Birdwatching in the Azores: Seabird Cliffs and the Priolo

Two Very Different Birds, Two Very Different Habitats

Most visitors who ask about wildlife in the Azores are really asking about whales and dolphins, and the archipelago’s boat operators are built around exactly that. Birdwatching here is a quieter, more deliberate pursuit, and it splits into two almost unrelated experiences that are easy to blur together simply because both, in a loose sense, happen “near the coast.”

The first is seabird watching: colonies of shearwaters, storm-petrels, terns and gulls that nest on cliffs, islets and rocky headlands across several islands, most active from late spring to early autumn and most visible at dusk, when adults stream back to their burrows after a day feeding far out over the Atlantic. This is a maritime bird community, tied to the ocean for food and to steep, often inaccessible ground for nesting.

The second is entirely different: the priolo, an endangered finch found only in a small block of native laurel forest around Pico da Vara in the far east of São Miguel. The priolo has no relationship to the sea. It lives in dense, damp, high-altitude woodland, feeds on native plant seeds and berries, and is, ecologically, about as far from a sperm whale or a shearwater as an Azorean animal can get.

Treating the two as one “coastal wildlife” outing is the single most common mistake made by visitors planning a birding day here, and it is worth separating clearly before you plan your trip: if you came for cetaceans, this is not that page — see the site’s dedicated guides on whale watching in the Azores and swimming with dolphins instead.

Seabird Cliff Colonies: Who Nests Where

The Azores hold an internationally significant share of the world’s breeding seabirds, largely because the islands’ remoteness and volcanic cliffs offer predator-limited nesting ground far out in the North Atlantic. The species you are most likely to encounter, and where, break down roughly as follows.

Cory’s shearwater (cagarro in Portuguese) is by far the most numerous and most conspicuous species, breeding in burrows and rock crevices on cliffs and islets across most of the archipelago. Colonies exist on São Miguel, on the islet off Vila Franca do Campo, on Faial, on Graciosa, on Corvo and on the uninhabited Ilhéus das Formigas between São Miguel and Santa Maria. Their evening return to the colony, when hundreds of birds arrive low over the water calling to locate their burrow, is the single most reliable seabird spectacle in the islands during summer.

Monteiro’s storm-petrel, one of the smallest seabirds in the North Atlantic, was only formally described as a distinct species in 2008 and breeds on a handful of islets around Graciosa. Unusually, it shares its nesting islets with the closely related band-rumped storm-petrel, but the two species avoid competing directly by breeding in different seasons — a rare case of the same rock supporting two nearly identical birds at different times of year.

Manx shearwater and the smaller Barolo shearwater (a form sometimes called little shearwater) breed in more scattered, harder-to-access sites, generally on steeper cliff faces and smaller islets than Cory’s shearwater favours.

Common tern and, more rarely, roseate tern nest on low rocky islets and shingle in a handful of protected sites, generally in far smaller numbers than the shearwaters and requiring more precise timing and location knowledge to find.

Bulwer’s petrel and the local, notably dark subspecies of yellow-legged gull round out the regularly encountered seabird community, the gull being the one species you will see everywhere, every month, with no need for planning at all.

Seabird Species at a Glance

Species	Where to look	Typical season	How you’ll notice it
Cory’s shearwater	Cliffs and islets archipelago-wide, incl. Vila Franca islet, Faial, Corvo	Late April to October, peak Jun–Aug	Mass evening return flights, loud calling after dusk
Monteiro’s storm-petrel	Graciosa islets	Seasonal, segregated from band-rumped petrel	Rarely seen without a specialist boat or ringing team
Band-rumped storm-petrel	Graciosa and other islets	Complementary season to Monteiro’s petrel	Same as above; identification needs an expert
Manx / Barolo shearwater	Scattered cliff and islet sites	Spring–autumn	Smaller, faster flight than Cory’s shearwater
Common / roseate tern	A few protected islets and shingle sites	Late spring–summer	Small, agile terns diving close inshore
Yellow-legged gull (Azorean form)	Everywhere, all islands	Year-round	The default gull silhouette on any cliff or harbour

Because most of the true colonies sit on cliffs, offshore islets or ground that is protected and closed to casual visits, the most dependable way to see the shearwaters and petrels well is from the water rather than from land, ideally with someone who already knows where the colonies and feeding rafts are that week.

a small-boat outing led by a biologist who tracks the shearwater and storm-petrel colonies day to day is the most direct route to close seabird sightings without months of local scouting, and it doubles as a good introduction to the wider marine ecology covered in the site’s geopark guide.

