Census of seabird colonies on Nordaustlandet, Svalbard, and in neighbouring localities in 1978 and 1979

Seabird colonies were censused during the summer expedition of Norsk Polarinstitutt to Nordaustlandet, Svalbard, in 1978 and 1979, and to Kongsøya in 1979. An outline is given of the distribution of the species together with an estimate of the number of breeding pairs in the colonies. Twentv-five colonies were censused; seven were visited both years. Four colonies with more than 1,000 breeding pairs of the most abundant species, Briinnich's guillemot and kittiwake, were found on Nordaustlandet.
