This paper summarises the variations in breeding periodicity in the Australasian - South Pacific region, including recent evidence contrary to previous knowledge. Birds shown to breed in the Samoan islands throughout the year are white-tailed tropicbird (Phäethon lepturus), white-rumped swiftlet (Aerodramus spodiopygius), buff-banded rail (Gallirallus philippensis), brown noddy (Anous stolidus), white tern (Gygis alba) and wattled honeyeater (Foulchaio carunculata). In addition, crimson-crowned fruit-dove (Ptilinopus porphyraceus), blue noddy (Procelsterna caerulea), cardinal honeyeater (Myzomela cardinalis) and Polynesian triller (Lalage maculosa) breed in at least 9 months of the year. The Samoan whistler (Pachycephala flavifrons) has been found breeding in 8 months and the Samoan starling (Aplornis atrifusca) in 7 months of the year.
