The Bumblebee Hummingbird occurs in Mexico. An early naturalist account says males used forest as their main setting but also visited wildflowers.
The nineteenth-century account describes the male with a golden-green back and a glossy red-violet throat ornament. It describes the female throat as white with brown spots.
An early collector reported that males were active early in the morning and used forest while also visiting wildflowers. This is an old observation by one collector.
An extinction-risk assessment has not been added yet.
