Projected impacts of climate change on habitat availability for an endangered parakeet.

PLoS ONE, 2018
In tropical montane cloud forests, climate change can cause upslope shifts in the distribution ranges of species, leading to reductions in distributional range. Endemic species with small ranges are particularly vulnerable to such decreases in range size,

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, Volume 248, Issue 5, Page 873-887, May 2026.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Exploitation of Erythrina dominguezii Hassl. (Fabaceae)nectar by perching birds in a dry forest in western Brazil

Brazilian Journal of Biology, 2002
Among the vertebrate pollinated plants, the genus Erythrina includes tree species in which birds are the pollen vectors. Two groups in this genus may be distinguished: a) the hummingbird, and b) the perching bird pollinated species. Erythrina dominguezii

Chlamydophila psittaci Transmission from Pet Birds to Humans

Emerging Infectious Diseases, 2007
We studied zoonotic transmission of Chlamydophila psittaci in 39 breeding facilities for Psittaciformes (cockatoos, parrots, parakeets, lories) that frequently used antimicrobial drugs.

Hybridization and Immunology in Animals: A Review

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Hybridization can reshape immune function by introducing novel genetic variation and combining parental immune traits. Across animal taxa, this process may influence resistance, tolerance, and pathogen dynamics, with important implications for disease ecology and One Health.

Interactions between Invasive Monk Parakeets (Myiopsitta monachus) and Other Bird Species during Nesting Seasons in Santiago, Chile

Animals, 2019
The monk parakeet (Myiopsitta monachus) is considered to be one of the most invasive bird species because its unique ability among parrots to build their own communal nests.

The Influence of Intrinsic Factors and Release Trials on Site Fidelity and Dispersal of Reintroduced Golden Parakeets (Guaruba guarouba, Aves, Psittacidae)

Diversity
Reintroducing threatened fauna has been established as a valuable conservation practice despite the obstacles that such projects still face. In avian reintroductions, elevated dispersal of released individuals is one of the main factors preventing the ...

Attitudes to Exotic Parakeets: A Comparative Case Study and Citizen Science Review

Diversity
Invasive, non-native species are recognised as a global problem, and their dispersal and introduction are controversial topics. However, a source of particular interest is that of human–nature interactions and consequent perceptions of natives and non ...

Flowers, fruits, and the abundance of the yellow-chevroned parakeet (Brotogeris chiriri) at a gallery forest in the South Pantanal (Brazil) Flores, frutos e abundância do periquito-de-asa-amarela (Brotogeris chiriri) em uma mata ciliar do Pantanal Sul (Brasil)

Brazilian Journal of Biology, 2004
Parakeets usually forage for massive and ephemeral plant resources at forest canopies. Fruit pulp is widely cited as a major food resource for these birds, which often eat seeds and nectar.
