Few regions in North America offer the sheer diversity of the Pacific Northwest. Within a single day, a birder can move from coastal tidepools teeming with alcids to old-growth rainforests resonant with Spotted Owls, over the Cascades to sagebrush flats alive with Sage Thrashers, and back again. Washington, Oregon, and British Columbia together host over 500 regularly occurring species — a staggering variety driven by the collision of oceanic, montane, and interior climates.
📍 Coverage: This guide focuses on 8 regions across Washington, Oregon, and coastal British Columbia. Each region chapter includes an introduction, seasonal best-times, signature species, and curated hotspot cards for the most productive sites.

Seabirds
World-class pelagic birding off both coasts. Pink-footed Shearwaters, Laysan Albatrosses, and storm-petrels by the thousands.
Shorebirds
Grays Harbor hosts millions of shorebirds in April–May. The largest concentration in the Western Hemisphere outside Alaska.
Forest Specialties
Spotted Owl, Marbled Murrelet, Vaux's Swift, and the full suite of "Olympic specialties" are near-obligatory target species.
Raptors
The Columbia River Gorge is one of N. America's finest raptor-watching areas. Ferruginous Hawks, rough-legs, and falcons in winter.
Waterfowl
Klamath Basin hosts the largest concentration of wintering Bald Eagles in the lower 48 and spectacular waterfowl migrations.
Endemics
Several near-endemic species and subspecies including Streaked Horned Lark, Oregon Vesper Sparrow, and Sooty Grouse.
Best seasons vary dramatically by region. Use this table to plan multi-stop itineraries that hit peak windows across regions.
| Region | Jan–Feb | Mar–Apr | May–Jun | Jul–Aug | Sep–Oct | Nov–Dec |
|---|---|---|---|---|---|---|
| Olympic Peninsula | Owls | Migrants | Breeding | Seabirds | Shorebirds | Winter |
| Puget Sound / San Juans | Wintering sea ducks | Migrants | Breeding | Quiet | Fall migrants | Sea ducks |
| North Cascades | Snow; limited | Still snow | Breeding begins | Peak birds | Fall migration | Closed roads |
| E. WA Shrubsteppe | Cold; few birds | Leks active | Breeding / Songbirds | Summer | Fall migrants | Quiet |
| Columbia Gorge | Raptors | Raptors peak | Breeding | Summer | Hawk watch | Waterfowl |
| Willamette Valley | Wintering Sandhill Cranes | Dusky Canada Geese | Breeding | Quiet | Fall | Waterfowl |
| Oregon Coast | Storm petrels; seabirds | Shorebirds begin | Shorebirds, breeding | Pelagic peak | Fall waders | Seabirds |
| Klamath Basin | Bald Eagles, Waterfowl | Migration begins | Breeding | Quiet | Waterfowl peak | Eagles, cranes |
May offers breeding birds in song in the mountains, peak shorebird migration at Grays Harbor, and full access to high-elevation Cascade sites. If you only have one week, make it the last week of May.
January in the PNW rewards the hardy birder. Klamath Basin's eagle spectacle, Puget Sound sea ducks, and irruptive finches across the region make it an underrated time to visit.
Washington · Old-growth rainforest, Pacific coast, alpine
The Olympic Peninsula is a world-class destination — a UNESCO Biosphere Reserve protecting one of the last temperate rainforests on earth. The Hoh Rainforest receives 140 inches of rain annually, sustaining towering Sitka Spruce festooned with club mosses and an extraordinary community of moisture-loving birds. The Peninsula's isolation has also produced endemic subspecies found nowhere else.
Best strategy: Arrive at the Hoh Rainforest before dawn in May–June. Listen for Spotted Owls along the Hall of Mosses trail at dusk. For Marbled Murrelets, stake out large clearings near old-growth at first light — their fast-flying silhouettes are unmistakable.
Premier old-growth site. Spotted Owl reliable along upper Hoh Trail in spring. Varied Thrush song abundant. Winter Wrens everywhere. Olympic Chipmunks and Roosevelt Elk on trails.
Outstanding rocky coastline for seabirds. Black Oystercatcher, Pigeon Guillemot, Rhinoceros Auklet, Common Murre, and Tufted Puffin visible year-round off the sea stacks.
