Functional Morphology of the Pedal Musculature and Grip Force Estimation in the Red‑and‑Green Macaw (Ara chloropterus Gray, 1859)

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

DNA barcoding for identification of species involved in wildlife strikes at Brazilian airports

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
A collaborative network of 42 Brazilian airports applied DNA barcoding to identify 80 species involved in wildlife strikes. Among them, 32 species (17 birds and 15 bats) were not currently available in Brazil's wildlife strike reporting database, underscoring the value of molecular tools for strengthening wildlife strike monitoring. Abstract This study

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 305-322, June 2026.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Trophic Niche Breadth of Falconidae Species Predicts Biomic Specialisation but Not Range Size

Biology, 2022
Trophic niche breadth plays a key role in biogeographic distribution patterns. Theory posits that generalist strategies are favoured in a more heterogeneous set of environments across a spatio-temporal gradient of resources predictability, conferring ...

An overview of the oldest and most comprehensive avifauna of the early Eocene British London Clay

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Early Eocene birds from the British London Clay have been known for two centuries, but a comprehensive understanding of the avifauna of the London Clay Formation is still in its infancy. In the present study, the bird assemblage of the Walton Member is reviewed, which represents one of the oldest subdivisions of the formation.

A Global, Taxon‐Stratified, High‐Resolution Sampling‐Effort Dataset From GBIF for Bias‐Aware Ecological Modelling

Diversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Introduction and Aim Spatiotemporal and taxonomic sampling bias in biodiversity occurrence data poses critical challenges for robust ecological inference, species distribution models (SDMs), and conservation planning. Despite the exponential growth in global biodiversity records over recent decades, these biases persist.
