The counties and hotspots listed below represent well-known birding areas within the region and are provided for planning and reference. Specific trip locations vary based on season, access, and local conditions.
Humboldt County anchors northern coastal birding with its mix of lagoons, redwoods, and the vast Humboldt Bay complex. Arcata Marsh (Klopp Lake, Butcher Slough, Brackish Pond) is renowned for waterfowl and shorebirds, while Humboldt Bay NWR (Hookton Slough, Ma-le’l Dunes, Salmon Creek) blends estuaries and dunes. Humboldt Bay itself (North Spit jetty, Woodley Island, King Salmon) hosts seabirds and gulls, while the grasslands of the Arcata Bottoms (Jackson Ranch Rd., V St. Loop, Moxon Ln.) attract raptors and flocks. Prairie Creek Redwoods SP (Fern Canyon, Elk Prairie, Big Tree) adds towering forests with forest specialties. Collectively, these sites showcase Humboldt’s unmatched habitat variety and birding opportunities.
Mendocino County blends rocky shorelines, coastal headlands, and inland wetlands into a compact birding landscape. MacKerricher SP (Laguna Point, Lake Cleone, Virgin Creek) supports waterbirds and migrant shorebirds, while the Point Arena Lighthouse and Stornetta Public Lands offer seabird viewing along dramatic cliffs. The Mendocino Headlands highlight coastal trails and bluffs, while Navarro River Redwoods SP (beach, estuary, campground) provides estuarine and riparian habitats. Inland, the Ukiah WWTP & Riverside Park add accessible wetlands. Together, these sites illustrate Mendocino’s blend of coastal richness and inland variety.
Del Norte County combines rugged Pacific headlands with remote redwood groves and wetlands. Point St. George is one of the state’s best seawatch overlooks, while Crescent City Harbor (B Street Pier, Battery Point, Anchor Way) hosts gull flocks and wintering loons. Lake Earl & Tolowa (Narrows, Lakeview Dr., Buzzini Rd.) deliver expansive wetlands, while Jedediah Smith Redwoods SP (Howland Hill Rd., Stout Grove, Boy Scout Tree Trail) anchors forest birding. The Smith River (estuary, Bailey Rd., Hiouchi Visitor Center) adds riparian corridors and migration stopovers. Collectively, these sites highlight Del Norte’s dramatic combination of ocean, wetland, and ancient forest habitats

Spring (Mar–May) brings migration along coastal lagoons, estuaries, and forest edges, with warblers, flycatchers, and shorebirds on the move. Weather is cool and often damp, with frequent fog and drizzle.
Summer (Jun–Aug) highlights seabird activity offshore and breeding forest specialists in the redwoods. Days are mild, with persistent coastal fog and chilly evenings common.
Fall (Sep–Oct) brings another strong migration window, especially for shorebirds and raptors moving along the coastline. Conditions are generally dry and clear, with cool mornings and crisp afternoons.
Winter (Nov–Feb) delivers massive flocks of waterfowl to bays and wetlands, while storms push seabirds close to shore. Weather is wet and cool, with heavy rains and strong coastal winds frequent.
