Placing a potato in bird feeder areas draws in fruit flies and gnats that your hummingbirds catch for protein. Most people don't know that hummingbirds need bugs along with their nectar to stay healthy. A rotting potato near your feeder pulls in the tiny flying insects your birds hunt every single day. It's a cheap, simple trick that makes your feeder setup more complete for your visiting birds.
I tried this last spring after reading about it on a birding forum. I cut a russet potato in half and set it cut-side down on a small plate about 4 feet (1.2 meters) from my feeder. By day two a small cloud of fruit flies gathered around the potato on the plate. By day three I watched an Anna's hummingbird make quick passes through that cloud and snap up bugs mid-flight with its bill. My feeder area got much busier after I added the potato. I counted more visits that week than any other week before it.
In my experience, the effect was even stronger during nesting season in my yard. I noticed a female hummingbird spending extra time near the potato catching insects for her chicks back at the nest. She would grab 3 or 4 bugs in a row before flying off each time. You can attract insects for hummingbirds this way right when your birds need the extra protein most for raising their young ones.
The science backs up what I saw in my own yard. The U.S. Fish and Wildlife Service says insects make up as much as 20% of what hummingbirds eat each day. Your nectar gives your birds fast energy, but it lacks the protein, fats, and amino acids they need to stay strong. A softening potato draws in the small flying bugs that fill this gap in your birds' diet. Think of it as adding a protein bar right next to your sugar drink station for them.
Your hummingbirds hunt fruit flies, gnats, aphids, and small spiders either in the air or off leaves and bark. These tiny creatures are a key hummingbird protein source all year round. During nesting season your birds' need for protein gets even bigger than normal. Mother birds feed their babies a mix of nectar and small bugs to help them grow flight feathers and build strong muscles. Your potato trick helps your nesting birds find that food right in your yard without having to search far from the nest.
Setting this up takes you almost no effort at all. Cut a potato in half and place it cut-side down on a small plate or saucer 3 to 5 feet (0.9 to 1.5 meters) from your feeder. The exposed cut side breaks down faster and puts off the starchy smell that draws your flies in. Swap your potato out every 3 days before heavy mold forms on top. If wasps or yellow jackets show up at your potato, move it farther from your feeder. You can also pull it for a few days until the stinging pests leave your yard.
Overripe bananas and melon rinds work the same way if you don't have a spare potato in your kitchen. The goal is just to have soft organic matter near your feeder that pulls in small bugs for your birds. Keep whatever you use on a plate so you can toss and swap it fast without any mess in your yard. This small step turns your feeding area into a full food source. You'll cover both sugar and protein for your hummingbirds without spending a dime extra on your setup.
