How (and Why) to Clean Your Winter Bird Feeder

Winter months might not seem like the best time for backyard birding, however savvy birders know that colder months can bring an abundance of feathered activity into your yard. Providing food is perhaps the easiest way to attract winter birds, and it can also help them survive the winter season. Well-fed birds are able to withstand the harsh rigors of winter by staying warmer than those unable to find reliable sources of food. When feeding birds, it’s important to remember to keep feeding stations clean, even in the coldest winter months.

Dirty bird feeders, especially during warmer winter days when the snow melts, are a breeding ground for disease that could decimate entire backyard bird populations. Rancid seed can also attract unwanted backyard wildlife such as mice, rats, raccoons, and opossums. In addition, spoiled seed will cause wood decay and difficulty in cleaning the feeder. Caked seed can clog feeding parts, hinges, and other parts causing it to crack, warp, or break. So clean those feeders!

How Often Do I Need to Clean?

How often you need to clean your bird feeder is dependent upon the style and frequency of its use. Plastic, metal and wooden feeders should be cleaned a minimum of once per month, more if the stations are used frequently. Because mold can readily grow in sugar water, nectar feeders, like those for hummingbirds, will need a cleaning every time they are refilled. If you see any sign of cloudy water or black mold, discard the solution and clean the feeder immediately.

How to Clean a Winter Bird Feeder - Care2

Things You’ll Need

  • Fragrance-Free Liquid Soap
  • 4 cups White Vinegar
  • Water
  • Scrub brush and/or bottle brush depending on style of feeder
  • Large plastic cup (to use in place of a garden hose during rinsing)
  • 1 – 2 inch putty knife
  • Container for waste

Step-by-Step Directions

1. Prep the Area. Colder weather means you won’t be cleaning your bird feeders outdoors. Instead, clean bird feeders in a garage or other utility area that has access to water. If you don’t have access to this type of area, you’ll need to wait for a mild winter day so that you can clean your feeders outdoors. Find a bucket or tub large enough to soak the bird feeders in. Lay a few towels on the ground nearby, enough to set all the feeders on. Gather remaining supplies.

2. Remove Old Seed. Removing old or wet seed from feeders is important, particularly in thistle and tube feeders where the seed is easily compacted. Give the feeders a shake over the waste container to help dislodge the seeds. For platform feeders and seed trays, use the putty knife to remove clumps of old seed caught in corners.

3. Clean. Fill the bucket or tub with warm water and small amount of fragrance-free liquid soap or detergent. Scrub the parts of the feeder you can reach with a scrub brush, working from top to bottom. Using the large plastic cup, rinse the feeder thoroughly with clean water. Once complete, set the feeders on the towels nearby. Empty the bucket or tubs of water and refill with clean water. Add 4 cups of white vinegar. Let the feeders soak for one hour, then rinse in clean water. Set the feeders back onto the towels and allow feeders to dry completely. Once the bird feeders are completely dry, they’ll be ready for use again.

More Helpful Tips

  • If you are enthusiastic about feeding birds but don’t enjoy the burdensome task of cleaning the feeders, install several feeders and clean them on a rotating schedule. This will eliminate the need for cleaning the feeders all at once. Plus, more feeders equals less crowding and less sharing of disease.
  • If you decide to provide food in the winter, please keep the feeder full since many birds will come to rely on it as a regular place to visit and eat.
  • Wear gloves and always wash your hands thoroughly after filling or cleaning your feeders.
  • Keep it dry! Don’t allow large amounts of seed to become wet, especially on platform feeders. Instead, when it is wet outside, feed birds from covered stations that keep the seed dry. If this isn’t possible, only put out a small handful of seed at one time on the platform.
  • Inspect your feeding stations regularly! If you suspect that a sick bird has visited your feeders, take them down and clean them immediately. Don’t put them back up for at least a week to allow the birds a chance to disperse. Call wildlife officials if you notice that the birds in your vicinity seem sick.
  • Don’t forget to look down. Cleaning the areas under bird feeders is just as important as cleaning the feeders themselves. Remove old seed hulls and other detritus from under feeding stations and discard.
