New study offers insight into hummingbirds’ hibernation-like rest | Globalnews.ca

75% Informative
New research is providing insight into when torpor happens in some varieties of hummingbirds common to B.C. The Calliope and rufous hummingbirds require at least 180 milligrams of fat in the morning to get them started toward their next meal, so their bodies automatically enter hibernation mode.
If the hummingbirds can’t find food, being forced into torpor can be risky, and it can also impact their immune system.
“So, there’s been good work in this area, but this really adds to it quite well.” This report by The Canadian Press was first published Feb. 1, 2025 .
