One of the most spectacular population increases of an Australian seabird has
been that of the Silver Gull Larus novaehollandiae
breeding on the Five Islands off
Port Kembla, N.S.W. From a small and presumably stable breeding population of about
1 000 pairs prior to 1940, it has expanded to over 50 000 breeding pairs in 1978, thus
becoming the most obvious bird of coastal, urban and suburban Wollongong, with
increasing abundance also notable in its metropolitan foraging range.
This paper records some quantitative data on the population growth and suggests
the principal factor responsible.
