Sparrows and other large birds like Starlings can easily take over and overwhelm a feeding area, especially with traditional stationary feeders. Also, try not to move the feeder too often because every time you move it, you start over in establishing that location for feeding. Find one good location and stick with it for at least 2-3 months. It also helps discourage house sparrows. Feed birds all year long .
Many people feed birds in the fall and winter then stop.
You will be surprised at how many birds visit feeders in the summer time. If you feed them all year, the birds will identify your area as being a reliable source of food and the number of small songbirds will increase. You will always have the pleasant sound of chickadees in your yard. Note, birds will not visit feeders nearly as much during mating season, usually around May during Spring. Clean your feeder at least 2 times a year .
