Just place the swing next to a feeder or nectar-rich flowering plant and hummingbirds will actually use the swing as a perching spot to watch over their food source! I know its hard to believe -- but hummingbirds already spend about 80% of their time perching in trees.. By placing the swing next to a feeder you can create an ideal perching spot that is closer to their food source and ultimately closer to your viewing enjoyment.
