The marine distribution of seabirds from Christmas Island, Indian Ocean

The distributions at sea of the eight seabird species that breed on Christm as Island were documented during four surveys in the eastern Indian Ocean. Common Noddies and Brown Boobies were seen only within 200-250 km of the is land, whereas Red-footed Boobies occurred up to 800-900 km away. The endemi c Abbott's Boobies probably feed over the South Java Current. The two speci es of frigatebirds were recorded over 700 km from Christmas Island, one spe cies possibly much farther, and the two species of tropicbirds up to 1500 k m from the island.
