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.
