Blasket Islands Pelagic Birding

The Blasket Islands Eco Marine Tours Pelagic Birding trip is a dedicated eight-hour offshore seabird expedition departing from Ventry Pier on the Dingle Peninsula in Co. Kerry, a wild and remote stretch of the Irish Atlantic coast four miles west of Dingle town on the Slea Head Drive. The trip is operated by skipper Mick Sheeran, who grew up on and has an intimate connection with Great Blasket Island — the largest and most celebrated of the Blasket archipelago, inhabited until its dramatic evacuation in 1953 and now one of Ireland's most evocative wild places. Sheeran's knowledge of the waters west of the Blaskets, accumulated over a lifetime at sea in this corner of Co. Kerry, underpins the navigational strategy for each pelagic, adjusting to the day's conditions, tidal streams, and the shifting fronts where warmer Atlantic surface water meets cooler shelf-edge upwelling.

The route heads west from Ventry Pier for approximately two hours, transiting the spectacular Blasket Sound — the deep, tide-scoured channel separating the Dingle Peninsula from the Blasket archipelago — before reaching oceanic water beyond the 100-metre depth contour. The vessel then spends approximately four hours working the optimum pelagic area before making the two-hour return passage. This commitment to reaching genuinely deep Atlantic water is what distinguishes the Blasket Islands Pelagic from coastal wildlife cruises; the target species are true oceanic birds whose presence close inshore is always incidental, and which concentrate predictably only in the water mass that forms the western edge of the European continental shelf.

The season runs from mid-August to mid-October, timed specifically around the peak of southward seabird migration past the southwest tip of Ireland. The primary targets are the storm-petrel species that concentrate off Kerry in this window: Wilson's Storm-petrel, a trans-equatorial migrant breeding in Antarctica and the sub-Antarctic that passes through Irish Atlantic waters in July and August, and Leach's Storm-petrel, a North Atlantic breeder whose post-breeding dispersal generates westerly-weather movements off Ireland from August onwards. Both species are reliably encountered on the trip during suitable conditions. Red-necked Phalarope — a delicate, needle-billed wader that spends the non-breeding season at sea, spinning in tight circles as it picks surface invertebrates from oceanic drift lines — is a regular target and a particularly photogenic species at close range.

The larger shearwaters that dominate Atlantic surface waters in late summer are well represented on the trip. Sooty Shearwater, the abundant dark shearwater that breeds in the South Atlantic and transequatorial Pacific and migrates through European waters in enormous numbers, is typically the most numerous large shearwater, with autumn counts regularly reaching the hundreds or thousands. Balearic Shearwater, a Critically Endangered Mediterranean breeder whose entire population migrates around the Iberian Peninsula and north to Irish and British waters between August and October, appears with regularity; this is one of the best opportunities in Ireland to encounter this threatened species at close range. Manx Shearwater is abundant throughout. All three breeding European skua species — Arctic, Long-tailed, and Great — are regular, with the rarer Long-tailed Skua most reliably seen during the late August window when juveniles concentrate in offshore Atlantic waters ahead of their southward migration.

The surrounding Blasket Islands archipelago is itself a Special Protection Area (SPA) holding internationally significant seabird colonies, and the dramatic volcanic sea stacks, arches and cliff scenery of the Dingle Peninsula coastline traversed during the transit provides a striking backdrop even before the open-ocean species begin to appear.