Alpine meadows in July–August host Horned Lark, American Pipit, and Gray-crowned Rosy-Finch. Blue Grouse on ridge roads at dawn. Stellar views of the Olympic Range.
Species details · Best timing · Gear tips
| Month | Key Activity | Target Species |
|---|---|---|
| Jan–Feb | Owls / winter finches | Varied Thrush, Sooty Grouse |
| Mar–Apr | Early migrants | Rufous Hummingbird, swallows |
| May–Jun | Peak breeding | Spotted Owl, Marbled Murrelet |
| Jul–Aug | Seabirds peak | Tufted Puffin, Black Oystercatcher |
| Sep–Oct | Fall migration | Shorebirds at La Push beach |
| Nov–Dec | Winter birds | Varied Thrush, Steller's Jay |
Gear note: Waterproof footwear is essential year-round. The Hoh receives rain nearly 300 days per year. Bring a scope for seabird viewing at Rialto Beach and La Push sea stacks.
One of the Western Hemisphere's great shorebird spectacles in late April. Up to 1 million Western and Dunlin sandpipers. Often visible from the levee trail without optics.
Departure point for excellent pelagic trips (WCAS runs trips August–October). Rocky jetty hosts Black Turnstone, Surfbird, Wandering Tattler, and large tern flocks in fall.
The "Banana Belt" of the Olympic Peninsula — surprisingly dry and sunny. Long sandspit yields excellent shorebirds and waterfowl. Brant in spring; Dunlin in winter.
Washington · Marine waters, islands, estuaries
Puget Sound's protected marine waters host extraordinary concentrations of wintering sea ducks, loons, and grebes. The San Juan Islands add a unique archipelago component — ferry rides yield alcids, marine mammals, and Bald Eagles perched on every bluff. Padilla Bay and the Skagit Flats are some of the finest waterfowl habitat in the Pacific flyway.
Ferry strategy: The Washington State Ferry from Anacortes to the San Juans is one of the continent's best seabirding "pelagic" trips accessible without a boat charter. Buy a round-trip pass and scan continuously — October–March is peak for alcids and loons.
One of Washington's most important estuaries. Thousands of Brant in spring; Dunlin in enormous flocks Nov–Mar; Snowy Owls in irruption years along the dike trail.
Reliable winter sea duck site. Harlequin Duck year-round on rocks. Barrow's and Common Goldeneye, mergansers, and occasional scoters in the narrows current.
Lighthouse area with outstanding sea watching. Rhinoceros Auklets, Pigeon Guillemots, Marbled Murrelets, and occasional Tufted Puffins. Peregrine Falcons hunt here daily.
Additional sites · Seasonal timing · Skagit Valley extension
The Skagit Flats north of Mount Vernon are among the most spectacular birding sites in the Pacific Northwest during winter. The tulip-field farmland and flooded fields host massive flocks of Snow Geese, Trumpeter Swans, Dunlin, and raptors including Snowy Owl in irruption years, Rough-legged Hawk, Peregrine, and the local Puget Sound race of White-tailed Kite.
| Month | Key Activity | Species |
|---|---|---|
| Oct–Nov | Migration | Dunlin murmurations, sea ducks arrive |
| Dec–Feb | Winter peak | Snow Geese, Trumpeters, Snowy Owls |
| Mar–Apr | Spring | Brant migration; Shorebirds begin |
| May–Jul | Breeding | Pigeon Guillemot, Rhinoceros Auklet |
January through February is the peak for Trumpeter and Tundra Swans. Snow Goose flocks of 20,000–40,000 are regular. Check flooded fields near Fir Island Road at sunrise.
Fast-flowing saltwater channel produces reliable Harlequin Duck viewing year-round. Rhinoceros Auklet, Pigeon Guillemot, and Peregrine Falcon regularly seen off the bridge.
Excellent seabird watching from the ferry terminal and American Camp. Orca whales frequently visible from shoreline. Pelagic Cormorant colonies on nearby cliffs.
