Definition
A 'skimmer' is a bird belonging to the genus 'Rynchops,' known for its unique feeding behavior. It flies low over the water with its lower mandible skimming the surface, catching small fish. There are three species of skimmers found in tropical and subtropical regions. Their most notable feature is their elongated lower mandible. Think of them as a water-based version of a street sweeper, collecting food as they go. This specialized adaptation makes them efficient predators.
