How bird feeders help small species fight infection
(2023) In The Conversation- Abstract
- Every day, throughout the world, people put huge quantities of food out at feeding stations for birds and other wild animals.
Although we know that connecting with nature benefits human health and wellbeing, scientists still know relatively little about the consequences of providing food for wildlife. My team’s most recent research, however, has found that feeding garden birds in wintertime seems to make them more resilient to infection.
Winter can be tough for small birds. During cold winter nights, small birds reduce their body temperature by several degrees. While this would be lethal for a human, it saves lots of energy, helping birds to survive particularly cold nights. However, reducing body temperature is risky,...

Although we know that connecting with nature benefits human health and wellbeing, scientists still know relatively little about the consequences of providing food for wildlife. My team’s most recent research, however, has found that feeding garden birds in wintertime seems to make them more resilient to infection.
Winter can be tough for small birds. During cold winter nights, small birds reduce their body temperature by several degrees. While this would be lethal for a human, it saves lots of energy, helping birds to survive particularly cold nights. However, reducing body temperature is risky, and hypothermic birds are slow to wake and respond to a predator.
A reliable food supply at bird feeders can help small birds avoid starvation and survive the harsh winter. Our previous research showed that birds with access to feeders do not need to reduce their night-time body temperature as much as birds that did not have access to feeders. The extra energy birds get from human-provided food means they don’t have to take the risk of becoming severely hypothermic. (Less)
