Site description (baseline)
Farallon de Pajaros is the northernmost island in the CNMI. The island is a steep volcanic cone, which has erupted several times in the last century. The island is largely bare exposed rock with little vegetation. The proposed IBA is uninhabited and protected by CNMI law as a Wildlife Conservation Area.

Key biodiversity
The entire island of Uracus is proposed as an IBA because of its population of breeding seabirds. Uracus qualifies under both A4i criteria for its population of Sooty Terns and under A4iii for its total population. Micronesian Megapodes are also breeding on the island (Reichel and Glass, 1991).
