Kittiwakes' trans-Atlantic winter odyssey linked to breeding success
Date:1/4/2011

One of Britain's best known seabirds winters on opposite sides of the Atlantic depending on whether its breeding attempt has been successful according to new research published today in the journal Proceedings of the Royal Society B. The findings highlight previously unsuspected links between summer breeding performance and wintering distributions of kittiwakes.

The research team was led by Dr Maria Bogdanova from the Centre for Ecology & Hydrology (CEH) in conjunction with colleagues from CEH and the British Antarctic Survey (BAS).

The discovery of such patterns of segregated winter distributions is important for defining key wintering areas in declining species such as the kittiwake that are experiencing poor breeding seasons with increasing regularity.

The results show kittiwakes that experienced breeding failure left their colony earlier than successful breeders. Failed breeders then travelled over 3000km and wintered off Canada while their successful neighbours remained close to Britain. The two groups did not differ in the timing of return to the colony the following spring. However, over half the males from both groups made a previously undescribed long-distance journey out into the central Atlantic before the breeding season.

Lead author Dr Maria Bogdanova, an animal population ecologist at the Centre for Ecology & Hydrology, said, "Our results demonstrate important but previously poorly understood links between breeding performance and winter distribution, with significant implications for populations. It is fascinating that successful and unsuccessful pairs nesting only a few metres apart in the colony can be separated by thousands of kilometres in the winter."

This study used a tiny instrument (1.4g) known as a geolocator for tracking animal migration. During the 2007 breeding season, the team fitted 80 kittiwakes on the Isle of May NNR off the east coast of Scotland, with geolocators.
