Another great hummingbird question from my friend Kate:
Where do you place the feeders? Are they okay out in the open and, if so, do the hummingbirds become too nervous to feed if they can be seen by birds of prey?
Ruby-throated Hummingbirds prefer feeding at a station where they perch and observe the landscape, and then zoom in. Typically, I recommend hanging the feeders on the lower limbs of trees and on shepherd’s hooks close to shrubs and above perennial wildflowers, about four to five feet off the ground. I haven’t read or heard too much about birds of prey in regard to hummingbirds; they move too fast, however, bluejays are said to attack nestlings. House cats and praying mantis pose a more serious threat to hummingbirds.
The greatest threat to hummingbirds is development resulting in loss of habitat and nectar-rich wetland plants. By placing hummingbird feeders in the garden during the months when little nectar is available (April, May, and October), creating habitats in our backyards, and planting their preferred nectar-rich wildflowers help mitigate the loss of hummingbird habitat, and greatly increases their chance of survival.
