Comparative brain morphology of Neotropical parrots (Aves, Psittaciformes) inferred from virtual 3D endocasts [PDF]

open access: yes, 2021
Psittaciformes are a very diverse group of non-passerine birds, with advanced cognitive abilities and highly developed locomotor and feeding behaviours.

Origin and Diversification of the Genera Aratinga, Eupsittula, and Psittacara (Aves: Psittacidae)

open access: yesDiversity
The arrival of psittacine in North America is well known but undefined. It is widely accepted that these birds originated in South America, and it has been suggested that different factors have promoted the biodiversity of birds in Mexico.

Hindlimb myology of the monk parakeet (Aves, Psittaciformes)

open access: yesJournal 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.

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 830-842, May 2026.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Alignment visualization for the 2015./2014.Psittaciformes alignment, with coverage globally applied.

open access: yes, 2019
This alignment corresponds to the Fig 1 input, and shows reasoner-inferred non-/congruent concepts and articulations (see legend)–i.e., none in this particular case.

Beyond Species Diversity: Functional Approaches Reveal Consistent Fauna Community Responses to Exotic Grass Invasion in Arid Lands

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
To assess whether the impacts of exotic plant invasion can be generalised across taxa, we developed a conceptual framework predicting faunal responses to grass invasion in open, arid ecosystems and tested our predictions using data on birds, reptiles and ants from sites invaded by buffel grass (Cenchrus ciliaris) and paired uninvaded sites.

Harnessing iEcology data to uncover invasive species behaviour

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 4, Page 1022-1031, April 2026.
Abstract Invasive animal species threaten ecosystems, biodiversity and human livelihoods. Behavioural traits such as boldness, exploratory tendencies, learning ability and social interactions are known to influence invasion success. Yet these behavioural traits remain underexplored due to challenges in observing behaviour across large spatial and ...

Lost companions: a new quill mite species and its possible coextinction with the Carolina parakeet

open access: yesParasitology
Investigations of the parasites associated with extinct avian species provide unique insights into the ecology and evolution of both hosts and their parasitic counterparts. In the present paper, a new quill mite species, Peristerophila conuropsis sp. n.,

Airborne Environmental DNA Analysis as a Tool to Monitor Live Bird Trade

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
We explore airborne environmental DNA (eDNA) analysis as a novel tool to detect avian species and assess its potential for monitoring bird trade. We collected airborne samples in both enclosed and open market environments, accompanied by visual surveys, and processed them using DNA extraction and metabarcoding to identify avian taxa.

Additional file 1: of Can the intake of antiparasitic secondary metabolites explain the low prevalence of hemoparasites among wild Psittaciformes?

open access: yes, 2018
Table S1. Hemoparasites in wild Psittaciformes. Malaria parasites (Plasmodium), related intracellular haemosporidians (Haemoproteus and Leucocytozoon), the unicellular parasitic flagellate protozoans (Trypanosoma), and microfilaria reported in wild ...
