Range Description

Megapodius laperouse occurs on Palau and the Northern Mariana Islands (to USA), and is extirpated from Guam (to USA). In Palau, race senex is generally uncommon to rare and locally distributed (VanderWerf 2007), although 'hundreds' were recently reported on Kayangel Atoll (J. Millet in litt. 2007, G. Wiles in litt. 2012). In 1991, the population was estimated at 497 birds, excluding Kayangel (Engbring and Pratt 1985, Engbring 1992). In 2005, a repeat survey found stable numbers on Peleliu and Babeldaob, but evidence of declines in the Rock Islands and on Anguar (VanderWerf 2007). Kayangel Atoll was not included in this survey. In the Marianas, nominate laperouse is mainly restricted to the islands north of Saipan (including Farallon de Medinilla [Lusk et al. 2000]). In 1997, the population was estimated at 1,440-1,975 birds (the largest subpopulation being 545-810 on Sarigan) (USFWS 1998). A remnant population of a few birds may persist on Tinian (Wiles et al. 1987, USFWS 1998, J. Lepson in litt. 1999), although no individuals were detected during a survey in 2008 (Camp et al. 2009). Aguiguan supports a small population (USFWS 1998), and equal numbers of birds were detected during surveys in 1982 and 2008 (14 and 15 birds, respectively [Camp et al. 2009]). A small population (14 birds) was reintroduced on Saipan (Craig 1996); however, during a survey of bird species on Saipan in 2007, the species was not reported (R. Camp in litt. 2008). A significant population on Anatahan, estimated at 200-300 birds (USFWS 1998) was lost in the early 2000s when all habitat on the island was destroyed by a major volcanic eruption.
