The black skimmer is a unique bird found along coastal regions in North America, particularly in areas like Florida and California. It is easily recognizable by its striking black upper body, white underbelly, and long, slender wings. The most distinctive feature is its elongated bill, which has a lower mandible that is longer than the upper one, allowing it to skim the water's surface while feeding on small fish. These birds typically nest in colonies on sandy beaches or islands, laying their eggs in shallow scrapes in the sand. They are social creatures, often seen flying in groups and communicating with a series of calls. The black skimmer is an important part of the coastal ecosystem, helping to control fish populations and serving as an indicator of environmental health.
