Canada sits at the meeting point of two of the Northern Hemisphere’s great ocean systems. On the Pacific coast, the California Current carries cold, nutrient-rich water south from British Columbia through Oregon, California, and Baja California — a conveyor belt that drives one of the planet’s most productive seabird ecosystems. On the Atlantic coast, the cold Labrador Current flows south from the Arctic past Newfoundland and Nova Scotia, and the Grand Banks — the shallow submarine plateau southeast of Newfoundland — concentrate shearwaters and storm-petrels in numbers that once fed the great trans-Atlantic fishing fleets.
The two coasts are about as different as seabird environments get. BC’s offshore waters deliver albatrosses, Sooty Shearwaters in the hundreds of thousands, and a remarkable alcid diversity. Atlantic Canada’s late summer is defined by Great and Sooty Shearwaters, Leach’s and Wilson’s Storm-Petrels, and a close-inshore seabird colony scene that’s accessible from small boat excursions. Timing your visit correctly is everything.
British Columbia: April Through November
British Columbia’s pelagic season runs from April through November, with a clear mid-season peak. The waters off Vancouver Island’s outer coast — particularly around Tofino and the open Pacific beyond Clayoquot Sound — are the primary departure point for dedicated pelagic birding in Canada.
April to June: Spring Return
April marks the beginning of the offshore season in BC. Pink-footed Shearwaters are among the first birds to arrive, returning from their wintering grounds in coastal Chile. By late April, Pink-footeds are appearing regularly on trips from Tofino, and they remain present throughout the productive season. Their combination of large size, pale underparts, and dark pink bill makes them distinctive among the shearwaters that use BC waters.
Black-footed Albatross is the headline bird of any BC offshore trip, and spring is a reliable time to find one. This dark, coffee-coloured albatross breeds in the northwest Hawaiian Islands but ranges freely across the North Pacific, following fishing boats and feeding concentrations along the continental shelf edge. It is present year-round in BC waters but peaks in spring and fall. April through June departures from Tofino regularly produce one to several birds, banking on stiff southwest winds or sitting on the water in small groups near the shelf break.
Fork-tailed Storm-Petrels return to their breeding islands in late April and May. These pale, distinctive storm-petrels — grey above and below, with a forked tail and fluttery flight — breed on Triangle Island and other offshore BC archipelagos. From May onward, they appear on departures with increasing regularity, often in small groups skimming the wave troughs ahead of the boat.
The alcid community is active throughout spring. Rhinoceros Auklets, which breed on offshore islands and haul fish to their colonies in their distinctive bill pouches, are abundant year-round. Pigeon Guillemots breed on rocky headlands and are visible from shore and boat alike. Marbled Murrelets, cryptic seabirds that nest in old-growth coastal forest and commute to sea daily, appear in small numbers throughout the season.
July to September: Peak Season
This is the window to prioritize if you have one trip to take from Tofino. The combination of species diversity, sheer numbers, and weather windows makes the late-summer period the best overall experience.
Sooty Shearwaters are the defining bird. They breed on sub-Antarctic islands in the Southern Hemisphere and migrate north to the North Pacific in enormous numbers during the southern winter. In peak August and September, flocks of tens of thousands of Sooty Shearwaters are not unusual off Tofino — the California Current’s upwelling creates dense prey patches that hold the birds in concentrations visible from shore on exceptional days. The spectacle of a Sooty Shearwater feeding flock, thousands of birds wheeling and plunge-diving over a school of fish, is one of the more remarkable wildlife events on the Pacific coast.
Buller’s Shearwater arrives in late July and peaks in August and September. This is arguably the most elegantly marked shearwater in the world — sharp black-and-white plumage with a distinctive black M-shaped wing pattern and clean white underparts. It breeds in New Zealand’s Hauraki Gulf and ranges across the North Pacific, reaching BC waters in late summer. Buller’s is not always common on every trip, but a fall departure from Tofino is the best single opportunity to see it in North America.
Flesh-footed Shearwater, a large, all-dark shearwater with a pink-and-black bill, is less common but appears regularly from July through October. Pink-footed Shearwaters continue in good numbers through the summer.
Jaegers are a reliable and conspicuous feature. Pomarine and Parasitic Jaegers arrive from July, harassing shearwaters and phalaropes. Long-tailed Jaeger — the most elegant of the three, with elongated central tail streamers and cleaner plumage — is annual in small numbers on fall trips, migrating south from its Arctic breeding grounds. Red-necked and Red Phalaropes concentrate over feeding areas and provide prey for the jaegers.
Fork-tailed Storm-Petrel is at peak abundance in summer, breeding on offshore islands and appearing regularly in small groups. Leach’s Storm-Petrel is also present, a darker, longer-winged bird with a more erratic, bounding flight. On calm days, storm-petrels gather in feeding groups behind the boat when chum is deployed; this is one of the few places on the continent to compare Fork-tailed and Leach’s Storm-Petrels side by side.