Washington · Alpine, old-growth, mountain lakes
The North Cascades are one of the most spectacular — and underbirded — regions in the Pacific Northwest. The rugged peaks and deep valleys of North Cascades National Park and the surrounding wilderness host a suite of montane species that require real effort to find: Black-backed Woodpecker in recent burn areas, American Three-toed Woodpecker, Gray-crowned Rosy-Finch above treeline, and White-tailed Ptarmigan on talus slopes above 7,000 feet.
Access note: North Cascades Highway (SR 20) is closed approximately November–April due to snowpack. Peak birding is July–August when high-elevation roads are open and alpine species are most accessible.
On a good July morning, White-tailed Ptarmigan, Gray-crowned Rosy-Finch, and Horned Lark can all be seen at Artist Point. American Pipit and Black Swift overhead. Spectacular mountain scenery.
Rocky alpine areas accessible from SR 20 pulloffs. Clark's Nutcracker, Gray Jay, and Stellar's Jay along the roadside. Mountain Goats visible on nearby screes. Pygmy Owl in subalpine fir.
Transition zone between Cascades and shrubsteppe. Mountain Bluebird in open country; Lewis's Woodpecker in burned areas; Long-eared Owl in winter riparian sections. Excellent for raptors.
Seasonal guide · Birding routes · Logistics
The SR-20 corridor from Burlington to Winthrop makes one of the finest birding day-drives in Washington. Allow 2 days for a proper loop — west side in the morning (alpine birds), east side (shrubsteppe specialties) in afternoon.
Stop 1 — Marblemount (riparian)
Harlequin Duck on the Skagit River. Common Merganser. American Dipper on rocky cascades. Osprey nesting in summer.
Stop 2 — Rainy Pass (alpine)
Park at the Rainy Lake trailhead. Walk the paved trail for Clark's Nutcracker, Golden Eagle, and Black Swift in the cliff faces above.
Stop 3 — Washington Pass Overlook
White-tailed Ptarmigan possible on rocky slopes. White-crowned and Fox Sparrow in shrubs. American Pipit in open rocky areas above the overlook.
Stop 4 — Methow Valley / Winthrop
Mountain Bluebird along fence lines. Calliope and Black-chinned Hummingbirds at feeders. Loggerhead Shrike in open shrubsteppe east of town.
| Period | Access | Best Birds |
|---|---|---|
| Jan–Apr | Low elevations only | Wintering finches, Bohemian Waxwing |
| May–Jun | SR-20 opens | Breeding songbirds, Calliope Hummingbird |
| Jul–Aug | Full access | All alpine species, shorebirds on snowmelt |
| Sep–Oct | Good until snow | Rosy-Finch flocks, fall migration |
| Nov–Dec | Road closes | Valley owls, winter finches |
Black-backed Woodpecker strategy: Check burn areas from wildfires 2–5 years old in the Okanogan National Forest. Contact the Methow Valley ranger district for the most recent post-fire woodpecker reports.
Washington · Sagebrush, channeled scablands, wheat country
Cross the Cascades and you enter a completely different world — and a completely different bird community. Eastern Washington's sagebrush steppe holds species found nowhere in western Washington: Sage Thrasher, Brewer's Sparrow, Sage Sparrow, Common Poorwill, and the charismatic Greater Sage-Grouse at their booming lek sites in March.
Lek watching: Greater Sage-Grouse leks are active from mid-February through April, peaking in March. Arrive 45 minutes before dawn and watch from your car (vehicles are the best blind). Contact WDFW for permitted lek viewing locations in Lincoln, Grant, and Douglas Counties.
Outstanding mix of sagebrush and rocky lakeshore. Burrowing Owls nest in rock piles. Short-eared Owls hunt at dusk over fields. Waterfowl on the lakes; American White Pelican in summer.
One of WA's best sagebrush sites. Sage and Brewer's Sparrows, Sage Thrasher, and Common Poorwill at dusk in May. Long-billed Curlew in open grasslands adjacent to preserve.
Famous Memorial Day Weekend campout draws 200+ birders. Ponderosa pine habitat for White-headed Woodpecker, Black-backed Woodpecker, Flammulated Owl at night.
