*Archilochus colubris*

To save energy on cold nights, they can enter torpor—a deep sleep where their heart rate drops from 1,200 to only 50 beats per minute.

## About

The ruby-throated hummingbird ( Archilochus colubris ) is a species of hummingbird that generally spends the winter in Central America, Mexico, and Florida, and migrates to Canada and other parts of Eastern North America for the summer to breed. It is by far the most common hummingbird seen east of the Mississippi River in North America.
