Guam kingfishers measure up to nine inches long. Both sexes have a long, stout, pointed bill; a black eye strip; and greenish-blue wings. Males have a cinnamon-colored head and chest, and females have a white chest and belly. Males and females work together to build their nest, an activity that helps with bonding. In the wild, their diet primarily consists of insects and lizards. In zoos, they also eat mice, anoles, crickets, and worms.
