Anna’s Hummingbirds in Winter

I am always amazed when I see an Anna’s Hummingbird at my feeder when it is 24 degrees outside. How do they survive in this cold weather in the Pacific Northwest? In cold weather, they will go into  a state of “torpor”, an energy saving mode where their heart rate and body temperature are reduced to a minimum.  They also survive on insects found in trees and crevices, as well as hummingbird feeders. So I will be keeping my feeders out this winter to help these beautiful birds survive.

  1. We are in TX now, and they only have ruby-throated hummers, which is cool, but those rascals migrate by Nov. My CA hummers toughed it out all winter even in the high desert cold!

I'd love to hear from you
