eBird Northwest Habitat Pages

Estuaries occur where freshwater systems connect and intermingle with the salt waters of the ocean. Estuaries are actually an ecosystem made up of numerous habitats, such as tidal mud flats, eelgrass beds¬ or saltwater marshes.
The marine environment of the Pacific Northwest is diverse, ranging from shallow estuarine conditions to deep, blue, offshore waters. Pacific Northwest waters are contained in both the California Current Large Marine Ecosystem and the Salish Sea.
Riparian (river and streamside) vegetation provides habitat for many species of breeding, migrating, and overwintering birds. In the western United States, riparian zones make up <1% of the land area, yet they support the most diverse bird communities in the Pacific Northwest.
Grassland habitats are found throughout much of North America. They vary widely in structure, characteristics, and diversity but are typically defined as land dominated by grasses and/or forbs.
In a landscape dominated by conifers, oak ecosystems of the Pacific Northwest are unique and support a rich array of plants and animals. They are often associated with dry, low-elevation sites and sites that experienced regular fires in the past.
Sagebrush-dominated lands cover much of western North America, including portions of eastern Oregon and Washington. The structure and characteristics of sagebrush communities vary widely, but vegetation is typically a mix of grasses, forbs, and shrubs adapted to dry conditions.