Extended hotspot guide · Seasonal notes
| Month | Activity | Target Species |
|---|---|---|
| Feb–Mar | Lek season | Greater Sage-Grouse at dawn leks |
| Apr–May | Breeding peak | Sage Thrasher, Brewer's Sparrow, Loggerhead Shrike |
| Jun–Jul | Summer | Long-billed Curlew, Ferruginous Hawk |

Columbia River backwaters and wetlands. Sandhill Crane regular in migration. Snow Goose flocks in fall. Sora and Virginia Rail in marsh areas. Breeding Osprey and Black-crowned Night-Heron.
Ponderosa pine and shrubsteppe mosaic near Spokane. Sandhill Cranes breed here — one of the few WA breeding sites. Ruddy Duck, Canvasback, and Redhead on the refuges potholes.
Oregon / Washington border · Raptors, oak woodland, basalt cliffs
The Columbia River Gorge is a place of dramatic contrasts — the wet, moss-draped forests of the western gorge give way to open basalt cliffs and oak woodlands as you move east, creating a transition zone rich in bird life. The gorge is most famous among birders for its outstanding raptor watching. Broughton Bluff and Rowena Crest are among the best hawk-watch sites in the Pacific Northwest.
Hawk watching: October is the prime hawk migration month in the gorge. Count stations at Rowena Crest (OR) and Broughton Bluff (WA) regularly tally thousands of raptors — Sharp-shinned, Cooper's, Red-tailed, and Ferruginous Hawks plus Bald and Golden Eagles.
Outstanding spring wildflower meadows host Western Meadowlark, Horned Lark, and grassland sparrows. In fall, thousands of raptors pass overhead from the plateau viewpoint. Wintering Ferruginous Hawks roost here.
Western gorge old-growth forest with Pileated Woodpecker, Winter Wren, Varied Thrush, and Hermit Thrush. Vaux's Swift roost at Broughton Bluff in September. Stunning waterfall scenery.
Shrubsteppe habitat on the Washington side. Short-eared Owl in fields at dusk. Prairie Falcon on the basalt columns. Chukar Partridge on rocky slopes year-round.
Oak woodland species · West gorge forest · Timing guide
The eastern gorge harbors a disjunct population of Oregon White Oak, creating habitat for several species more typical of California: Acorn Woodpecker, White-breasted Nuthatch, and Western Scrub-Jay grade into the otherwise conifer-dominated flora of the Pacific Northwest.
| Month | Activity | Species |
|---|---|---|
| Feb–Mar | Early migrants | Rufous Hummingbird, swallows |
| Apr–May | Peak migration | Rare warblers, oak woodland breeding |
| Jun–Aug | Breeding | White-throated Swift, Acorn Woodpecker |
| Sep–Oct | Hawk migration | Thousands of raptors daily |
| Nov–Jan | Winter | Ferruginous Hawk, Short-eared Owl |
Portland itself has excellent urban birding with several sites rivaling dedicated nature preserves.
Portland's best urban marsh. Sora, Virginia Rail, Common Gallinule, and year-round Great Blue Heron rookery. Nesting Osprey. Excellent trail system entirely within the city.
One of Oregon's best birding destinations — 12,000-acre wildlife area just 15 miles from downtown Portland. Sandhill Crane in fall; Dusky Canada Geese in spring; Snowy Owl in irruption winters; Tundra Swan in November.
Oregon · Grasslands, oak woodlands, wetlands, farmland
The Willamette Valley stretches 100 miles from Portland to Eugene, flanked by the Coast Range to the west and the Cascades to the east. Its patchwork of native oak woodlands, wet prairies, agricultural fields, and managed wetlands makes it one of Oregon's most diverse birding regions. It is especially famous for its wintering crane spectacle and the rare Dusky subspecies of Canada Goose.
Crane season: Thousands of Sandhill Cranes winter in the valley from November through February. The Finley NWR / Ankeny / Baskett Slough NWR complex provides the best viewing — cranes roost on the wetlands and feed in adjacent fields at dawn and dusk.
Crown jewel of Willamette Valley birding. Dusky Canada Goose flock winters here (primary US wintering site). Sandhill Cranes by thousands Nov–Feb. White-tailed Kite year-round. Acorn Woodpecker in oaks.
Excellent year-round birding. Great Blue Heron rookery visible from Pintail Marsh. Tundra Swan in November. Eurasian Wigeon appears regularly in mixed duck flocks. Virginia Rail in marsh edges.
