Microbes Grow in Hummingbird Feeders But Do Not Likely Pose Health Hazard
Many people set up hummingbird feeders in their yards to nurture and watch these high-energy pollinators. But could the sugar water they provide be impacting these tiny feathered friends?
A study led by the University of California, Davis, is one of the first to address the potential for sugar water from hummingbird feeders to act as a vector for avian — or even zoonotic — pathogens. It found that the majority of microbes growing in feeders do not likely pose a significant health hazard to birds or humans.
