Whales found dead on Donegal beach

Scientists have taken skin and tissue samples from the 33 pilot whales which died off the coast of County Donegal.


Environmentalists are trying to establish how the whales beached on Rutland Island near Burtonport.

It's thought they were the same group spotted in the Outer Hebrides at the end of October.

Dr Simon Berrow of the Irish Whale and Dolphin Group said it was one of the biggest mass deaths of whales in Irish history.

He is concerned that Royal Navy sonar equipment could have played a role.

"Thirty or 40 pilot whales were spotted off the Outer Hebrides at South Uist last week," he said.

"It looked like they were going to strand. It was bad weather. They were not seen again."

Dr Berrow said the Royal Navy had been in the area off South Uist and had moved away.


Campaigners were concerned that the latest sonar equipment could have disturbed the navigational skills of this deep diving species of whales.

But a spokeswoman from the Royal Navy said that when the whales were spotted near South Uist, the closest navy ship was 50 miles away.

At that distance, she said, there was no way that the sonar equipment could have affected them.

In the past, the navy has denied that sonar noise from their warships could cause whales to beach.


However, in America, the US Navy was ordered not to use mid-frequency sonar during training exercises from 2007 and 2009, after a judge found in favour of campaigners who argued the devices harmed marine mammals in the area.

A team from Galway/Mayo Institute of Technology travelled to the scene off Donegal to take samples from the mammals.

Skin samples will also be sent to the Irish Cetacean Genetic Tissue Bank at the Natural History Museum in Dublin.

Sixty whales died in the 1960s off the west coast of Kerry and 35 to 40 animals died in north Kerry in 2001.

Eimear McGee: "They're a very strong social group... so the sick and the healthy died here together"

Mink release in Donegal threatens birds

Irresponsible mink release in Donegal poses serious threat to wildlife

October 2010. Ireland's largest conservation NGO, BirdWatch Ireland, is seriously concerned by the recent release of 5,000 mink from a fur farm near Ardara in Donegal, indicating that it could have devastating consequences for wildlife in the area and particularly for already rare ground-nesting birds. Western Donegal contains some of the most threatened bird species in all of Ireland, and indeed is the last Irish refuge for the internationally important Red-throated Diver, of which only 4-8 breeding pairs remain. Ground nesting birds are especially vulnerable to mink predation and their potential increase in numbers as a result of this release poses a particularly serious threat.

Puffin, Manx Shearwater and Storm Petrel threatened

For example, current BirdWatch Ireland conservation projects focussed on breeding waders such as Lapwing and Redshank and seabirds such as Puffin, Manx Shearwater and Storm Petrel have identified predation by mink as a considerable threat in some cases. They are also likely to affect many other native birds and other wildlife, including, for example, important Atlantic Salmon populations. The prompt action of the National Association of Regional Game Councils (NARGC) and of angling clubs in the area to catch as many of the escaped mink as possible is commended.

Currently mink densities are highest in the east of Ireland. However this latest release could boost mink numbers in the west and speed up their colonisation. The west of Ireland contains many key sites for nationally and internationally important bird species that are now at real risk from this invasive alien species.

Fur farming
The development of fur farming is the origin of mink in Ireland. American Mink, native to North America, were first recorded in the wild in Ireland during the early 1960's, having been released, accidentally or on purpose, from these fur farms. Peadar O'Connell, Species Policy Officer at BirdWatch Ireland said, "The problem stems from the fact that there are no natural controls, such as predators, food supply or disease, to limit the mink population, allowing it to grow relatively unchecked and filling the niche of a broad spectrum predator able to exploit many food sources and negatively affect native species."

Fur farms to close
Whatever the reasons for the release, allowing a large number of non-native predators into the wild is potentially damaging and should be investigated by the appropriate authorities. The continued existence of fur farming, however, is the root of the problem and the expected closure of such farms in 2012 under the current Programme for Government is long awaited and should help to prevent similar future problems.

Initiatives such as Invasive Species Ireland have worked on identifying methods to tackle the issue of invasive species but there is a lack of a coherent national strategy to deal with incidences such as this release. Alan Lauder, Head of Conservation at BirdWatch Ireland, said, "Incidents like this highlight a fire-fighting approach within Government in relation to invasive species rather than a planned and co-ordinated approach."

Huge cost
Alan Lauder continued, "This may also therefore be a good time to consider the possibility of mink eradication. It has been estimated in a National Parks & Wildlife Service funded project that to remove mink from an 800 km² area would cost roughly €1,062,425 over a five year period. This would need to be scaled up to eradicate mink from the entire country, but considering the funds required to protect our native species, domestic poultry and fish stocks from the threat of predation by American Mink, it would seem a sensible investment. On top of this comes the threat of EU fines if Ireland fails adequately to protect its threatened wildlife, so dealing properly with the problem now makes sound economic sense and represents a substantial long term saving not just for the national exchequer but also for Ireland's unique natural heritage which is important to us all."