Large reservoir with seasonally flooded mudflats yielding excellent shorebirding in late summer. Caspian Tern and Forster's Tern nest here. Long-billed Dowitcher in huge flocks in fall.
Season-by-season guide · Rare birds · Owl prowling
| Period | Activity | Don't Miss |
|---|---|---|
| Oct–Nov | Crane arrival | Sandhill Crane flights at dusk; Tundra Swan |
| Dec–Jan | Crane / goose winter | Dusky Canada Goose flocks; Short-eared Owl |
| Feb–Mar | Early spring | Dunsky Goose; early swallows; song sparrows |
| Apr–May | Migration | Rare warblers; shorebirds on flooded fields |
| Jun–Aug | Quiet summer | Breeding Acorn Woodpecker and White-tailed Kite |
| Sep | Shorebirds | Fern Ridge mudflats; pre-migration shorebirds |
Streaked Horned Lark: The endangered Oregon Vesper Sparrow and Streaked Horned Lark both depend on native wet prairie habitat. The Finley and Baskett Slough NWRs support some of the last breeding populations.
The Willamette Valley is one of Oregon's best areas for owling. Fields and farmland host Short-eared and Barn Owls. Forest edge holds Barred, Spotted, and Great Horned Owls.
Short-eared Owl
Hunt open fields at dawn and dusk Nov–Mar. Baskett Slough NWR is the most reliable site. Look for buoyant, floppy wingbeats low over grass.
Barn Owl
Year-round in farm buildings and nest boxes throughout the valley. Drive back roads after dark near Finley and Ankeny. Ghostly white underwings distinctive.
Barred Owl
Expanding throughout valley. Most forest patches now have Barred Owls. Call at dusk. Note: hybridizes with Spotted Owl — check carefully!
Great Horned Owl
Year-round in any woodland. Nesting as early as January in old hawk nests. Calling males establish territories in December — one of the first signs of spring.
Oregon · Rocky headlands, estuaries, offshore pelagic
The Oregon Coast delivers a spectacular combination of accessible rocky headlands, productive estuaries, and world-class pelagic birding just a few miles offshore. Bonaventure-style seabird colonies, Black Oystercatcher territories on wave-swept rocks, and the extraordinary spectacle of 500,000+ shorebirds staging at Bandon Marsh in early May make this a must-visit destination.
Pelagic trips: Depoe Bay and Newport offer excellent chartered pelagic trips August–September. Pink-footed, Flesh-footed, Buller's, and Sooty Shearwaters; Red-necked and Red Phalaropes; and all three jaeger species are possible in a single day offshore.
Active seabird colony on offshore islands visible from the headland. Common Murre, Pelagic Cormorant, Brandt's Cormorant, Pigeon Guillemot, and Tufted Puffin. Stunning coastal hawk watching in fall.
Outstanding mix of estuary, mudflats, and saltmarsh. Four species of dowitcher possible; Western, Least, Sem., and Baird's Sandpipers. Rare shorebirds appear regularly in fall.
Three-arch Rocks visible offshore from Cape Meares — Oregon's largest seabird colony. Rhinoceros Auklet, Common Murre, and Tufted Puffin visible with scope. Ancient Murrelet in fall.
Continued: Southern Oregon coast · Timing · Pelagic guide
The southern Oregon coast from Coos Bay to the California border is less-visited but birder-rich. Port Orford, Gold Beach, and Brookings offer excellent seabird watching and pelagic birding, plus reliable California Gull colonies and wandering California Brown Pelicans.
Oregon's best estuary birding education center. Tidal channels yield all five dowitcher-associated shorebird confusing fall waders. Marbled Godwit, Whimbrel, and Western Sandpiper in September.
Headland sea-watching in August–October for pelagic species. Pink-footed Shearwater, South Polar Skua, and Red-necked Phalarope regularly visible from shore without a boat.
| Month | Activity | Species |
|---|---|---|
| Jan–Feb | Sea ducks | Scoter flocks; Loon concentrations |
| Mar–Apr | Migration begins | Whimbrel, godwits arriving |
| May | Shorebird peak | 450K+ shorebirds at Grays Harbor |

| Aug–Oct | Pelagic peak | Shearwaters, jaegers, phalaropes |
| Nov–Dec | Storm watchers | Fork-tailed Storm-Petrel; rare alcids |
Pelagic trips: Book pelagic trips through VENT (Victor Emanuel Nature Tours) or Westport Seabirds in Washington, or Oregon Pelagic Tours from Newport. August–September offers the greatest species diversity.
