Whooper Swans at Tullagher Bog.
John N Murphy, 5 Ballycasey Grove, Shannon, County Clare.
A shift in wind direction about 8th of the month to strong gale and storm-forced north and south Westerlies produced excellent conditions for a trip to the Bridges of Ross in search of wrecked seabirds. Little Auks were always on the cards and did turn up in small numbers, but no one expected a Pied-billed Grebe on the Loop Head peninsula. After a sea watch at the Bridges of Ross on 11th December a search of the headland and Kilbaha were inevitable. At Cloghaun Lough just east of Kilbaha a Pied-billed Grebe was found feeding within a flock of Teal. This was again a first county record and remained to 13th giving good views during its brief stay. This was for many county birders the icing on the cake to what was overall a memorable ornithological year.

The south and eastern shores are low lying cobbled bolder and sandy beaches at Coonnaluinga, Port Tobacco Cove and Coonabaud. Along this shoreline, the cliffs rise to a height of 15 to 20 feet. A small ruined house and church on this height overlook Port Tobacco Cove facing east towards Lurga Point. Craggaun Rock lies just off the island to the Northeast and Mattle Island 2km to the south. High cliffs to the western side rise to nearly 100 feet between Carricklea and Gorraun Rock. The sea has eroded a puffing hole near Coosnadread and another spectacular one called Taylor’s Hole north of the watch house (old telegraph tower) at Iffinbeg. The centre of the island rises to a hill of about 150 to 200 feet above sea level with gentle slopes, descending east and westwards. The only other high ground on the island is an area north east of Goolar Bay, which slopes gently southwards.

During visits since the early 1990’s, the main priority has been to monitor and count the breeding colonies of gulls. Four species in all breed on Mutton, these being Common, Herring, Lesser Black-backed and Great Black-backed (see distribution map on the following page). There were once small colonies of Terns recorded during the 1970’s and Cormorants also bred. But now both these species have deserted with Cormorants breeding on nearby Mattle Island to the south and no sign of any terns breeding in the surrounding area. Another seabird species, which did breed up to recent times, were Storm Petrels. Searches in early summers of 1990, ‘93 and 1995 were fruitless. Even with the aid of tape lured singing petrels and two night-time efforts to catch and ring, no birds were found or believed to be breeding. Shags and Fulmars frequent and loaf on the cliffs to the western end of the island. Both probably do breed though nesting was not observed. Caves on this western side also play host to breeding Black Guillemots with seven pairs recorded in 1990. Since this count there have only been on average of two pairs per annum during recent visits.
Mutton is of huge importance to a flock of 200 – 300 Barnacle Geese, making the island a nationally important site for this species. Occasionally figures reach high enough for international status of importance. This is also the most southerly feeding site in Ireland for such large numbers of this species. There is only one other site further south in this country that gets a tiny number annually. This is the Wexford Wildfowl Reserve. Mutton’s birds arrive in October and depart for breeding grounds in Greenland during late March early April. It is also of importance for Purple Sandpipers, which feed on Lurga Point and the beach at Seafield. This species traverse between the mainland and island during tidal cycles.

The brown rat Rattus norvegicus probably first appeared on Mutton island during the 16th Century after the Spanish Armada fleets were wrecked near Mal Rock and other rocky shelves of this coastline. Rats might have also reached the island from the mainland by swimming or walking during times of extremely low tides. Locals informed me that it is possible to walk a sand bank to the island in such conditions. For as long as anyone can remember, brown rats were always present on the island and it was only after I visited in May of 1990, that I realise the extraordinary large numbers present. On this overnight stay while surveying the island under spotlights for breeding seabirds, large concentrations of rats were observed pouring out of holes and crevices throughout. These vermin must have a huge detrimental effect on breeding bird populations, and would possibly do most damage to burrow nesting species like Storm Petrels or Manx Shearwaters, if they were present. Worldwide studies have shown that rats predate nests in many isolated islands as food source eating eggs and young as well as adults in some cases. My personal belief is that brown rats are one of the main causes for falling breeding gull numbers on Mutton Island. I also believe that they are the main reason for the desertion of Storm Petrels to nearby Mattle Island. On Mutton rats live a relatively undisturbed life with few predators to effect populations. The presence of Ravens, the odd passing raptor, or visiting humans is the only treats affecting their lives. I believe that rats have an all year round food supply, eating vegetation, seeds, plant roots, seaweed and any small invertebrate found on the shoreline. They must also eat eggs and birds especially sick or injured individuals. I have seen on the island remains of dead goats, hares and rabbits stripped of their flesh by rats. Occasionally dead mammals such as seals and dolphins get washed ashore. These carcasses would keep rats fed for weeks, eating their hosts from the inside out. Other food sources include mammal and Barnacle Geese droppings, all of which graze the island in winter. Both eat tons of grass, leaving behind thousands of nutrient enriched droppings giving a wealth of food supplies for rats.
