Population justification: There are estimated to be hundreds of birds in Kayangel (J. Millet in litt. 2007), 497 birds in the rest of Palau (Engbring and Pratt 1985, Engbring 1992), and 1,440-1,975 birds in the Marianas (USFWS 1998). These estimates total 2,000-2,500 individuals, roughly equating to 1,300-1,700 mature individuals.
Trend justification: The Palau population is suspected to be undergoing a continued decline (VanderWerf 2007) owing to human disturbance of nest mounds and the effects of introduced species and continued persecution; however, the likely rate of decline has not been estimated.
