DANGEROUS MICROBES LIVING IN HUMMINGBIRD FEEDERS

       We are all concerned about the health of the hummingbirds that we host at our hummingbird feeders.  Consequently we try to keep our feeders as clean as possible in hopes that microbes living on our feeders and the nectar we offer are not going to cause a health problem for our hummingbird neighbors.  For the first time, researchers have focused on what microscopic critters dwell in backyard feeders.

       Scientists at the University of California, Davis, conducted the research.  The research team carried out their study in a backyard located in Winter, California.  Both Anna’s and black-chinned hummingbirds frequented the feeders in this yard.

       During the study, the microbe communities living in the sugar water offered in feeders, on nearby flowers producing nectar, as well as on the hummingbirds themselves were compared.

       The results of the research project indicated that the majority of the bacteria growing in the hummingbird food offered in feeders did not pose a significant health threat to hummingbirds or humans.  However, also present were much smaller populations of bacteria and fungi that could potentially have a harmful effect on humans and hummers.

       It should be noted the scientists found deionized water harbored the most fungi.  In comparison, bacteria were most abundant in tap and bottled water.

       The research team recommended that cleaning hummingbird feeders away from locations where food is prepared.  This would minimize the risk of a potentially harmful pathogen would be spread to humans.

       I think it is abundantly clear we should make every effort to keep our hummingbird feeders as clean as possible.

  1. Thank you for this great insight. I’ll be more diligent than I have been. Cleaning away from food preparation areas and tools makes alot of sense. Thanks again, and I appreciate your blog.
