This study reveals that sunbirds use intralingual suction to drink nectar, a unique mechanism not found in other animals.

The paper investigates how introgression through narrow contact zones affects gene-tree heterogeneity in an African bird clade, finding introgression shapes phylogenetic signals even in allopatric populations.

This study examines the metabolic responses of common waxbills to cold temperatures in their native range, identifying a metabolic inflection point at 16°C that may indicate an adaptive energy-saving strategy.
