Range DescriptionRamphiculus merrilli is endemic to Luzon and to two of its satellites, Polillo and Catanduanes, Philippines, where it occurs as two races, faustinoi north of Quiriñon and nominate merrilli south of Quiriñon (Collar et al. 1999). Despite being considered rare, nomadic and under pressure from hunting, the total number of localities for the species is at least 24 and it appears to be fairly common, even in ultrabasic forest, and in 1996 it was found to be abundant on Patnanungan island in the Polillo group. It may prove to be substantially overlooked.
