Todiramphus albicilla
The Mariana Kingfisher, *Todiramphus albicilla*, is a striking member of the Alcedinidae family, endemic to the Northern Mariana Islands.

Primarily inhabits dense limestone forests, mature secondary growth, and mixed woodland environments, occasionally venturing into coconut plantations and mangroves. Found at low to mid-elevations across its island range.
Feeds predominantly on large terrestrial insects such as grasshoppers, cicadas, beetles, and praying mantises, supplemented by spiders, small lizards, and occasionally small crabs. Foraging is primarily accomplished through perch-to-ground or perch-to-foliage dives.

Historically, it also occurred on Guam, but local populations there were driven to extinction (extirpated) by the accidental introduction of th...