The Priolo: An Endangered Finch Found Nowhere Else

The priolo, known internationally as the Azores bullfinch (Pyrrhula murina), is one of the rarest passerines in Europe and the archipelago’s only endemic land bird. Its entire world range is a single block of native forest in the hills above the eastern tip of São Miguel, centred on Pico da Vara and the neighbouring Serra da Tronqueira, and it does not occur, has never occurred, and cannot simply be found by chance on any other Azorean island.

For decades the species was pushed toward extinction by two connected problems: the spread of invasive plants — particularly a fast-growing shrub that choked out the native understorey the priolo depends on for food — and the resulting loss of the specific native fruiting and seeding plants it needs across the year. By the late twentieth century the population had fallen to a level that made the species one of the most threatened birds in Europe.

Sustained habitat restoration work, led over recent decades by Portuguese conservation organisation SPEA in partnership with regional authorities, has focused on clearing invasive vegetation and replanting native laurel-forest species across the priolo’s remaining range. The result has been one of the more encouraging conservation recoveries in the region: numbers have grown substantially from their historic low point, though the species remains classified as threatened and its range is still confined to this one corner of one island.

What Kind of Habitat You’re Actually Looking For

The priolo lives in laurissilva — native Azorean laurel forest — a damp, shaded, often misty habitat dominated by trees and shrubs found nowhere outside Macaronesia. This is not the open pasture, hydrangea hedgerow or crater-lake scenery most visitors associate with São Miguel; it is closed-canopy, frequently wet forest at moderate altitude, reached on signed trails rather than by road. If your image of an Azorean nature outing is a coastal viewpoint or a crater lake, the priolo’s forest will look and feel like a different island entirely.

Practical points worth knowing before you go:

• The bird is far easier to hear than to see. Its call is the first and often only clue to its presence in dense understorey, which is exactly why a guide or biologist who already knows the call is such an advantage over a solo, unaided visit.
• Early morning is generally the calmest and most productive time, before wind picks up in the exposed upper sections of the trail network.
• Weather at this altitude changes fast even by Azorean standards; heavy mist or rain can make a visit unrewarding, so build flexibility into your schedule rather than a single fixed slot.
• This is genuinely a forest hike, not a casual roadside stop — pair the visit with the site’s broader notes on hiking trails on São Miguel and on how the islands’ trails are graded before committing to a route.
• The nearby town of Povoação and the wider Nordeste area are the practical bases for a priolo outing, though this guide is about the bird and its forest, not a tour of either town.

Planning a Dedicated Birdwatching Trip

A birding day in the Azores rewards planning more than most other activities on the islands, largely because the two headline targets — seabird colonies and the priolo — sit at opposite ends of the archipelago’s geography and ecology, and neither can be rushed.

Timing. Late spring through summer is the strongest window for seabirds, when colonies are active and evening return flights are at their most reliable; the priolo, by contrast, can in principle be looked for across most of the year, though a calm, dry morning always beats a windy or misty one regardless of season. Check the site’s seasonal weather notes before locking in dates, since a forecast that looks fine at sea level can be socked in with cloud a few hundred metres higher around Pico da Vara.

Gear. Binoculars are close to mandatory; a spotting scope helps considerably for distant cliff colonies and islet views but is optional for the forest trails. Bring layers and proper footwear regardless of season — the priolo’s forest is reliably muddy, and clifftop viewpoints for seabirds are often exposed and breezy even when the town below is calm. The site’s general packing list covers the rest of the basics.

Getting around. Because the priolo’s range sits in a specific, somewhat remote corner of eastern São Miguel and the best seabird viewpoints are scattered across multiple coastal sites, a rental car gives far more flexibility than relying on scheduled transport — see the notes on car rental and general driving conditions on the islands before you commit to a self-drive itinerary.

