HUMMINGBIRDS

How long do hummingbirds live?

There's not a lot of data to work with, but most experts think the average lifespan of a hummer is 3 or 4 years. The record was a female Broad-tailed, banded as an adult in Colorado in 1976, then recaptured in the same location in 1987, which would have made her at least 12 years old.

How fast do hummingbird hearts beat?

A rate of 1260 beats per minute was measured in a Blue-throated Hummingbird. In torpid hummingbirds, the heart rate can drop to 50-180 per minute.
