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.
Other Habitats Our Birds Need
Coastal Dunes and Beaches
Coastal dunes and beach communities face a dynamic, harsh environment that requires plants to have unique survival mechanisms.
Conifer Forest
Conifer forests, including our magnificent temperate rainforests, dominate the Pacific Northwest from California to southeast Alaska.
Estuaries
Estuaries occur where freshwater rivers meet the salt waters of the ocean. They are one of most biologically rich habitats on Earth, thanks to the mixing of nutrients from both the land and sea.
Freshwater Wetlands
Freshwater wetlands are the hallmark of the Pacific Americas Flyway. Wetlands are subject to periodic flooding and are further characterized by their soil type, hydrology and vegetation.
Hawaiian Wetlands
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. They may be rocky cliffs, boulder rubble, wave-pounded shelves, or sheltered rocky shores.
Oak and Prairie
Oak and prairie ecosystems support a unique suite of specialized birds. They are home to a handful of imperiled species such as Streaked Horned Lark and Oregon Vesper Sparrow.
Pacific Atolls
An atoll is a coral reef island, or islets. They are are characteristically ring-shaped with a central lagoon, and sometimes a central island.
Pelagic
Pelagic habitats, one of many habitats in the marine environment, include the open ocean. Birds that spend time in the pelagic zone must be able to withstand the salt water, wind and waves–and some do for years at a time.
