Beak Morphological Adaptation in Ethiopian Finches (Fringillidae) Across Environmental Gradients: An Ecological and Evolutionary Synthesis

2026-01-23

Abstract excerpt

Ethiopian finches (Fringillidae) provide a continental-scale system for examining how environmental gradients shape functional trait evolution. This review synthesizes current knowledge on the evolution of beak traits in Ethiopian finches across the country’s highlands, integrating evidence from diet composition, habitat heterogeneity, thermoregulatory demands, and human-mediated environmental change. Beak diversi...
