Resting Anna’s Hummingbird


Resting Anna’s Hummingbird

Hummingbirds have a metabolic range beyond that of most animals.  On the high end, in order to hover and fly forward quickly they flap their wings between 12 to 80 beats per second.  Some species have been clocked at 49 mph.  Heart rates can reach as high as 1260 beats per minute.

On the lower end, hummingbirds can conserve energy nightly and when food is scarce.  They actually goi into a state of torpor, similar to hibernation, and their metabolic rate drops to 1/15th its normal rate.

Flower nectar fuels this metabolic miracle.  If  you don’t have a flower bed, consider putting out hummingbird feeders sweetened at the rate of  1/4 cup sugar to 1 cup water.
