockatoo nasic for the shape of their beaks,
or quite simply by their appearance as the Black Cockatoo.
diseases
Due to
domestication, the diseases of this family are well known. The spread of these
diseases is accelerated by transport. Ornithosis, more specifically named
psittacosis for this order is a most common respiratory disease. The beak and
feather disease or proventricular dilatation are emergent diseases that are
quite specific to Psittacidea. Some diseases may also be linked to stresses
such as chronic picking. These birds are also prey to many external or internal
parasites.