Oregon / California border · Wetlands, lakes, agricultural fields
The Klamath Basin is one of the most important migratory bird stopover points in the western United States. Each winter, the lakes, marshes, and agricultural fields of the basin support the largest concentration of wintering Bald Eagles in the lower 48 states — often 1,000 or more individuals. During spring and fall migration, hundreds of thousands of ducks, geese, swans, and shorebirds funnel through this critical Pacific Flyway nexus.
Eagle watch timing: The peak for Bald Eagles is late January through mid-February. USFWS runs free "Eagle Eco-Tour" field trips each February from the Klamath Basin NWR visitor center — advance registration required. Roost counts before dawn are spectacular.
The epicenter of the Klamath eagle spectacle. Drive the auto tour route in your vehicle. Hundreds of eagles visible simultaneously in winter. American Bittern, Sandhill Crane, and waterfowl year-round.
Fall staging peaks in October with over 1 million ducks and geese. Whitefronts, Snow and Ross's Geese, Cackling and Canada Geese in mind-boggling numbers. Peregrine falcons and Prairie Falcons hunting daily.
Largest natural lake in Oregon. American White Pelican massive colony; Western and Clark's Grebe dancing displays in May–June. Osprey everywhere. Snowy Egret and Black-crowned Night-Heron rookeries.
Seasonal timing · Shorebird peaks · Owl marsh prowling
| Period | Activity | Species |
|---|---|---|
| Sep–Oct | Waterfowl arrival | 1M+ ducks/geese at Tule Lake peak |
| Nov | Peak migration | Cackling Goose; Sandhill Crane; Tundra Swan |
| Dec–Feb | Eagle season | 800–1,500 Bald Eagles; Snowy Owl possible |
| Mar–Apr | Spring migration | Cascade of whitefronts and pintail departing |
| May–Aug | Breeding | White Pelican; Clark's Grebe; Sandhill Crane |
Eagle roost watching: The pre-dawn roost flight at Lower Klamath NWR in January–February is one of North America's great wildlife spectacles. Hundreds of eagles depart their roost trees simultaneously at first light. Arrive 45 minutes before sunrise.
Old-growth forest roosting area for 200–400 Bald Eagles in January–February. Watch from Keno-Worden Road at dawn. Eagles departing in misty morning light is an unforgettable sight.
USFWS free Eagle Eco-Tour launches from here in February. Gift shop, spotting scopes, and knowledgeable staff. Current eagle counts posted daily. Ask about active nest locations.
BLM-managed wetland with boardwalk access. American Bittern, Marsh Wren, and Sora year-round. Sandhill Crane breeding in summer. American White Pelican colony nearby on Agency Lake.
Canada · Fraser Delta, Vancouver Island, Greater Vancouver
Coastal British Columbia, though geographically outside the lower 48, is a natural extension of Pacific Northwest birding. The Lower Mainland — encompassing Greater Vancouver, the Fraser River Delta, and Vancouver Island — ranks among the most species-rich birding areas in Canada, routinely recording 300+ species annually.
The Reifel Migratory Bird Sanctuary and surrounding delta farmland support spectacular shorebird and waterfowl concentrations. Snow Bunting and Lapland Longspur are regular in winter on open farmland fields near Ladner and Tsawwassen.
Must-visit: George C. Reifel Migratory Bird Sanctuary (Delta, BC). One of Canada's most-visited bird sanctuaries — Sandhill Cranes, Snow Geese, and up to 26,000 Lesser Snow Geese in November.
Victoria's Clover Point is legendary for rare vagrant sightings, particularly Asian species pushed in by late-fall storms. Esquimalt Lagoon provides excellent winter sea ducks and vagrant gulls. The island's interior has Steller's Jay, Band-tailed Pigeon, and Ruffed Grouse.
