This study investigates why golden eagle juveniles delay emigration despite acquiring flight skills, finding that external factors, not skill mastery, primarily influence the timing of independence.

This study examines how early-life activity levels in golden eagles influence later life-history transitions, finding that higher nestling activity correlates with earlier fledging and dispersal.

This study shows golden eagles in the Alps use gravity waves for soaring, contributing to 19% of their flight segments and becoming primary updraught sources in winter.

The study shows that the realized energy landscape for golden eagles changes with age, with younger eagles having higher energy costs and smaller flyable areas.
