 Comparison of Immediate Skin Test Reactions in Clinically Normal and Self-mutilating Psittaciformes   (Site not responding. Last check: 2007-08-19)
Forty one Psittaciformes with no evidence of self-mutilation were subjected to intradermal skin testing along the apteria between the sternal pterylae using saline, histamine and aqueous allergen extracts of rye grass, wheat, canary, oat, maize, grain mill dust, D.
Psittaciformes from a local pet shop were examined for evidence of self mutilation in December 1997 and January 1998.
The highly significant difference in the proportion of self-mutilating Psittaciformes (93%) showing at least one wheal reaction in response to intradermal skin testing against nine environmental allergens compared with control birds (2%) could suggest that allergens may play a role in the development of self-mutilation.

Stem group psittaciforms are known from material that comes from the Early Eocene London Clay Formation, England (Dyke and Cooper, 2000), as well as articulated material from the Middle Eocene formation at Messel, Germany (Mayr, 2002).
An isolated record of a lower jaw of a psittaciform was reported from the Cretaceous Lance Formation, Wyoming (Stidham, 1998).
This edentulous jaw fragment is allocated to Psittaciformes based primarily on the k-shaped pattern formed by the neurovascular canals and the deeply concave symphysis (Stidham, 1998).

 Bird Information: Psittaciformes- the parrots
The Psittaciformes have 216 species, that are grouped into 82 genera and then further broken down into subfamilies.
The lorys, a member of the subfamily Loriinae, is a bird which has brilliant coloring, small beak and brush like tongue, permitting the bird to collect pollen and nectar from many flowers including its favorite, the eucalyptus.
Perhaps the most familiar form of the Psittaciformes is found in the family of true parrots, psittacinae.

The HI titers that develop in Psittaciformes may be low with Amazon parrots and Psittaculidae, having average titers of 1:8 to 1:64, while cockatoos may have titers of 1:320.
Vaccines administered to Psittaciformes in the drinking water have been shown to be ineffective.
PMV-2 infections are more severe in Psittaciformes, particularly in African Grey Parrots, where emaciation, weakness, pneumonia, mucoid tracheitis and mortality are common findings.64 The Bangor isolate from finches was proposed as a cause of death in a Blue Waxbill.

The evolution of the spindlin gene in birds: sequence analysis of an intron of the spindlin W and Z gene reveals four major divisions of the Psittaciformes.
This paper describes the phylogenetic relationships between a number of Psittaciformes as derived from the sequences of the third intron of the Z-chromosomal and W-chromosomal spindlin genes.
The results support a Gondwanan origin of the Psittaciformes and the suggestion that paleogeographic events were a major force in psittacine divergence.

 Bursaries for the Second Biennial Meeting of The Systematics Association   (Site not responding. Last check: 2007-08-19)
Preliminary cladistic analyses show that the psittaciform stem-group consists of fossil taxa known from the early Tertiary of Europe that form successive outgroups to the sole Recent family within the order, the Psittacidae.
Within a monophyletic Psittaciformes, three major clades are apparent: the Quercypsittidae from the Eocene of France, a clade consisting of fossil taxa from the Eocene of Germany and the UK and the Psittacidae.
Psittaciform monophyly is supported by, amongst other characters, the presence of a prominent coronoid process of the mandible and trochlea for metatarsal IV completely laterally retroverted (zygodactyl foot).

 Healthspa - Proventricular Dilatation Disease: A Viral Epornitic
As it became apparent that the disease occurred in psittacines other than macaws, a more general terminology was used to describe the syndrome, including proventricular dilatation syndrome, psittacine proventricular dilatation syndrome, psittacine wasting syndrome, proventricular hypertrophy and proventricular dilatation disease.
Proventricular dilatation disease is used to describe an inflammatory response characterized by the accumulation of lymphocytes and plasma cells in the nervous system, especially the nerves that supply the muscles in the proventriculus and other digestive organs including crop, ventriculus and small intestine.
Given the severe nature of PDD and its apparent ability to affect a wide range of bird species, the importation of psittacine birds, or their eggs, into any region with indigenous Psittaciformes must be considered extremely dangerous.

PARROT [parrot] common name for members of the order Psittaciformes, comprising 315 species of colorful birds, pantropical in distribution, including the parakeet.
Parrots have large heads and short necks, strong feet with two toes in front and two in back (facilitating climbing and grasping), and strong, thick bills, with the larger hooked upper mandible hinged to the bones of the head.
Care should be exercised, however, by selecting birds with known histories, since even apparently healthy birds may be carriers of infectious psittacosis, or parrot fever.

The parson's nose is reduced and there are special powder dunes which produce a fine mealy dust to conserve the plumage.
The feathers of the Psittaciformes contain a specific group of pigments, called Psittacin which in combination with others lead to the beautiful colors that are found in these birds.

The order Psittaciformes (Parrots, Macaws, Cockatoos and Lories) occur on all continents and many islands across the world.
I propose to generate a review of the morphological evidence supporting the major phylogenetic subdivisions within Psittaciformes on the basis of cladistic analysis.
As is standard in phylogenetic analyses, osteological characters will be formulated and defined when features are considered to show variation between (but not within) the taxa under consideration and partionable into two, or more, discrete states.

This empiric trial in five different species of psittaciformes showed that subcutaneous injections of perphenazine seems to be safe, at least concerning the clinical symptoms observed after injection.
Even the wide dosage range of 1,25 to 8,7mg per kilogram bodyweight used in the trial indicate the drug as useful for treatment in combination with a thorough diagnostic evaluation in each individual case.
The application of perphenazine is not a complete solution, but might be a very effective support in handling different psychological disorders in psittaciformes, but still it needs great care to use it, because it is not registered for psittaciformes.
