The Guam kingfisher (''Todiramphus cinnamominus'') is a species of kingfisher from the Pacific Islands of Guam. It is restricted to a captive breeding program following its extinction in the wild due to the introduced brown tree snake. ==Taxonomy and description==
In addition, the mysterious extinct Ryūkyū kingfisher, known from a single specimen, is sometimes placed as a subspecies (''T. c. miyakoensis''; Fry ''et al.''. 1992). Among-island differences in morphological, behavioral, and ecological characteristics have been determined sufficient that Micronesian kingfisher populations, of which the Guam kingfisher was considered a subspecies, should be split into separate species. This is a brilliantly colored, medium-sized kingfisher, 20–24 cm in length. They have iridescent blue backs and rusty-cinnamon heads. Adult male Guam kingfishers have cinnamon underparts while females and juveniles are white below. They have large laterally-flattened bills and dark legs. The calls of Micronesian kingfishers are generally raspy chattering.
