A survey of the uncinate bone and other poorly known ossicles associated with the lacrimal/ectethmoid complex of the avian skull

open access: yesThe Anatomical Record, Volume 305, Issue 9, Page 2312-2330, September 2022., 2022
Abstract In several taxa of Neornithes (crown group birds), the lacrimal/ectethmoid complex exhibits small bones, the comparative osteology of which is poorly studied. Some of these ossicles—which are commonly known as uncinate bones (ossa uncinata or ossa lacrimopalatina)—were already described two centuries ago, but knowledge of their distribution ...

Co‐infections: Simultaneous detections of West Nile virus and Usutu virus in birds from Germany

open access: yesTransboundary and Emerging Diseases, Volume 69, Issue 2, Page 776-792, March 2022., 2022
Abstract The emergence of West Nile virus (WNV) and Usutu virus (USUV) in Europe resulted in significant outbreaks leading to avifauna mortality and human infections. Both viruses have overlapping geographical, host and vector ranges, and are often co‐circulating in Europe.

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

open access: yesJournal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Surgical management of an open humeral fracture in a greater rhea (Rhea americana): Internal placement of a locking compression plate and post‐operative complications

open access: yesVeterinary Record Case Reports, Volume 14, Issue 2, May 2026.
SUMMARY A 17‐year‐old, 24‐kg, female greater rhea (Rhea americana) presented with an acute onset of left wing droop. Clinical examination and radiographs revealed an open, simple, displaced, short‐oblique diaphyseal fracture of the distal third of the left humerus.

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

open access: yesDiversity 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.

Testing Mini-FLOTAC for the Monitorization of Gastrointestinal Parasitic Infections in Birds Kept at Four Iberian Zoological Institutions

open access: yesJournal of Zoological and Botanical Gardens
Birds kept in zoological institutions are highly exposed to gastrointestinal (GI) parasitism caused by coccidia and nematodes. The current research aimed to characterize the avian GI parasitic fauna in several zoological collections in Portugal and Spain.

Unruffling the global feather trade: a comparative analysis of CITES and LEMIS records of feathers and bird skins

open access: yesWildlife Biology, Volume 2026, Issue 1, January 2026.
During the 18th and 19th centuries, bird feathers (class: Aves) were harvested from wild populations and sold globally in enormous quantities to meet the rising demand of the fashion industry. Although many laws now prevent similar widescale harvest, there is a paucity of studies on the trade that has continued to occur since the 20th century.

Bone Mineral Density of Willow Ptarmigan (Lagopus lagopus) as a Potential Taphonomic Factor in Skeletal Part Attrition

open access: yesInternational Journal of Osteoarchaeology, Volume 35, Issue 5, Page 284-294, September/October 2025.
ABSTRACT Agents of taphonomy can bias skeletal parts and the frequency of bones in archaeological sites. An important factor to consider is the possible effect of bone density‐mediated attrition on archaeornithological assemblages. We scanned willow ptarmigan (Lagopus lagopus) specimens using a Lunar iDXA and an enCcore small animal body add‐on to ...

The Lithornithiformes (Aves) from the early Eocene London Clay of Walton‐on‐the‐Naze (Essex, UK)

open access: yesPapers in Palaeontology, Volume 11, Issue 1, January/February 2025.
Abstract We describe multiple partial skeletons and isolated bones of the palaeognathous Lithornithiformes from the early Eocene London Clay of Walton‐on‐the‐Naze (Essex, UK). The well‐preserved specimens are assigned to at least four species of the taxa Lithornis and Pseudocrypturus. Two species of Lithornis are identified as L. nasi and L.
