If you actually want hummingbirds in your yard, set aside the feeder for a moment. There's a native plant they will fight each other over.
It's coral honeysuckle, also called trumpet honeysuckle. It's a twining vine native across the eastern and southeastern US, and it throws out clusters of long scarlet-red tubes with yellow throats from spring straight through fall.
Those tubes are shaped almost exactly to fit the bill and tongue of a ruby-throated hummingbird, the common hummingbird across most of the East. A feeder is sugar water you have to mix, clean, and scrub before it ferments and spreads disease. This is a plant that just makes fresh nectar every day for months.
This isn't honeysuckle the invasive stuff strangling the woods. That's Japanese honeysuckle. Coral honeysuckle is the native cousin, and it's well-behaved. It climbs a trellis or fence, tops out around fifteen or twenty feet, and a light yearly trim keeps it in line. It won't take over.
The flowers also feed native bees and hummingbird moths, the red berries that follow feed robins, thrushes, and waxwings into fall, and the tangle gives small birds cover to nest in.
