I started looking at the Pacific Gull in 1976. I am interested in their taxonomy, evolution, breeding biology (nests, eggs and chicks; pair bond structure), growth and development of immatures and ecology (post-fledging dispersal, natality, calls and postures, longevity, mortality, movements). In 1978, I started looking at the Kelp Gull in Australia. I am interested in their taxonomy, breeding biology and ecology in Australia, including competition with the Pacific Gull.
