The first fossil parrot (Aves, Psittaciformes) from Siberia and its implications for the historical biogeography of Psittaciformes [PDF]

open access: yesBiology Letters, 2016
Modern parrots (crown Psittaciformes) are a species-rich group of mostly tropical and subtropical birds with a very limited fossil record. A partial tarsometatarsus from the late Early Miocene of Siberia (Baikal Lake) is the first pre-Quaternary find of crown Psittaciformes in Asia (and Siberia in particular) and is also the northern-most find of this ...

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

open access: yesPapers 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.

Integumentary fibrosarcoma in a free‐living swan (Cygnus olor): Medical and welfare considerations

open access: yesVeterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract A 10‐kg adult male mute swan (Cygnus olor) of unknown age was admitted for investigations of two large ventral masses overlying the keel bone, which were discharging purulent material. The masses measured 8.9 × 2.1 cm and 4.2 × 3.2 cm. Empirical treatment with non‐steroidal anti‐inflammatory drugs and antimicrobials was instigated.

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.
