Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

Animal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

Challenges in population monitoring: Bar‐tailed Godwits (Limosa lapponica) on the East Atlantic Flyway defy assumed population structure

Ibis, EarlyView.
Estimating and monitoring migratory bird populations involves significant challenges, even in the most well‐studied and easily‐counted species, and can be further complicated by long‐held but unverified assumptions and by shifting distributions in changing flyway conditions.

Functional constraints on the number and shape of flight feathers

Proceedings of the National Academy of Sciences
As a fundamental ecological aspect of most organisms, locomotor function significantly constrains morphology. At the same time, the evolution of novel locomotor abilities has produced dramatic morphological transformations, initiating some of the most significant diversifications in life history. Despite significant new fossil evidence, it

Field‐based evidence of impaired sperm quality associated with conventional farming in two passerine birds

Ibis, EarlyView.
The detrimental effects of conventional farming on bird biodiversity are increasingly documented. Despite this, the specific impacts of both organic and conventional farming practices on bird coloration and sperm quality in natural settings remain unexplored. This study aimed to determine whether these farming practices differentially affect body mass,
