A recent snowstorm has covered plants and limited the natural food sources available to hummingbirds [1].

This loss of forage creates a critical survival risk for the birds, as they rely on high-energy nectar to maintain their metabolism during cold weather. Without access to their primary food sources, hummingbirds may struggle to find the calories necessary to survive the freeze.

Ornithologist Peter Gent said that the snow covering plants reduces the availability of nectar and insects that hummingbirds normally feed on [1, 2]. Because these birds have such high metabolic rates, any disruption in their food supply can lead to rapid energy depletion.

Gent said people can help the birds by providing supplemental feeding [1, 2]. This intervention provides a reliable energy source when natural flowers are buried under snow or frozen.

Hummingbirds typically forage for small insects and nectar from blooming flowers to sustain themselves. When a snowstorm occurs, these plants become inaccessible, and insect activity drops significantly [1, 2]. Providing feeders allows the birds to bypass the snow-covered vegetation and find the nutrients they need to stay warm.

Experts suggest that maintaining these feeders during unexpected weather events can prevent local population declines. The availability of artificial nectar serves as a bridge until the snow melts and natural foraging becomes possible again [1, 2].

“Snow covering plants reduces the availability of nectar and insects.”

The reliance on supplemental feeding during extreme weather highlights the vulnerability of small avian species to sudden climatic shifts. As unpredictable weather patterns increase, human-provided food sources may become essential for the survival of urban and suburban hummingbird populations.