Guides matter more here than for most Azorean activities. Both target species reward local knowledge in a way that scenery-focused outings do not: shearwater colonies shift with feeding conditions week to week, and the priolo’s call is not something most visitors can pick out unaided on a first attempt. A specialist trip, or at minimum a conversation with a local guide before setting out independently, will change the outcome of your day far more than it would for, say, a crater-lake viewpoint.

If a full week is on the table rather than a single day, the site’s five-day São Miguel itinerary gives a sense of how a birding morning around Pico da Vara can sit alongside the island’s other highlights without feeling rushed.

Fitting Birdwatching Around the Rest of an Azorean Trip

Because the priolo and the seabird colonies are narrow, specialist targets, most visitors treat a birding morning as one focused block within a broader trip rather than the trip’s entire theme. A few pairings work naturally:

A biologist-led seabird excursion, such as the small-group marine trip that tracks shearwater and storm-petrel activity with an onboard biologist, is the closest thing on this coast to a dedicated seabird outing, and it fits well as a half-day alongside a forest morning spent looking for the priolo.

Anyone spending time on the water for a day of inshore and offshore fishing off the islands will often pass active shearwater feeding rafts without looking for them — a useful bonus rather than a substitute for a dedicated seabird trip.

A calm evening on the water, such as a late-afternoon boat trip timed around sunset over the Atlantic, overlaps neatly with the hour when shearwaters are streaming back toward their cliff colonies, even on an outing that isn’t explicitly built around birds.

For a change of pace away from forest trails and cliff edges, a walk through a landscaped botanical garden in Ponta Delgada is a gentler option on a day when weather rules out the exposed upper trails around Pico da Vara, and it still rewards anyone happy to notice smaller garden birds along the way.

None of these substitute for the two core experiences described above, and none of them will put you in front of a priolo — that still means a forest trail, a quiet morning, and ideally someone who already knows the call.

Frequently Asked Questions About Azores Birdwatching

What is the priolo and where can I see it?

The priolo, or Azores bullfinch (Pyrrhula murina), is a small finch found nowhere on Earth except a patch of native laurel forest around Pico da Vara and the Serra da Tronqueira in eastern São Miguel. It does not occur on any other Azorean island, and it is a forest bird, not a coastal or marine species.

When is the best time to see seabird colonies in the Azores?

Most burrow- and cliff-nesting seabirds, Cory’s shearwaters especially, are present from roughly April to October, with peak activity and evening return flights in June, July and August. Winter is largely silent at the colonies, as the birds have dispersed out over the open Atlantic.

Do I need a guide to find the priolo?

You do not strictly need one, but a local guide or biologist sharply improves your odds. The priolo is shy, moves quietly through dense laurel understorey, and is far easier to hear than to see; someone who knows its call and the current feeding areas will save you hours of quiet waiting.

Which islands have the best seabird colonies?

São Miguel, Faial, Graciosa and Corvo all hold significant colonies on cliffs and offshore islets, and the uninhabited Ilhéus das Formigas and the islet off Vila Franca do Campo are especially important for breeding shearwaters and terns. Numbers and access vary a great deal by island and by season.

Is birdwatching in the Azores different from whale watching?

Yes, and it is worth keeping the two apart. Whale and dolphin trips go out to sea to find cetaceans; seabird watching mostly happens from clifftop viewpoints, islet boat passes or forest trails, and the priolo specifically is a landlocked, forest-dwelling species with no connection to the ocean at all.

What should I bring on a birdwatching trip in the Azores?

Binoculars are essential, since much of the priolo’s presence is given away by call before sight. Add waterproof layers, sturdy footwear for muddy forest trails, and patience: Azorean weather changes quickly, and both seabirds and the priolo reward quiet, unhurried observation over a fast checklist approach.

Can I combine birdwatching with a boat tour?

Yes. A biologist-led marine excursion focused on seabirds is the most direct way to see shearwaters and storm-petrels close to their colonies and feeding rafts, and several general boat trips around the coast will pass active seabird cliffs even when birds are not the main subject of the tour.

Is the Pico da Vara reserve open to the public year-round?

The protected forest around Pico da Vara is accessible on marked trails through most of the year, though Azorean weather at this altitude turns quickly, and cloud or heavy rain can make a visit unrewarding or the trail unsafe. Mornings tend to be calmer and give the best chance of activity before birds go quiet in the heat or wind of the day.
