Feeding birds in winter
Cleaning
“Clean your seed or suet feeders regularly (e.g., every week or two) and more often during periods of heavy use or wet weather.”
Cornell Lab of Ornithology, Project FeederWatch
“Debris (such as leftover bits of seeds and hulls) can harbor pathogens that make birds sick.”
Cornell Lab of Ornithology, Project FeederWatch
Disinfecting
“To disinfect your feeders, soak the (cleaned) parts for 10 minutes in a diluted bleach solution (e.g., one part bleach to nine parts water).”
Cornell Lab of Ornithology, Project FeederWatch
Sick birds
“Fluffed-up feathers, lethargy, abnormal growths, and crusty eyes are all symptoms of various avian illnesses.”
Cornell Lab of Ornithology, Project FeederWatch
House finches
“For example, not every bird that is exposed to Mycoplasma gallisepticum will contract conjunctivitis; however, House Finches are especially susceptible to this bacterium, which led to serious declines in North American populations in the 1990s.”
Cornell Lab of Ornithology, Project FeederWatch
Bird flu
“Bird feeders are unlikely to result in increased spread of avian influenza since the species of bird that tend to come to feeders are not commonly infected.”
U.S. Fish and Wildlife Service
“However, feeders do concentrate passerines and increase the risk of transmission of other infectious diseases that do impact their health, including salmonella, E. coli and mycoplasma.”
U.S. Fish and Wildlife Service
Planting
“Creating natural spaces that attract birds to the cover and food provided by native vegetation appropriate to the location is far healthier than feeders.”