The go-to spot for fall rarities in Pacific Canada. Ancient Murrelet, Eep Storm Petrel (rare), and Asian vagrant warblers have appeared here. Excellent year-round for Harlequin Duck and Black Oystercatcher.
Understanding habitat is the key to finding PNW birds efficiently. Each habitat type attracts a distinct bird community regardless of geographic location.

The PNW is a vagrant magnet — its position at the western edge of North America, combined with its coastal exposure and diverse habitats, makes it one of the best places on the continent for rare bird hunting.
Fall (Sep–Nov) — Asian vagrants
Clover Point (Victoria) and Westport, WA are the top spots. Asian warblers, flycatchers, and pipits pushed by northwest storms appear annually. Eurasian Wigeon and Teal mix into flocks.
Winter (Nov–Feb) — Unexpected waterfowl
Check mixed gull flocks carefully — Thayer's, Iceland, and Glaucous Gulls occur. Rare grebes (Clark's, Western hybrids) show up in Puget Sound. Snowy Owls in irruption years.
Spring (Apr–May) — Overshoots
Warblers from the Eastern U.S. occasionally overshoot to the coast. Black-throated Blue, Cape May, and Blackpoll Warblers appear annually in small numbers at Grays Harbor environs.
Pelagic (Aug–Oct) — Oceanic rarities
Short-tailed Albatross, Mottled Petrel, Craveri's Murrelet — all have been found on PNW pelagic trips. The deep waters off the continental shelf edge are the key zone.
Real-time rare bird reporting is essential for chasing rarities. The PNW has excellent listservs and platforms actively used by local birders.

The PNW has several species complexes that regularly challenge even experienced birders. Use these field mark summaries as quick reference.
Western vs. Clark's Grebe
Western: Black cap extends below eye; yellow-green bill; white on face restricted. Clark's: White extends above and around eye; brighter orange-yellow bill; slightly smaller. Both dance together on Klamath and Crater Lake.
Pacific vs. Common Loon (winter)
Pacific: Smaller, brown back pattern, straight bill, pale face patch below eye, often showing "chinstrap". Common: Larger, heavier bill, checkered back (summer), uniform grey cap in winter. Both common on Puget Sound.
Mew vs. Ring-billed Gull
Mew: Smaller, gentle expression, slim bill without prominent ring, rounder head. More common in the PNW. Ring-billed: Heavier bill with clear dark ring, pale yellow eye, squarer head shape. Both common in winter.
Townsend's vs. Hermit Warbler
Townsend's: Yellow face with black cheek patch; streaked sides; common. Hermit: All-yellow head with NO black cheek patch; plain olive back; uncommon. Hybridizes where ranges overlap in Cascades.
Short-eared vs. Northern Harrier
Short-eared Owl: Buoyant, floppy wingbeats; black wrist patches below; hunts at dusk. Northern Harrier: Slower, gliding flight; white rump patch; holds wings in V-shape (dihedral). Both hunt open fields in winter.
Caspian vs. Elegant Tern
Caspian: Largest tern; heavy red bill with dark tip; black cap; raucous call. Breeds at Columbia River. Elegant: Slender orange bill droops; pale below; streaked crest. Post-breeding visitor to OR coast in fall.
Cackling vs. Canada Goose
Cackling: Small, round head, stubby bill, short neck — think "mini Canada". Dusky Canada: Darker breast than other Canada races; found almost exclusively at Finley NWR. Range of sizes within Canada Goose is enormous — compare birds side by side.
Barred vs. Spotted Owl
Spotted: Dark eyes; horizontal barring across chest only; brown with white spots overall. Barred: Dark eyes; strong vertical streaking on lower chest; grayer tone. Hybrids ("Sparred Owls") occur — note mixed patterns as confirmation of hybrid status.
Common vs. Barrow's Goldeneye
Barrow's: Male has crescent-shaped white face spot (common has round); steep forehead; purple gloss on head. Female: more orange bill, rounder head, steeper forecrown. Puget Sound has both; compare in mixed flocks.
Selasphorus Hummingbirds
Rufous: Male orange-rufous back; brilliant orange-red gorget. Allen's: Green back on male — rare PNW vagrant. Calliope: Smallest NA hummingbird; male gorget streaked wine-red on white. East Cascades in summer.
