Taxonomic note
Momotus momota, M. coeruliceps, M. lessonii, M. subrufescens, M. bahamensis and M. aequatorialis (del Hoyo and Collar 2014) were previously lumped as M. momota following SACC (2005).

Population justification:

The global population is estimated to number 500,000-4,999,999 mature individuals (Partners in Flight 2019).

Trend justification:

The species is undergoing a small decline (Partners in Flight 2019). Even though it is tolerant of habitat modification, the decline is thought to be caused by ongoing habitat destruction and fragmentation.
