Riparian corridors occur along rivers and streams and across floodplains and terraces. Healthy riparian systems have a dense plant cover that provides shade, predator protection, food, and nesting habitat for resident and migratory birds. In many Pacific Birds areas, the riparian zones that birds depend upon has been diminished by the removal of native vegetation and the introduction of invasive species. Riparian areas are especially important to landbirds, notably Neotropical migrants.
Riparian habitats are ecological transition zones that connect fast moving water, stagnant wetlands and shaded uplands. These habitat niches result in high bird diversity and abundance. Waterfowl might be found in the slower moving habitats, while American Dipper and Belted Kingfisher frequent the shoreline. Willow Flycatchers and Yellow Warblers inhabit the under and mid-story vegetation, while Bank Swallows nest along the bluffs.
Habitats Our Birds Need
Arctic and Subarctic Tundra
Alaska has vast expanses of arctic and subalpine tundra characterized by low temperatures, permafrost, and a short growing season.
Coastal Dunes and Beaches
Coastal dunes and beach communities face a dynamic, harsh environment that requires plants to have unique survival mechanisms.
Conifer forests, including our magnificent temperate rainforests, dominate the Pacific Northwest from California to southeast Alaska.
Hawaiian Montane Forest
‘Ohi’a and in some areas koa trees dominate the canopy of the lush cloud forests found on the higher elevations of Kaua’i, Maui, Hawai’i, O’ahu, and Moloka’i.
Hawaii’s freshwater wetlands support the Ae’o, or Hawaiian Stilt, and five other species of endemic, endangered waterbirds.
Intertidal Rocky Shorelines
Rocky shorelines along the North Pacific coastline occupy the region between high and low tide.
An atoll is a coral reef island, or islets. They are are characteristically ring-shaped with a central lagoon, and sometimes a central island.