Pacific vs. Winter Wren
Pacific Wren: Western species; complex, slightly lower-pitched song; found in PNW old-growth. Winter Wren: Eastern species very rare on PNW coast. In practice, calls are the best distinction — Pacific Wren's call is a sharp "jimp jimp."
Long-billed vs. Short-billed Dowitcher
Long-billed: Nasal "keek" call; uniform barred tertials; common in PNW winter. Short-billed: Melodious "tu-tu-tu" call; spotted/notched tertials; more common in spring migration. Call is the most reliable distinction.

Birds of the Pacific Northwest — Dunn & Alderfer
Regional field guide with photos. Excellent for trip focus — covers WA, OR, and coastal BC in one volume.
The Shorebird Guide — O'Brien, Crossley, Karlson
Essential companion for Grays Harbor, coastal estuaries, and Klamath Basin. Unmatched photo sequences of difficult shorebirds in all plumages.
Seabirds: An Identification Guide — Harrison
Classic reference for PNW pelagic species. Covers all tubenoses, alcids, and jaegers likely on Oregon or Washington pelagic trips.
eBird by Cornell Lab
Essential for finding recent species at specific sites. Filter by hotspot, county, or species. "Explore" function shows where targets have been found recently.
Merlin Sound ID (Cornell)
Real-time bird sound identification. Download PNW packs offline. Invaluable in PNW forests where birds are heard before seen. Also has Photo ID mode.
AllTrails / Gaia GPS
Trail navigation essential for Cascade and Olympic Peninsula sites. Download maps offline — cell service is nonexistent in many top birding locations.
Weather.gov Marine Forecasts
Essential for planning pelagic trips. Westport / Newport offshore conditions change rapidly. Never book a pelagic without checking the 3-day marine wind forecast.
The Pacific Northwest is both a birding paradise and a region under severe ecological pressure. Understanding conservation issues helps birders advocate for the habitats that make this region exceptional.
Spotted Owl — Threatened
Old-growth logging reduced habitat by 90%+ since 1900. Barred Owl invasion now the primary threat. USFWS managing experimental Barred Owl removal programs.
Marbled Murrelet — Threatened
Nests in old-growth trees — logging eliminated 90%+ of nesting habitat. Gillnet bycatch in marine waters remains a significant mortality source alongside corvid nest predation.
Greater Sage-Grouse — Candidate
WA population is one of the rarest vertebrate populations in the state — fewer than 1,000 individuals. Sagebrush conversion to agriculture and energy development are primary threats.
Streaked Horned Lark — Threatened
Less than 3,000 individuals remain in the Willamette Valley and Columbia River islands. Native wet prairie habitat has been almost entirely converted to agriculture.
Responsible birding directly contributes to conservation through data collection, advocacy, and funding via ecotourism spending.
Submit eBird Checklists
Every checklist you submit contributes to the world's largest ornithological database — driving research, conservation policy, and site protection decisions.
Support Local Audubon Chapters
Cascade Audubon, Portland Audubon, Klamath Bird Observatory — each does critical local conservation work. Membership dollars fund habitat restoration and advocacy.
Follow Leave No Trace Protocol
Never broadcast owl calls near active nests. Stay on designated trails in sensitive habitats (shorebird nesting beaches, alpine meadows). Respect closure signs at seabird colonies.
Spend Locally
Birding tourism generates significant economic value for gateway communities near refuges and parks. Spend at local businesses, stay at local lodges, support the economies that protect bird habitat.

America the Beautiful Pass ($80/year) covers entrance fees at all National Parks and NWRs in the guide — an excellent investment for multi-site PNW trips.
The Pacific Northwest will surprise you. Even the most seasoned birder returns home with unexpected sightings, humbled by species they missed, and already planning the next trip. That's the magic of it.
The rain is part of the experience — not an obstacle to it. The misty mornings at the Hoh when a Spotted Owl answers back, the Pre-dawn moment at Tillamook when 10,000 Dunlin lift off the flats in synchrony, the January morning at Lower Klamath when 600 Bald Eagles leave their roosts in a dark river of wings — these are the moments that birders return to the Pacific Northwest to find again and again.
We hope this guide serves you well in the field. Good birding.
