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.

Primeiro registro de depredação do náutilo Argonauta nouryi (Cephalopoda: Argonautidae) pelo gavião-caranguejeiro-negro Buteogallus anthracinus (Accipitriformes: Accipitridae)

, 2017
La depredación de cefalópodos por parte de aves no marinas es rara, sobre todo en aves del orden Accipitriformes. Las observaciones se llevaron a cabo in situ y la identificación de Argonauta nouryi fue completamente basada en la forma de la concha.

Hard tick infestation of birds of prey (Aves: Accipitriformes, Strigiformes, Falconiformes) in the Western Palearctic: New data and literature review

Ticks and Tick-Borne Diseases
Tick infestation of songbirds has been extensively studied at global and regional scales but relevant data on birds of prey remain scarce and fragmentary.

A reference genome for the Harpy Eagle reveals steady demographic decline and chromosomal rearrangements in the origin of Accipitriformes. [PDF]

Sci Rep
The Harpy Eagle (Harpia harpyja) is an iconic species that inhabits forested landscapes in Neotropical regions, with decreasing population trends mainly due to habitat loss, and currently classified as vulnerable.

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

Ecology 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.

Taxonomic status of Cyathostoma nematodes (Nematoda: Syngaminae) parasitizing respiratory tracts of birds of prey and owls in Europe and North America: how many species are there?

Helminthologia, 2016
So far, the identity of Cyathostoma (Hovorkonema) nematodes collected from respiratory tracts of birds of prey (Accipitriformes, Falconiformes) and owls (Strigiformes) in Europe and North America is extremely inconsistent.

Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing

Zoo Biology, Volume 45, Issue 2, Page 97-108, March/April 2026.
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.
