Tiny songbird crosses Sahara by flying night after night

Phys · Apr 23, 2026 · 453 words · By Johan Joelsson

New research from Lund University details the migration strategy of the thrush nightingale, a small songbird that crosses vast deserts like the Sahara. The study reveals that these birds minimize energy use by flying continuously at night and remaining inactive during the day. The research was conducted using advanced sensors and highlights the species' ability to survive long journeys on stored energy reserves.
