Blue grouse are commonly spotted in mountain meadows.

A peregrine falcon swoops down on a shorebird running along the beach. A long, cheerful, warble reveals a tiny winter wren singing hidden among the forest understory. Deep, hooting calls of a blue grouse resonate across a mountain meadow. These are just a few of the many birds -- about 300 species in all -- that add color and song to the diverse habitats found in Olympic National Park.
