The Irish Whale and Dolphin Group (IWDG) has appealed for the public to keep a look-out after a spate of marine wildlife strandings reported in recent days.

Half of the six reports were live strandings, the group says, but only one animal was successfully returned to the water.

In Galway, a common dolphin live stranded with serious injuries but died shortly after IWDG members arrived at the scene.

Another common dolphin live stranded at Mulranny in Co Mayo. Local woman Catherine Hanley, who reported the stranding, managed to refloat this dolphin with her group and it has not been seen since.

In Co Donegal, a “very emaciated” Cuvier’s beaked whale live stranded at Dooey Beach in Downings, on the Rosguill peninsula, but died shortly after.

Elsewhere, the remains of three more cetaceans were reported around the coast in recent days.

In Rathmullen, Co Donegal, the carcass of a common dolphin appears to match video of a dolphin swimming in the area the previous day, suggesting a live stranding.

At Greenore in Co Louth, at the mouth of Carlingford Lough, a common dolphin in “very fresh condition” was reported to the local IWDG group.

And in Passage East, Co Waterford, a carcass in “very poor” condition has been logged as “dolphin species” as its advanced state of composition made further identification impossible.

The IWDG appeals for the public to report all strandings “so we respond immediately and monitor the status of our whales and dolphins”.

The first case of a grey seal predation on a harbour porpoise in Irish waters has been confirmed, the Irish Whale and Dolphin Group (IWDG) says.

Video of the incident off Clogherhead in Co Louth on Sunday 14 November was submitted to the marine wildlife charity. It appears to show an adult grey seal with a porpoise calf in its mouth and attempting to drown its victim before feeding on it.

Sightings officer Pádraig Whooley said there was “little doubt” as to what was occurring in the footage, which can be seen below. Some viewers may find the video disturbing:

Andy Smith, who was fishing on the pier in Clogherhead when he shot the video, said: “We initially saw the mother and baby about 200m out to sea but about 20 minutes later the seal surfaced with the baby porpoise in its mouth.

“It was quite violent and bloody. Thankfully there were no kids around to witness it. Nature raw in tooth and claw I suppose.”

Whooley added that the incident, while rare, is not without precedent. A paper published in the journal Marine Mammal Science in 2014 offered the first evidence of grey seal predation on harbour porpoise in the English Channel and North Sea.

“However, this behaviour has never before been documented in Irish waters, which is surprising given the large populations we have of both coastal species,” he said.

The incident now opens questions as to whether this is indeed new behaviour from an Irish seal “or one that has simply never before been witnessed or recorded in Ireland”.

In addition, it is not confirmed whether the seal in the video is from an Irish resident population or one that travelled here from the North Sea area.

Whooley also posits: “What are the likely implications at population level for the resident harbour porpoises of Clogherhead and beyond? Especially given that areas like north Co Dublin have some of the highest densities of porpoises in Irish waters.”

A humpback whale regularly spotted in Ireland’s South West has been traced to Norwegian waters in the first confirmed link between our two countries, according to the Irish Whale and Dolphin Group (IWDG).

Researchers and citizen scientists in the Happywhale collective made the discovery last week as they matched images of #HBIRL43 — first recorded in Ireland in 2015 — with a whale sighted in the waters of the High Arctic in the vicinity of the Svalbard arcipelago.

“This is our first international re-sighting of this individual who was the first humpback recorded this season off the Stag Rocks in West Cork,” IWDG sightings officer Pádraig Whooley says.

“We documented it this spring/summer on four occasions between 27 April and 6 June. This match suggests it travelled a minimum distance of 3,800km over a period of 75 days, a daily average of 50km.

“This sighting puts it circa 900km further north of the last known position of #HBIRL07 and is our only humpback to be recorded in what we’d term the High Arctic.”

It wasn’t the only remarkable news this week, as Whooley confirms that another Norwegian whale, #NA09849 — which has been sighted regularly off Tromso and Iceland over the last decade — was photographed this past June some 500km west of the Aran Islands.

“We’ve decided that, as this animal was so far offshore and well outside the Irish EEZ in international waters, for now anyway we’d keep it off the Irish catalogue,” he says.

