Cold Snaps – A Risk for Hummingbirds

Hummingbirds need to eat A LOT, almost constantly. It may surprise you that such a small species who weighs about the size of a loonie has a high demand for food sources. Hummingbirds can consume half their weight in pure sugar every day. Nectar fuels hummingbird’s metabolism – the highest of an endothermic animal on the earth. Although these food sources are readily available in the spring and summer, winter becomes challenging. Insects and nectar-bearing flowering plants are scarce during freezing temperatures.