October to November: Fall Migration Peak
October is the best single month for alcid diversity. Ancient Murrelet migration peaks in October and early November, with large flocks moving south along the coast from their breeding colonies on Haida Gwaii and the northern BC islands. This small, fast-flying murrelet — black hood, white underparts, grey back, and a distinctive white stripe over the eye — doesn’t nest in the lower 48 states and is primarily a winter visitor south of BC. Tofino is at the heart of its migration route, and October departures can produce significant numbers.
Shearwater numbers decline from their September peak but remain respectable through mid-October before dropping off sharply. The late-season overlap of Sooty, Pink-footed, Buller’s, and occasionally Short-tailed Shearwaters in early October makes this transition period interesting.
Thick-billed and Common Murres increase in October as Alaskan breeders begin moving south. Horned Puffin, primarily an Alaskan bird, is a scarce possibility on fall trips from the north BC coast. Cassin’s Auklet, a tiny, round alcid that breeds in the millions on offshore BC islands, remains present through fall.
December to March: Winter Alcids
Winter trips from Tofino are rougher and less predictable, but the species list includes birds absent in summer. Ancient Murrelets remain in BC waters through winter, and alcid concentrations close to the sound can be productive. Short-tailed Albatross, once nearly extinct from feather hunting and now slowly recovering to perhaps 7,000 birds, has been recorded in BC offshore waters and represents the genuine rarity of the region — possible on any winter departure but never expected. Black-footed Albatross occasionally appears through winter. Northern Fulmar is more regular in winter than in summer.
Atlantic Canada: Nova Scotia and Newfoundland
Atlantic Canada’s pelagic birding operates on a different rhythm and through a different infrastructure than BC. Dedicated pelagic birding products are fewer, and the accessibility of offshore water varies significantly by province. But the sheer abundance of birds in summer — particularly on and near the Grand Banks — rivals anything on the Pacific coast.
June to August: Storm-Petrel Season in Nova Scotia
The Bay of Fundy and the waters off southwestern Nova Scotia come alive in late June and July. Leach’s Storm-Petrel breeds in enormous colonies on islands off the Nova Scotia coast, including Seal Island and Bon Portage Island. On calm summer nights the colonies are audible from shore — a churring call that has given this species part of its folklore. During the day, storm-petrels commute offshore to feed, and small-boat trips from southwestern Nova Scotia ports can produce significant numbers on good days.
Wilson’s Storm-Petrel, which breeds in the sub-Antarctic and migrates to the North Atlantic for the northern summer, arrives from June and peaks in July and August. In Bay of Fundy waters and offshore Nova Scotia, both Wilson’s and Leach’s Storm-Petrels can be present simultaneously — a useful comparison since they have subtly different flight styles and undertail patterns.
Northern Gannet is present throughout summer from its colony on Bonaventure Island, Quebec, visible from the Gaspé Peninsula but ranging widely through the Gulf of St. Lawrence and offshore Atlantic waters. Great Cormorant, Double-crested Cormorant, Atlantic Puffin, Razorbill, Common Murre, and Black Guillemot all breed on islands along the Nova Scotia coast and are visible from the water throughout summer.
July to August: Grand Banks Shearwaters
The Grand Banks — the continental shelf southeast of Newfoundland — are among the most productive marine areas in the North Atlantic. Cold Labrador Current water meeting warmer offshore conditions creates upwelling that concentrates fish and, in turn, seabirds. From late July through September, Great Shearwaters and Sooty Shearwaters gather over the Banks in large numbers, along with Manx Shearwaters, Wilson’s Storm-Petrels, and occasional Cory’s Shearwaters tracking north.
The challenge for birders is access. Dedicated pelagic birding trips to offshore Newfoundland waters are not widely available, but whale-watching operators from Trinity Bay on Newfoundland’s Bonavista Peninsula and from St. John’s provide some access to the inshore and shelf waters. Ferry crossings from Nova Scotia to Newfoundland also pass through productive shearwater and storm-petrel habitat in late summer.
Autumn Seabird Migration
September and October bring southbound migrants through Atlantic Canada. Sabine’s Gull, an Arctic breeder, moves through offshore waters in small numbers. South Polar Skua, Pomarine and Parasitic Jaegers, and Red-necked Phalaropes add to the diversity. Atlantic Puffins, Razorbills, Common Murres, Dovekies, and Black-legged Kittiwakes all move through as they disperse from their breeding colonies to offshore winter quarters.

Finding Canada Pelagic Trips
The Pelagic Directory currently lists trips operating from British Columbia’s Pacific coast. The Whale Centre Tofino Pelagic is the primary dedicated pelagic birding departure from Canada, operating from Tofino into the open Pacific offshore of Clayoquot Sound.
Browse all Canadian trips in the Canada directory.
Atlantic Canada’s pelagic birding is less formally organized than BC’s, with seabird and whale-watching operators providing the most accessible routes to offshore waters. Booking trips well in advance for the July–September peak season is advisable, particularly for the BC offshore, where demand from visiting birders outstrips available spaces from late summer onward.
