Volatile Compounds in Feathers of the Scarlet Macaw (Ara macao) Reflect Sex and Pair‐Bond Status
Integrative Zoology, EarlyView.Scarlet macaws exhibit sex‐ and pair‐related differences in plumage volatile composition, with males showing greater chemical richness. Partnered individuals differ in specific compound classes, whereas no clear association with immune function was detected. These results support a potential role for olfactory cues in sexual and social communication in

Trade and the conservation status of the family Psittacidae in Venezuela [PDF]
Bird Conservation International, 1991 SummaryAn assessment of trade in parrots throughout Venezuela, 1988–1989, reveals alarmingly high internal and international levels. The national trade has main outlets in major cities, but is now compounded by the use of feathers for Indian artifacts sold to tourists.

Conservation Science and Practice, Volume 8, Issue 10, October 2026.This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory
Oikos, Volume 2026, Issue 9, September 2026.Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

The Effects of Land‐Use Dynamics on Avian Phylogenetic Diversity Across Island Ecosystems
Journal of Biogeography, Volume 53, Issue 7, July 2026.ABSTRACT Aim To test whether forest extent and recent forest‐cover change are associated with avian phylogenetic diversity and community‐level evolutionary value across islands. Location Seven islands spanning Borneo and Wallacea in the Malay Archipelago. Taxon Terrestrial birds. Methods We sampled 1410 sites (2010–2022).
