Hindlimb myology of the monk parakeet (Aves, Psittaciformes)

Journal of Morphology, 2014
ABSTRACTWe studied the hindlimb myology of the monk parakeet (Myiopsitta monachus). Like all parrots, it has zygodactyl feet enabling perching, climbing, hanging, moving easily among trees, and handling food. Muscles were described and weighed, and physiological cross‐sectional area (PCSA) of four flexors and one extensor was calculated.

Liposarcoma in a Common Quail (Coturnix coturnix): A Case Report

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
A well‐differentiated liposarcoma was identified in a common quail near the uropygial gland. Diagnosis was confirmed through histopathology ABSTRACT Introduction Liposarcoma is a rare malignant soft tissue tumour and it has only been occasionally reported in birds such as goose, parrot and falcon.

Diversity in olfactory bulb size in birds reflects allometry, ecology, and phylogeny [PDF]

, 2015
The relative size of olfactory bulbs (OBs) is correlated with olfactory capabilities across vertebrates and is widely used to assess the relative importance of olfaction to a species’ ecology.

Avian Lifespan Network Reveals Shared Mechanisms and New Key Players in Animal Longevity

Aging Cell, Volume 24, Issue 9, September 2025.
In this work, we found that birds with similar lifespans exhibit convergent evolution in specific genes, suggesting that shared evolutionary pressures shape the genetic basis of lifespan similarity across species. By investigating protein–protein interactions across genes evolving convergently in long‐ and short‐lived species, we identified a network ...

Free Flight Training as a Tool for Psittacine Reintroductions

Birds
As habitat loss and other threats accelerate, ecological restoration and reintroduction science are becoming progressively more important. The psittacines are among the most endangered bird groups and are prime candidates for restoration through ...

Habitat Protection Alone Is Insufficient: Costa Rican Parrots Thrive in Altered Landscapes but Remain Vulnerable to Poaching

Diversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Human population growth and resource overexploitation have induced major changes in global biodiversity. Costa Rica, with 26% of its land area protected, is often cited as a model of environmental conservation. However, conservation efforts have largely focused on habitat preservation, while overharvesting remains an unquantified factor in

The first fossil parrot (Aves, Psittaciformes) from Siberia and its implications for the historical biogeography of Psittaciformes [PDF]

Biology Letters, 2016
Modern parrots (crown Psittaciformes) are a species-rich group of mostly tropical and subtropical birds with a very limited fossil record. A partial tarsometatarsus from the late Early Miocene of Siberia (Baikal Lake) is the first pre-Quaternary find of crown Psittaciformes in Asia (and Siberia in particular) and is also the northern-most find of this ...
