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.

*Study | Mechanisms matching timing to resources: comparisons of closely related seasonally sympatric, migratory and non-migratory populations

The climate is warming, and many bird species are keeping up by altering when they migrate, breed, and molt, that is, by altering their phenology. To make accurate predictions about future responses to climate warming, knowledge of the mechanisms regulating timing is needed.
