A high-protein diet improves birds' ability to tolerate infection, study finds

Whether you feed bread to ducks at the local pond or hang a bird feeder on your back porch, the food you're offering wild birds plays a role in their ability to tolerate infection. New research from the University of Arkansas has found that canaries fed a high-protein diet fared better when it came to immune function and tolerating infection than canaries fed a high-lipid (fatty) diet.