“But it’s another important link to Norway and who knows just how useful these offshore encounters may prove to be in years to come as IWDG continue to unravel the mystery of this most iconic of our whales.”

The Irish Whale and Dolphin Group (IWDG) says last Sunday 29 August will stand out as “particularly memorable” for sightings of humpback whales, with the marine wildlife giants spotted at four separate locations.

At Slea Head in Co Kerry, Jimmy Flannery of Dingle Sea Safari and Nick Massett located and identified #HBIRL107 just south of Crow Rock.

Shortly afterwards, Eoin Delaney was sea kayaking off Carraroe in Connemara when he happened upon a humpback feeding in among common dolphins.

“While we can’t get a positive ID on this individual, any humpback sighting record from Galway Bay is an important event,” IWDG sightings officer Pádraig Whooley says.

Later on Sunday afternoon, Colin Barnes of Cork Whale Watch was on his second trip of the day when he photographed a third humpback breaching close to the cliffs at Scullane Point. This turned to be a new humpback not previously recorded in any Irish waters, and it has been allocated the ID #HBIRL113.

Slightly further away, a pelagic birding voyage off the Isles of Scilly crossed paths with #HBIRL77, a humpback that’s been documented in Ireland’s West and South West coastal waters every year since it was first recorded in 2016 — most recently off the Blaskets in June.

“These encounters and re-sightings are important, as they help IWDG build a more complete picture that reveals how these humpbacks are using Irish and adjacent waters,” Whooley says.

The sightings officer also appealed for anyone “fortunate enough to have an encounter with this most charismatic of our whales” to get in touch with [email protected] with a photograph of the ventral surface of their tail fluke, which is the most effective way for the IWDG to confirm identity.

A local community in eastern Co Mayo rallied to attempt to save as many as 13 common dolphins that live-stranded near Blacksod on Friday (13 August).

As Mayo IWDG’s Facebook reports, the family group comprising 13 dolphins — mainly mothers and calves with a large male — stranded at Tarmon Beach with the tide dropping.

Sadly three of the dolphins died before they could be helped, but the rest responded to being cooled with buckets of seawater by local volunteers assisting the area’s Irish Whale and Dolphin Group (IWDG) members.

As the tide was still dropping for over an hour, it was quickly decided to move the dolphins 2km by road to the slipway at Blacksod where they could be more easily immersed and cared for.

The local IWDG team used their new wheeled dolphin stretcher to transport the larger marine wildlife to a horse box, while the juveniles were carried in beach towels.

Once carefully released back into the water, all were seen to swim quickly and without obvious distress, and by 9pm the pod had left the area.

“Tarmon and the surrounding beaches on the east side of the Mullet Peninsula are notorious for common dolphins live-stranding due to the topography of the beaches,” Mayo IWDG said.

“The beaches are large flat expanses so during spring tides especially, the water can level can drop uniformly and recede up to 1km in parts. Common dolphins being an offshore dolphin species often get caught out on such difficult-to-navigate shallow terrain.

“When a dolphin live-strands it puts immense pressure on their bodies. They can become very disorientated and have muscle spasms from the stranding event making it difficult to swim, which is why this group were given recovery time at Blacksod before being released.

“Thanks again to everyone who helped out today; it was so humbling to see everyone work together to get this pod back to the sea.”

Elsewhere, the IWDG reports on two separate strandings of Sowerby’s beaked whales in Co Galway. The first was found washed up on Inisbofin at the end of the week while the second was reported yesterday (Saturday 14 August) across the water in Cleggan.

Commenting on the former report, the IWDG said: “Beaked whales are not stranded that frequently but this individual had evidence of rope marks on its body.

“As [they are] an offshore deep-diving species we don’t expect beaked whales to get entangled in fishing gear or interact with offshore activity.

“Maybe these rope marks were not from fishing but some other source. Hard to tell, but without a full post-mortem examination the cause of death will remain speculative.”

The Irish Whale and Dolphin Group (IWDG) is backing Limerick sailor Peter Lawless’ pending solo, non-stop round-the-world voyage on his Rival 41 yacht Waxwing.

