Functional Morphology of the Pedal Musculature and Grip Force Estimation in the Red‑and‑Green Macaw (Ara chloropterus Gray, 1859) [PDF]
Journal of Morphology, Volume 287, Issue 8, August 2026.Integration of detailed hindlimb anatomy with biomechanical analyses demonstrates that pedal performance in the red‐and‐green macaw is driven by specialized muscle architecture and force distribution. Hypertrophy of digit IV flexor musculature, together with modifications of the intrinsic and extensor muscles, enhances grasping stability, climbing, and

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia [PDF]
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Variation in parrot jaw musculature [PDF]
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,

Morphological description and molecular characterization of Leucocytozoon australis sp. nov. (Apicomplexa: Haemosporida: Leucocytozoidae) infecting the Austral parakeet (Enicognathus ferrugineus), an endemic parrot from the southern Andes [PDF]
International Journal for Parasitology: Parasites and WildlifeBirds of the order Psittaciformes are rarely infected by haemosporidian blood parasites in the wild, and the few records of Leucocytozoon in parrots correspond to host-generalist lineages detected in captive birds.

Species Determination Within the Felidae Family Using mtDNA Minibarcoding [PDF]
Animal Genetics, Volume 57, Issue 4, August 2026.ABSTRACT Wildlife forensic analysis frequently deals with highly degraded DNA samples, including those from tanned hides, processed products of traditional Chinese medicine, and specimens stored in preservation fluids. These samples present significant challenges for traditional DNA barcoding due to the difficulty of amplifying sufficiently long DNA ...

First Documentation of Exophiala spp. Isolation in Psittaciformes
Animals, 2022 Several fungi species are reported to act as opportunistic agents of infection in avian species. After the isolation of Exophiala spp., a dematiaceous fungal pathogen associated with a mucosal lesion in a military macaw (Ara militar), samples were ...

From the cage to the wild: introductions of Psittaciformes to Puerto Rico [PDF]
PeerJ, 2018 Introduced psittacine birds can become highly invasive. In this study, we assessed invasions of Psittaciformes in Puerto Rico. We reviewed the literature, public databases, citizen science records, and performed in situ population surveys across the ...

Comparative mitogenomic analyses of Amazona parrots and Psittaciformes [PDF]
Genetics and Molecular Biology, 2018 Amazon parrots are long-lived birds with highly developed cognitive skills, including vocal learning. Several parrot mitogenomes have been sequenced, but important aspects of their organization and evolution are not fully understood or have limited ...
