THE IUCN RED LIST OF THREATENED SPECIES™ Taxonomy Kingdom Phylum Class Order Family Animalia Chordata Aves Coraciiformes Alcedinidae Taxon Name: Todiramphus cinnamominus (Swainson, 1821) Common Name(s): • English: Guam Kingfisher, Micronesian Kingfisher Taxonomic Source(s): del Hoyo, J., Collar, N.J., Christie, D.A., Elliott, A. and Fishpool, L.D.C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Volume 1: Non-passerines. Lynx Edicions BirdLife International, Barcelona, Spain and Cambridge, UK. Taxonomic Notes: Todiramphus cinnamominus, T. pelewensis and T. reichenbachii (del Hoyo and Collar 2014) were previously lumped as T. cinnamominus following Sibley and Monroe (1990, 1993). Identification Information: 20 cm. A distinctive small kingfisher with a rich rufous top of the head, underparts and hindcollar, greenish-black mask extending as a thin band around the hindneck and shining blue-green mantle, wings and tail. Bill is black. The female has a white belly, sharply demarcated from the rufous on the breast. Similar species. T. pelewensis and T. reichenbachii have clean white underparts. Assessment Information Red List Category & Criteria: Extinct in the Wild ver 3.1 Year Published: 2017 Date Assessed: October 1, 2016 Justification: This recently-split kingfisher was endemic to the island of Guam, but following predation by invasive snakes it became Extinct in the Wild in 1986 when the last remaining wild birds were taken into captivity for captive breeding.

What were believed to be the last 29 individuals were caught and taken into captivity in 1986; this captive population now numbers 124 individuals spread around various facilities in the U.S.A (D. Kesler in litt. 2013).

Habitat and Ecology (see Appendix for additional information) The species was previously found in a fairly wide variety of habitats throughout the island of Guam, including the edges of mangroves, wooded coastal lowlands, coconut palms and mixed upland forest and also large gardens with plenty of timber (Fry and Fry 1999, del Hoyo et al. 2001, Kesler in litt. 2013). The breeding season was between December and July, with the nest excavated into a rotten tree (Fry and Fry 1999). Systems: Terrestrial Threats (see Appendix for additional information) Its decline and extinction in the wild is the result of predation by the introduced brown tree snake Boiga irregularis (Fritts and Rodda 1998). Predation by feral cats may have represented an additional threat. Conservation Actions (see Appendix for additional information) Conservation and research actions underway In 2013 the captive population numbered 124 individuals spread around various facilities in the U.S.A (D. Kesler in litt. 2013). The captive population is considered to be close to or at capacity for the facilities currently holding birds, and there is a need for an appropriate reintroduction site to be identified (Laws and Kesler 2012, Kesler in litt. 2013), with a bayesian modelling approach being used to identify islands that may be suitable for translocation (Laws and Kesler 2012). Conservation and research actions proposed Continue the captive-breeding programme. Control B. irregularis and feral cats F. catus on Guam so that there is the potential for reintroductions to take place in the future. Identify one or more suitable reintroduction or translocation sites. Credits Assessor(s): BirdLife International Reviewer(s): Butchart, S. & Symes, A.
