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

Wildlife 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.

Prevalence and Genetic Diversity of Haemoproteus and Leucocytozoon in Raptors and Other Captive Birds at the National Zoological Garden in South Africa

Integrative Zoology, Volume 21, Issue 1, Page 203-213, January 2026.
Captive birds at the National Zoological Garden in South Africa harbor diverse haemosporidian parasite species and lineages. This might compromise conservation efforts of threatened species. ABSTRACT Avian haemosporidian infections have been associated with disease outbreaks in zoos and rehabilitation centers globally. This study aimed to determine the

Can the intake of antiparasitic secondary metabolites explain the low prevalence of hemoparasites among wild Psittaciformes?

Parasites & Vectors, 2018
Background Parasites can exert selection pressure on their hosts through effects on survival, on reproductive success, on sexually selected ornament, with important ecological and evolutionary consequences, such as changes in population viability ...

Unveiling Novel Viral Diversity, Biogeography, and Host Networks in Wildlife Through High‐Throughput Sequencing Data Mining

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Analysis of 57 536 high‐throughput sequencing datasets uncovers a vast, hidden world of viruses in wildlife. The researchers reveal significant geographic and host‐specific patterns of viruses, and their surprising cross‐species transmissions, such as avian flu viruses infecting goats.

Origin and Diversification of the Genera Aratinga, Eupsittula, and Psittacara (Aves: Psittacidae)

Diversity
The arrival of psittacine in North America is well known but undefined. It is widely accepted that these birds originated in South America, and it has been suggested that different factors have promoted the biodiversity of birds in Mexico.

Quantifying macro‐evolutionary patterns of trait mean and variance with phylogenetic location–scale models

Methods in Ecology and Evolution, Volume 16, Issue 11, Page 2585-2602, November 2025.
Abstract Understanding how both the mean (location) and variance (scale) of traits differ among species and lineages is fundamental to unveiling macroevolutionary patterns. Yet, traditional phylogenetic comparative methods primarily focus on modelling mean trait values, often overlooking variability and heteroscedasticity that can provide critical ...

Past research and future directions in understanding how birds use their sense of smell

Ibis, Volume 167, Issue 4, Page 853-881, October 2025.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...
