Walk to where you want to watch the feeder from, perhaps from a window when you are working inside or from a favorite spot in the garden. Mentally note which locations are within your range of vision.
Investigate where local predators such as cats might lie in wait for hummingbirds, such as in dense shrubberies and underneath sheds. It is best to position hummingbird feeders at least 10 feet away from such spots. However, hummingbirds may need to retreat to vegetation themselves if there are hawks in the area, so don't position feeders right out in the open. Ten to 15 feet away is about right.
Select a sheltered, shaded site or sites out of the remaining possibilities and hang your feeder about five to 10 feet above the ground. If there are no convenient branches to hang it from, purchase or improvise a bird feeder pole. Some premade bird feeder poles are freestanding, while you must dig a hole to install others.
Look for a place that is protected from the wind, which may cause the feeder to sway and spill the sugar water solution. Also, a shady place is ideal to keep the solution from spoiling in the sunlight.
