Complete mitochondrial genome of chestnut-fronted macaw (Ara severus, Psittaciformes)

Mitochondrial DNA. Part B. Resources, 2017
Six genera from Arini tribe form a morphologically diverse group named macaws, which differ from other Arini in the presence of bare facial area. Macaws are further distinguished by the bare face pattern, plumage colouration and body size.

Are anti-ganglioside antibodies associated with proventricular dilatation disease in birds? [PDF]

PeerJ, 2017
The identification of Parrot bornaviruses (PaBV) in psittacine birds with proventricular dilatation disease (PDD) has not been sufficient to explain the pathogenesis of this fatal disease, since not all infected birds develop clinical signs. Although the

CITES Appendix III: An underused tool for international wildlife trade regulation

Conservation Science and Practice, EarlyView.
Appendix III of CITES allows Parties to unilaterally extend domestic species protections to international trade, yet it remains vastly underused, covering just 1.3% of listed species. Drawing on the complete historical record since 1975, we show that Appendix III is most effective for endemic species and functions as a highly successful staging ...

Seasonality and plasticity in the use of native and introduced plant resources by a large forest parrot

Ibis, EarlyView.
Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.

Age Difference, Not Food Scarcity or Sibling Interactions, May Drive Brood Reduction in Wild Scarlet Macaws in Southeastern Peru

Diversity
Avian brood reduction was initially thought to be driven by insufficient food supply. Now it is more commonly considered a consequence of asynchronous hatching and resulting siblicide, direct filial infanticide (where parents kill specific chicks) or ...

Skull morphometric characters in parrots (Psittaciformes) [PDF]

Ornis Hungarica, 2020
Abstract Parrots (Psittaciformes) are a unique and diverse avian group and vary tremendously in size, shape, and colour. Mainly distributed throughout the tropics and subtropics, most species of parrots are largely or exclusively arboreal with several exceptions.

A Cross‐Sectional Study on Parakeets Feeding and Housing Practices in Italy

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Italy has one of the largest companion bird populations in Europe. This study aimed to investigate feeding and housing practices among Italian parakeet owners. An online questionnaire was distributed, yielding 433 voluntary responses. Participants were classified as hobbyists (HBY; ≤ 13 birds owned) or breeders (BRD; > 13 birds owned) to ...

Mitochondrial DNA. Part B. Resources, 2017
Arini tribe with 19 genera is the most diversified tribe of neotropical parrots. Six of them are classified as macaws and nine as conures. The presence of bare facial area distinguishes macaws from conures and other members of this tribe.

First isolation of Mycobacterium genavense in a blue headed parrot (Pionus menstruus) imported from Surinam (South America) to the Czech Republic: a case report

Veterinární Medicína, 2010
In 2005 a Mycobacterium genavense infection was diagnosed in one blue-headed parrot (Pionus menstruus) imported from Surinam (South America), the first such incidence in the Czech Republic. The bird died suddenly. Histopathological examination revealed a

Variation in parrot jaw musculature

The Anatomical Record, Volume 309, Issue 9, Page 2519-2533, September 2026.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,
