Keep seed feeders clean even in winter

Have you wondered why birds sometimes don't eat from the bottom rungs of a feeder?

The seed may be too old. Birds choose not eat seed that is clumped at the bottom of a feeder.

Try this, especially with finch feeders: Start with fresh seed. The next time you need to refill the feeder, mix any leftover seed with new seed. Then refill. This technique keeps old seed from getting moldy and yucky in the bottom of the feeder. 

If the bottom of your feeder already has clumps of spoiled seed, disassemble the feeder. Dislodge any those clumps from the seed tube. Then use a stiff tube brush to push out any remaining residue. 

Place the feeder in a bucket or sink with one part bleach to ten parts hot water. Scrub away any dirt that may be present both inside and outside. Make sure to clean the perches, feeding ports and platforms.

Be sure to rinse each piece thoroughly. For the best rinse, hold each piece under running water for at least 10 seconds. Allow each piece to air-dry thoroughly until all moisture is gone. Then reassemble the feeder.

When cleaning a feeder, be sure to wear rubber or latex gloves for protection. And wash your hands thoroughly after finishing the job.

A feeder that is too difficult to clean should be replaced with a new feeder.

Keep in mind that bad seed can sicken birds. They may want to avoid eating bad seed but in harsh winter weather they may turn to any food source they can find—even one that isn't appealing.
