How Climate Change Impacts Birds, Their Feeding Habits and How to Help from Home

(Joan Casanova) Bird feeding is a common practice in the United States, with more than 59 million Americans participating, according to the U.S. Fish & Wildlife Service. In addition to providing aesthetic and recreational benefits, bird feeding can have positive impacts on bird populations.

According to the National Audubon Society, birds provide important ecosystem services, such as pollination, pest control and seed dispersal. In fact, around 87% of flowering plants rely on animal pollinators, including birds, to reproduce and grow, according to a study published in “Science.” Birds also consume fruits and berries then spread the seeds, which helps maintain biodiversity and promotes the growth of new plants.

Considered good indicators of the health of the ecosystem, changes in bird populations and behaviors can signal changes in the environment, such as pollution, habitat loss and climate change. As temperatures, weather patterns and ecosystems change, it can affect the availability of food for birds, which may alter their behavior.
