The best way to keep a hummingbird feeder filled is to refill it with fresh sugar water every few days. Make sure to use an equal ratio of sugar and water, as this will help attract hummingbirds to your feeder. Additionally, you can add other natural food sources such as fruit or vegetable juice to increase the variety of foods available for the birds.
