ARENTAL BEHAVIOUR BY TWO PAIRS OF GUAM MICRONESIAN KINGFISHERS Halcyon cinnamomina cinnamomina

摘要

Historically, the Guam Micronesian Kingfisher Halcyon c. cinnamomina - hereafter referred to as the Micronesian Kingfisher - existed throughout the forested regions of Guam (Fry et al. 1992). The population of this subspecies was decimated following the unintentional introduction of the Brown Tree Snake Boiga irregularis to the island and by 1986 the Micronesian Kingfisher was extinct in the wild (Savidge, 1987; Wiles et al. 2003). Today, the Micronesian Kingfisher survives only in captivity as partof a captive propagation programme. The birds are spread among 11 institutions in the USA and one on Guam (Banner, 2006). The goal of the propagation programme is to increase the population through captive breeding for release in the future on Guam or other appropriate sites (U.S. Fish and Wildlife Service, 2004).
