The question of whether these coastal birds ingest saline liquid is a common one. While it might seem counterintuitive, the physiological adaptations of these animals allow them to thrive in environments where freshwater is scarce. The process involves specialized glands that effectively remove excess sodium chloride from their systems.
The ability to process and excrete high concentrations of salt is vital for survival in marine and coastal ecosystems. This adaptation reduces reliance on freshwater sources, minimizing competition with other species. Historically, this physiological trait has allowed these birds to colonize various saline habitats worldwide, contributing to their ecological success.
