Study | Migratory nightjars roost on asphalt to reduce thermoregulatory costs and increase fuel accumulation

An 8-year study of red-necked nightjars found that birds preferentially roosted on thermally favorable asphalt roads during moonlit nights, potentially reducing thermoregulatory costs. This behavioral thermoregulation may improve energy balance and facilitate faster fuel deposition before migration.
