Hummingbirds in the Rocky Mountains: Species, Altitude, and Gardening

Rocky Mountain scene

In the Rockies, hummingbird season is short, intense, and governed almost entirely by altitude. Birds arrive late, breed fast, and leave early, squeezing an entire nesting cycle into the brief window when high-country meadows are in flower. They do it in a place where the temperature can drop below freezing on a July night.

How Long Do Hummingbirds Live?

Hummingbirds burn energy faster than almost any animal alive; a hummingbird’s lifespan seems like it should be measured in months. Its heart can beat over a thousand times a minute; it must eat every few minutes through the day, and a single cold night without fuel can kill it.
