On Monday, the first day of our snow this week, I saw this Anna’s hummingbird perched on a branch.
Neighbors and friends feed hummingbirds year round and worry if the feeders freeze. In addition to feeding on nectar hummingbirds can also glean insects from shrubbery. In short periods of cold weather they can lower their body temperature at night by entering into a state of torpor, a form of deep sleep. This can reduce their metabolic rate by up to 95% and consequently use up to 50% less energy.
Hummingbirds are fascinating little critters. Click here for more information about how they survive.
Amazing! I never realized hummingbirds had the ability to survive winter climate.
That is so interesting. I never even thought about how hummingbirds made it through the winter. It reminded me of the arctic squirrel and how they survive the harsh winters. They burrow for the winter (Aug-April) and can lower their body temps almost 70 degrees. All of these little creatures are so amazing. The little bird looks like he relaxing. Nice photo, Kay.
I’m not sure I’ve ever seen a hummingbird sitting still. They’re usually busy flitting! So nice that you and others work to help them survive the winter cold. I wonder if we have them here?
You can get a great winter feeder at http://www.hummersheateddelight.com !
We feed them too. Thanks for the interesting info!
They’re fascinating birds to watch. Terrific shot!
I know some retirees who use that torpor technique, too. Not me.