While the charity has sponsored the yacht’s passive self-steering equipment, in return Peter — son of the late solo circumnavigator Pat Lawless — will be testing out the IWDG’s new reporting app for marine wildlife sightings.

As previously reported on Afloat.ie, sightings and strandings can be reported on the new app by scientists, researchers, boat operators, wildlife enthusiasts and whale-watchers alike.

And Peter — who sets off from Kilrush on 21 August — aims to take the app into the unknown, potentially recoding sightings and even video updated from parts of the ocean that may have never been visited before.

The IWDG’s chief Simon Berrow recently caught up with Peter on Waxwing as he makes his final preparations for his remarkable unassisted voyage:

A recent rare sighting of a blue whale off the west of Ireland is the first in six years, it’s been reported.

Last weekend the Irish Whale and Dolphin Group (IWDG) shared an image of what’s believed to be a blue whale surfacing, as captured by Declan Horan from the the RV Celtic Explorer some 320km west of Slyne Head.

“Although we know from acoustic monitoring during the ObSERVE acoustic project that blue whales occur regularly along the western seaboard during autumn and winter, they are very rarely observed,” the IWDG said.

The Irish Mirror reports that this is the first confirmed sighting of a blue whale in Irish waters in six years — and only the 18th recorded since 2008.

The remains of a whale washed up on a Co Wexford beach are likely to be those of a minke whale, the Irish Whale and Dolphin Group (IWDG) says.

According to The Irish Times, the dead whale was discovered on Blackhall Strand in southwest Wexford yesterday morning, Sunday 13 June.

Going by its description, IWDG sightings officer Pádraig Whooley said it was most likely a minke whale. Wexford County Council said it was appraising the situation, and The Irish Times has more on the story HERE.

Meanwhile, the IWDG has just published a new guide on what to do when encountering a live-stranded whale, dolphin or porpoise.

Along with details on how to assess and care for the animal, Face to Face with a Beached Whale also includes practical information on dealing with other marine wildlife including turtles, seals, otters and seabirds.

The Irish Whale and Dolphin Group (IWDG) says it has confirmed its first humpback whale match between Ireland’s waters and the Canary Islands.

Images of a fluke and dorsal fin captured by Alex Brenner at Valle Gran Rey on La Gomera were, with the help of Nick Massett, compared with those of a humpback photographed by IWDG member Simon Duggan at Baltimore in early December 2012.

“On matching the images we can confirm that this is indeed the same individual #HBIRL21, whom we’ve not recorded in Irish waters over the interim nine years,” the IWDG says.

The development marks an important new connection between Ireland and the Spanish island chain off north-west Africa, following earlier links confirmed with key humpback whale breeding grounds off Cape Verde further south.

A new marine mammal reporting “app” promises to “elevate” recording of whales, dolphins and porpoises in these waters.

Sightings and strandings can be reported on the new “app” by scientists, researchers, boat operators, wildlife enthusiasts and whale watchers, the Irish Whale and Dolphin Group says.

The technology can take the observer logically through the steps necessary for the reporting of both sightings (casual and effort) and strandings (live and dead), the NGO says.

Earlier this week, it was confirmed that over 2,000 people had signed an online petition calling for legal protection for basking sharks in these waters.

The petition was aimed at encouraging TDs to support The Wildlife (Amendment) Bill 2021 tabled last week by Social Democrats TD Jennifer Whitmore.

The bill may make it illegal for anyone to intentionally or recklessly injure, disturb or harass the second-largest fish in the world’s oceans.

Basking sharks are an endangered species, but don’t enjoy the same protection in law as whales, dolphins, porpoise and seals in Irish waters.

IWDG co-ordinator Dr Simon Berrow says: Ireland and its coastal communities have “historically benefited from basking shark fisheries and today we have a duty to provide protection for this highly mobile species when they occupy Irish territorial waters."

The new biological recording tool for cetaceans is being rolled out to coincide with National Biodiversity week.

The IWDG Reporting App has been developed by Compass Informatics and funded by LEADER through the Clare Local Development Company (CLDC).

It will be available to download from today on the App store for iPhones, and the Google Play store for Android.

The Reporting App also links to the iwdg.ie website which offers “seamless browsing of the IWDG’s sightings and stranding datasets with online mapping”.
