The Irish Whale and Dolphin Group has conformed the first validated sighting of a fin whale off Co Donegal.
Liz Morrow captured images of the solo large whale in Donegal Bay off Slieve League earlier this month, estimating it to be around 18 metres in length.
Fin whales are a common occurrence in Ireland’s South West and the Celtic Sea, but have never before been spotted in the inshore waters of the colder North West.
However, with the later sighting of a humpback whale breaching off Malin Beg, it could be a sign that larger marine wildlife are exploring new territory north of Sligo.
“Any large whales that simply look too large to be a minke or humpback and produce a powerful columnar ‘blow’ on surfacing, should be considered as likely candidates,” the IWDG suggests.
“They will often be accompanied by common dolphins who hunt the same sprat and herring shoals and they never lift their tails before diving.”
Suspected fin whales are best approached from the right side and photographed at the head and rostrum “which should reveal the diagnostic lower white right jaw”.
Though photo opportunities may be tempting, the public has been urged to stay away from the carcass for health and safety reasons.
Fin whales are sometimes spotted offshore, says Dave Wall of the Irish Whale and Dolphin Group (IWDG), who added that this whale was likely dead for some time before its carcass beached.
It’s not known what causes the fin whale’s death. But marine debris — especially microbeads from bathroom products – is a growing threat to all whales, dolphins and porpoise in Irish waters, as the IWDG recently reported.
Citing a new study that found marine debris (such as plastic bags and fish hooks) in the digestive tracts of 8.5% of cetaceans examined, the IWDG highlights that micro-plastics were present in the guts of every animal in the study.
“While larger marine debris has been shown to cause impaction of the gut and other complications which can lead to death, the impact of micro-plastic contamination is not known,” says the group.
“It is thought it can act as a vehicle for persistent pollutants, which adhere to the large surface area resulting in a potential increase in contaminant burdens in marine mammals.”

“You never get them in the North Sea, so what it was doing there, we have no idea at the moment,” biologist Dr Ben Garrod told the newspaper.
#MarineWildlife - Whale sightings are on the increase in the South East this week as the season tapers off, according to the Irish Whale and Dolphin Group (IWDG).
"As large whales don't keep to our calendar year, this annual south east flurry of large whale sightings represents the tail-end our our large whale season," says the IWDG's sightings officer Pádraig Whooley.
"And what a season it has been, especially for the humpback whale, which have enjoyed a record year both in terms of frequency of sightings since they first appeared in early May off the Slea Head Peninsula."
The latest spots were made both on land – by Andrew Malcolm and Ann Trimble from Ardmore Co in Waterford at the weekend – and on a whale-watching trip with Martin Colfer's South Coast Charter Angling, recording a humpback whale and more than five fin whales between them.
And there might still be time to head down to the Sunny South East to catch a glimpse of these ocean giants before they depart for the spring.
#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has proposed a restriction of seismic survey activity on the slopes of the Irish continental shelf and the Porcupine Seablight.
The IWDG says its move "stems from an increasing body of evidence which indicates that the Irish Shelf Slopes and Porcupine Seablight are an important migration route and opportunistic foraging area for blue whales and fin whales from August to March each year.
"Humpback whales are also known to migrate along a similar route in the winter and early spring," it added in a statement.
The cetacean conservation charity as expressed concern at what it perceives as "a large increase in seismic survey activity in the Porpcupine Seablight during the main migration period and recent evidence of disturbance to these migrating whales by seismic surveys."
As a result, the IWDG has proposed to the Petroleum Affairs Division of the Department of Natural Resources that seismic surveys – such as that scheduled to be conducted in the Porcupine Basin this September – be "restricted to the months March to August, outside of the migration period, in order to minimise disturbance to these highly endangered whale species."
According to the group "similar measures" have been successful in other parts of the world, such as off South Africa, where whales "seasonally occur in large numbers".

#MarineWildlife - Late summer brings fin whales flocking to West Cork in big numbers, with the Irish Whale and Dolphin Group estimating at least 20 of the second-largest ocean species sighted between Seven Heads and Galley Head.
Indeed, as IWDG sightings officer Padraig Whooley writes, the gathering "is certainly the largest validated aggregation of this species so far this year" and comes some months ahead of the usual peak from October to December.
Recommended spots for watching these fin whale visitors - though you will need some decent binoculars to get the best views - are the aforementioned Galley Head and Seven Heads as eel as Cloghna Head, Dunworley and Sandscove.
Kerry has its own share of whale visitors, with a "lovely run" of humpbacks in recent weeks, while East Coast residents aren't left out, either, with a rare sighting of a minke whale in the Irish Sea some 20km off Bray Head over a week ago.
