Monitoring Haul Round is small and flat, suitable for monitoring by cameras with independent power and sufficient protection from weather and human interference. We recommend installation of digital video cameras linked to suitable hard drive and solar power. Used in conjunction with on-site estimates of bird numbers this can give a reasonable and repeatable estimate of the proportion of eggs harvested. These could be set up at the beginning of each breeding season and then removed at the end of each season. Maine Island. Maine Island is a small island (1 hectare) consisting of a very small sand spit and surrounding rocky area. Only the sand is exposed at high tide. It is 5 km from the mainland and 50 km north east of Maningrida. Five species of colonial-nesting seabirds were recorded in July 2009. Around 80 crested tern, 60 roseate tern, 20 black-naped tern, 10 lesser crested tern and 7 little tern were present. Also present were approximately 300 lesser sand plover. There was no evidence of breeding for any species; however Dion Cooper stated the sandy portion of the island is used for nesting by large-egged tern species, probably crested tern.
