Summary:The breeding success of kittiwakes Rissa tridactyla, guillemots Uria aalge. razorbills Alca torda. fulmars Fulmarus glacialis, great skuas Catharacta skua and Arctic skuas Stercorarius parasiticus was monitored on Handa Island during the 1989 and 1990 breeding seasons. In 1989 kittiwakes fledged 1.53 young per well built nest and 1.35 young in 1990. Guillemots had a breeding success rate of 0.69 young fledged per occupied site in 1989 and 0.62 young in 1990. Razorbills fledged 0.73 young per occupied site in 1989 and 0.65 young in 1990. There were 0.62 large fulmar chicks per total pairs monitored in 1989 and 0.61 large chicks in 1990. Great skuas produced a mean of 0.68 young per egg in 1989 and 0.64 young in 1990, and Arctic skuas produced 0.66 young and 0.61 young in 1989 and 1990 respectively.
