At a glance
North Wales has outstanding wildlife across its different habitats — red kites (common throughout the region, reintroduced to the Conwy Valley in the early 2000s), chough at South Stack Anglesey (an RSPB reserve), puffins on Puffin Island (boat trips from Beaumaris), ospreys at RSPB Glaslyn in Snowdonia (April–August), and red squirrels on Anglesey (last viable population in Wales, best seen at Newborough Forest). The peregrine falcon is widespread on mountain crags and coastal cliffs.
Wildlife Highlights of North Wales
The red kite's return to North Wales is one of the most visible conservation successes of recent decades. Extirpated from England and most of Wales by the 19th century (trapped, shot, and poisoned by gamekeepers and farmers), the red kite survived only in the mid-Wales hill country through a single, slowly recovering population. The reintroduction programme that began in the early 1990s brought birds from that surviving Welsh population and from continental Europe to sites across England and Scotland; North Wales received its own reintroduced population in the Conwy Valley in the early 2000s. The kites have spread across the region since — a drive through the Gwydyr Forest or the Clwydian Range is now likely to produce one of these large, buoyant, fork-tailed raptors soaring on the updrafts. The bird's rehabilitation, from a species on the edge of extinction in Britain to an everyday North Wales sighting within 30 years, is genuinely remarkable.
The chough — the red-billed, red-legged crow that is the heraldic symbol of Wales and of several Welsh towns — has its stronghold on the Anglesey and Llŷn Peninsula cliffs. South Stack, the RSPB reserve on the northwest corner of Anglesey, has the most accessible chough watching in North Wales — the birds can often be seen feeding on the close-cropped grass above the clifftop path, probing the sward for invertebrates with their curved red bills. The RSPB visitor centre has identification guides and, in spring and summer, volunteers with telescopes available to help visitors find the birds. The chough's raucous "chee-ow" call is diagnostic once learned; hearing it above a Welsh cliff is one of those sights-plus-sounds that make wildlife watching genuinely memorable.
The ospreys at Glaslyn represent a different kind of wildlife story. Ospreys bred in Britain until the early 20th century, when persecution and egg-collecting eliminated them; they returned to Scotland via natural recolonisation in 1954 and have gradually spread south. The pair that settled at Glaslyn in Snowdonia in 2004 — later named Monty and Nora, then followed through successive breeding seasons — brought osprey breeding back to Wales for the first time in 400 years. The RSPB observation point at Pont Croesor in the Glaslyn valley allows visitors to watch the nesting platform from a respectful distance in spring and summer; the livestream on the RSPB website means the nest is watched by wildlife enthusiasts worldwide throughout the breeding season.

Frequently asked questions
North Wales has exceptional wildlife across its different habitats. Upland Snowdonia: peregrine falcon, red grouse, merlin, ring ouzel, wheatear, and mountain hare (rare). Anglesey coast: chough (red-billed crow) at South Stack and Penmon, puffins, razorbills, and guillemots on Puffin Island and South Stack cliffs (spring–summer), harbour porpoise in the Menai Strait. Lowland and forest: red kites (reintroduced to the Conwy Valley and now widespread across North Wales), red squirrels (Anglesey — the last viable red squirrel population in Wales), otters on lowland rivers. Glaslyn valley (Snowdonia): ospreys nesting from April–August (RSPB Glaslyn livestream available).
Red kites were reintroduced to the Conwy Valley in the early 2000s and have spread across North Wales — they are now relatively common across the region and can be seen anywhere from the Conwy Valley to the Clwydian Range. The best reliable sightings are at feeding stations: the most accessible is the Bwlch Nant yr Arian RSPB reserve (near Aberystwyth, south of the region) but kites are regularly seen without visiting a feeding station — scanning any upland area of the Conwy Valley or Gwydyr Forest from a viewpoint is likely to produce kite sightings. Red kites are large, distinctive birds — their forked tail and russet-red plumage are unmistakable in flight.
Puffin Island (Ynys Seiriol) off the eastern tip of Anglesey has the largest puffin colony in North Wales — accessible only by boat trip from Beaumaris (spring to summer; advance booking recommended). South Stack on the northwest coast of Anglesey has puffins on the cliff ledges (spring–summer; the RSPB visitor centre has telescope views). Skomer Island (Pembrokeshire) is outside North Wales but has the most spectacular puffin colony in Wales — 6,000+ breeding pairs — and is worth a day trip if puffins are your priority. North Wales puffins are present from approximately April to early August.
Yes — ospreys have nested in the Glaslyn valley in Snowdonia since 2004. The RSPB Glaslyn project monitors the nesting pair (and their offspring, some of which have returned to breed) from an observation point near Pont Croesor (reached by a short walk from the car park). The ospreys are present from April to August; the livestream camera is available on the RSPB website during the nesting season. Glaslyn ospreys are among the most watched breeding wildlife in Wales and represent one of the most significant conservation successes in Snowdonia in recent decades.
Anglesey has the last viable red squirrel population in Wales — the island's isolation from the mainland (the Menai Strait) and a sustained grey squirrel control programme have allowed the native red squirrel to persist where it has been extirpated from the rest of Wales and most of England. The best locations for red squirrel sightings on Anglesey are the conifer forests at Newborough (near the beach car park area) and Pentraeth Forest. Red squirrels are elusive — morning visits in early spring (March–April) before the leaf canopy reduces visibility give the best chance. The Anglesey Red Squirrel project website has current sighting reports.
The North Wales coast and islands have excellent seabird populations in spring and summer. South Stack (northwest Anglesey) has accessible cliff ledges with razorbills, guillemots, puffins, kittiwake, and fulmar — the RSPB visitor centre has telescope views of nesting ledges. Puffin Island (eastern Anglesey) has puffins, cormorant, guillemot, and razorbill; boat trips from Beaumaris. Bardsey Island (Llŷn Peninsula tip) has shearwaters, storm petrels, and chough — day trips from Aberdaron when conditions allow. The Great Orme headland (Llandudno) has a breeding seabird colony with razorbills and kittiwake visible from the cliff paths.
