Habitat - Seacoasts are regions where the land meets the sea. The land itself may be sandy, muddy, gravelly, or rocky. Cliffs may be present. Some regions may be exposed to pounding surf while others may be protected by the calm waters of inlets, bays, and harbors. Both areas, however, are alternately exposed and submerged by the tides.
When the tide is full the seashore is a water world and at ebb tide it provides a rich feeding area for many land birds. Many colonial nesting birds, like gulls and kittiwakes, raise their young on precipitous cliffs while other species, like the Black Oystercatcher, breed along the upper beaches. Large predators, like eagles and ospreys, build their stick nests in large trees bordering the sea edge.
The songs and calls of many birds inhabiting seacoasts can be heard throughout the year.
