A “breeding colony” for New Zealand seabirds is defined as “any location where breeding has been reported and is considered by the expert compiling the species account to have occurred at that location at least until 1998”. 2. An “occasional breeding colony” for New Zealand seabirds is defined as “any location where breeding has been reported, but not necessarily continuously nor during consecutive breeding seasons, and is considered by the expert compiling the species account to have occurred at that location during the last 30 years”. 3. Literature sources were searched for breeding distribution information. a. Scientific papers, published texts, unpublished reports and university theses available to the expert who prepared the distributional layers. b. Aquatic Sciences and Fisheries Abstracts for 1960-2009. c. OSNZ News and Southern Bird for 1977–2009. 4. Other sources. a. Nil. 5. The mapping of the Brown noddy breeding colony at Curtis Island is based on a written description of its location in Veitch et al. (2004) during 1989, those of the breeding colonies at Lord Howe Island and Norfolk Island are based on written descriptions of their locations in Higgins & Davies (1996), and that of the unknown breeding colony at L’Esperance Rock is based on a written description of its location in Greene et al. (2004) during 2002. The colonies have not been surveyed for mapping purposes, and the mapping presented is based on the written descriptions of their locations. 6. Summary a. An expert scientist integrated information from the literature and expert opinion, and produced hand-drawn distributional zones on a template map. These maps were then digitised and imported into a GIS software package as layers. The areas of the zones were calculated, and the layers were linked to attribute and metadata files. b. The primary sources of breeding distribution data for Brown noddy were papers published in refereed journals. c. The Brown noddy is indigenous to New Zealand and breeds at Curtis Island within the Kermadec Islands, and also at Lord Howe and Norfolk Islands (Australia). This species may also breed at L’Esperance Rock, Kermadec Islands, but this remains to be confirmed as a breeding site. d. In 1989, 25 pairs of Brown noddy were found breeding at Curtis Island within the Kermadec Islands archipelago (Tennyson & Taylor 1990, Veitch et al. 2004). This remains the only confirmed breeding record for New Zealand. More recently, Greene et al. (2004) reported two birds flying off L’Esperance Rock (Kermadec Islands) in July 2002 and speculated that this might be an additional breeding site for the species. Elsewhere in the region, Brown noddy nest at Lord Howe Island, where it is estimated more than 1,000 pairs breed, and at Norfolk Island, where a similar number breed (Higgins & Davies 1996). e. The current population trends are unknown for this species. f. Elsewhere, this subspecies breeds from the Seychelles and Madagascar eastwards to northern Australia, Polynesia, Hawaii and Easter Island (Taylor 2000). 7.
