Hummingbirds are small, active birds that rely on their high metabolism to stay warm. When the temperature drops, hummingbirds need to find ways to conserve energy and stay warm. A hummingbird’s body temperature ranges from 102-105 degrees Fahrenheit, and below 50 degrees Fahrenheit, they can enter a state of torpor to conserve energy. During torpor, a hummingbird’s heart rate and breathing slow down, and their body temperature can drop to as low as 40 degrees Fahrenheit.
Hummingbirds are most active in warm weather, and they typically migrate to warmer climates during the winter. However, some hummingbirds will stay in colder climates if they can find enough food and shelter. Hummingbirds that stay in cold climates need to find ways to stay warm, such as roosting in sheltered areas and eating high-energy foods.
If you see a hummingbird in cold weather, you can help it by providing a source of food, such as a sugar water feeder. You can also provide a sheltered place for the hummingbird to roost, such as a birdhouse or a small shelter made of leaves and twigs.
