Seabird ‘cities’ continue to struggle

Reports of seabird breeding performance on a number of RSPB Scotland’s coastal reserves indicate continuing problems for the country’s internationally-important seabird colonies.

In light of the poor breeding performance on these reserves and the mixed picture elsewhere, The RSPB is calling on the UK Governments to ensure that the areas that important for seabirds at sea, particularly where they forage of food, are included and adequately protected in the networks of Marine Protected Areas that are currently being discussed in Scotland, England and Wales.

The biggest population declines were in the northern isles, with reserves in Orkney showing significant drops in populations of sensitive species such as Arctic terns and kittiwakes.

A full colony count at Marwick Head reserve on the Orkney mainland showed a staggering 53% decline in the total number of seabirds present since the last full census of the UK’s seabird populations in 2000 and a 22% decline since the last colony count in 2006.

Guillemots and kittiwakes failed to produce a single chick at Noup Head, while on RSPB’s North Hill reserve, breeding pairs of Arctic skuas were down by nearly half. The single remaining pair of kittiwakes on this reserve failed to raise any young at a colony that once had over 150 pairs of breeding kittiwakes.

On the Western Isles and Inner Hebrides numbers were also low, and breeding attempts were not helped by gale force winds in the last week of May which ruined a high proportion of nesting attempts for terns in particular.

Dr Sharon Thompson is the senior marine policy officer at the RSPB‘s headquarters. Commenting on the need for better protection for seabirds at sea, she said: “Whether populations are in decline or in good health or improving, marine protected areas are an important tool for protecting the areas that are vital for seabirds at sea.

“We have the national and international laws needed to protect our marine wildlife, including seabirds, and the process of selecting these sites and forming a network of marine protected areas is underway. Unfortunately, the needs of some of our most precious sealife are not being considered properly.”

The success or failure of seabird breeding seasons are an indication of the health of the marine environment as a whole and a reminder to the UK Government and devolved administrations of the need to prioritise and carry out a full census of the country’s seabird colonies. The comprehensive survey will allow scientists to accurately monitor long-term trends and target conservation action for important seabird populations.

Doug Gilbert, Head of Reserves Ecology for RSPB Scotland, said: “The terrible season for critical colonies in the far north warns us that seabird populations in the UK remain in real danger. This is against the backdrop of long term decline for many species. Carrying out another full census is vital. By knowing how different species are faring, conservationists can then attempt to determine causes of decline and the means of protecting these species.”