In other cetacean news, West Cork has become home to a new solitary dolphin in the form of Clet, a bottlenose who's been spotted in Glandore, Baltimore and Schull after time from Devon, Cornwall, South Wales and originally France.
Yet as IWDG welfare officer Paul Kiernan warns, Clet might appear cute but he's very much a wild animal, with reports claiming a swimmer off Sherkin Island was "aggressively pushed underwater by the dolphin".
Such stories, Kiernan writes, point "to the need for people to exercise common sense and extreme caution in how best to enjoy an interaction with this very large, apex predator."
He adds: "Bottlenose dolphins are not cute and cuddly, they are not our 'friends' and nor do they benefit in any meaningful or long term way from interacting with humans."
#MarineWildlife - The Irish Whale and Dolphin Group is reporting a "high volume of sightings" of minke whales - plus the odd fin whale - off the coasts of West Cork and Kerry as this week's heatwave continues to bask the country.
The first reports from the early part of the week showed a big increase of sightings and activity in the southwest region - but also off Mullaghmore, the popular surfing spot in Co Sligo, where as many as three minkes were spotted last weekend, and as far afield as Belfast Lough where several minke whales were photographed.
As the week progressed, the first confirmed sighting of a fin whale came in from Slea Head in Co Kerry in waters teeming with six minke whales and around 150 common dolphins.
And a whale watch trip of West Cork came into range of an amazing 12 minke whales, including a number of juveniles who seemed to make a game of swimming around the watchers' vessel.
The latest reports came in on Thursday from Baltimore and Clougher Head, which indicate that fin whales may be arriving here in big numbers. Here's hoping a few humpbacks will follow in their wake!
#MarineWildlife - Here's a little something cheerful to brighten up this chilly, snowy Monday morning: some video footage from YouTube shot by Irish Whale and Dolphin Group (IWDG) member Karl Grabe of the first whales to visit Ireland's shores in 2013.
As previously reported on Afloat.ie, the first sightings were made last week on the maiden member whale-watching trip on board the IWDG's new marine wildlife research vessel Celtic Mist off the coast of Wexford.
In addition to these fin whales, the group also made the acquaintance of a group of frolicking dolphins from the 'superpod' spotted in the Irish Sea recently, as you can see from the clip below:
#MarineWildlife - The whale watching season is well under way off the coast of Wexford, as the Irish Whale and Dolphin Group (IWDG) reported its first sightings of 2013 this week.
Just an hour into the maiden cetacean spotting voyage of the IWDG's new research vessel Celtic Mist at the weekend, members of the group were treated to the sight of fin whales and minke whales feeding south of Hook Head - not to mention some of the 'superpod' of dolphins seen last week in the Irish Sea.
Murray suggested that "a large herring haul going on in the southeast at the moment" is the main attraction for the ocean giants and their smaller, more plentiful companions.
The IWDG's Facebook page has a photo gallery containing some stunning snapshots of the day's excursion HERE.
#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) reports of another "frenzy of activity" while on a whale research cruise off West Cork this week.
The 'members only' trip on Wednesday 5 December took in the hotspot west of Reen Pier in Union Hall "where humpback and fin whales have enthralled hundreds of whale watchers and wildlife enthusiasts alike in recent weeks," according to IWDG sightings co-ordinator Pádraig Whooley.
When it soon became clear that most of the whales had left the area, the team headed east to return an ill member to shore.
"This turn of events proved almost karmic," says Whooley, "as not long after dropping our colleague back to Reen Pier, we started getting text messages from IWDG observers Tim Feen and Chris O'Sullivan of both humpback and fin whales well to the east on the Clonakilty Bay side of Galley Head."
Racing against the fading afternoon light, the boat made it to the scene to witness the blows first of fin whales, then humpbacks - at least five of the latter and seven of the former - and confirming them as the giants previously seen between the Kedge and Stags.
The team collected biopsy samples from most of the relaxed pod, including one that is suspected to be a female humpback with a calf.
"Since then, the weather has been very poor," says Whooley, "but there are still sufficient reports coming into IWDG to suggest to us that the large whale activity is slowly pushing east."
The IWDG is also collaborating with the BBC's WinterWatch programme next week, which is hoping to follow up on last year's AutumnWatch special on fin whales from East Cork and Waterford by filming humpback whales in West Cork.
Members of the public or whale-watchers are encouraged to report any sightings they might witness over the weekend to the IWDG by using the 'Report a sighting' link on the home page at iwdg.ie.
