Feeding birds month is wrapping up. The last thing to think about is when to stop feeding birds. Dr. Brittingham notes that feeding into spring may allow you to see some migratory birds on their fly through, and the birds that are normal “PA residents” in the spring and summer, but leave for the winter.
She suggests you keep an eye on the area you’re using and if you start to see mold or mildew, to stop feeding, or change your feeding area. Typically in the spring there’s more moisture from melting snow and spring rain. Things might get moldy, and you’ll want to prevent it from becoming a problem.
She also states that if a bear visits your feeders, you need to stop feeding. Bears coming out of their winter hibernation are really hungry and your bird feeder is an easy source of yummy calories.
