Molecular changes and physiological responses involved in migratory bird fuel management and stopover decisions.

ABSTRACT: Migratory birds undertake long journeys across continents to reach breeding habitats with abundant resources. These migrations are essential for their survival and are shaped by a complex interplay of physiological adaptations, behavioral cues, and gene expression patterns. Central to migration are stopovers, critical resting points where birds replenish energy stores before continuing their journey. In this study, we integrate physiological measurements, behavioral observations, and molecular data from temporarily caged migrating Garden Warblers (Sylvia borin) to gain insights into their stopover strategies and physiological adaptations after crossing the extended ecological barrier formed by the Sahara Desert and the Mediterranean Sea. Depleted individuals, marked by low body mass and fl
