Guam Micronesian kingfisher

Latin Name
Todiramphus cinnamominus




The Guam Micronesian kingfisher is a sexually dimorphic species, meaning males and females differ in appearance. Both sexes have a greenish-blue back and wings, but the male has a rich cinnamon head and chest, while the female has a paler head and white chest.



The Guam Micronesian kingfisher was once widespread on the island of Guam but is extinct in the wild due to the introduction of the brown tree snake. Only 100 individuals remain in zoos, which have developed breeding programs to increase their numbers.


Extinct in the wild. Lincoln Park Zoo participates in the Micronesian Kingfisher Species Survival Plan®, a shared conservation effort by zoos throughout the Association of Zoos and Aquariums.


Woodlands and forests


The Guam Micronesian kingfisher feeds on insects and lizards, catching them with its large beak.

Life History

The Guam Micronesian kingfisher's beak is also used to drill holes into trees and rotting wood for nesting. Male and female birds work together to excavate the nest, an activity that may help the pair bond.
