Haul Round and Maine islands were visited on 8th and 9th July 2009. Objectives were to: trial seabird monitoring methods and the data sheet (see appendix 2 for data sheet); identify and count colonial nesting seabirds present on both islands; on Haul Round to investigate feasibility of installing cameras to monitor quantities of eggs harvested by local people from Maningrida. Six species of colonial-nesting seabirds were recorded. All these were previously recorded by Chatto (2001), apart from black noddy. The most abundant species was bridled tern, with an estimated 400 birds present. Also present were around 140 crested tern; approximately 30 roseate tern, 5 black-naped tern, 5 silver gull and a single black noddy. Identification sheets for these species can be found in the back of this report. Two species were confirmed breeding in 2009 - bridled tern and silver gull. Judging from trampled vegetation, old eggshells and guano deposited, bridled terns had nested over the whole vegetated part of the island. Breeding was nearly finished by July; one intact egg and one fledgling were recorded.
