Discuss Abdirahman's answer to: Bird Grooming

To be safe, caged birds should have their wing feathers trimmed. The decision to deny a caged bird free, unrestricted flight (as in the wild) is made by each bird owner at the time the bird is made a captive pet in the home.

Wing trimming makes a bird's cage confinement safer. Flight feathers of both wings should be trimmed. If your bird escapes its cage and takes flight, its descent to the floor is balanced and relatively controlled. Trimming the feathers on only one wing results in an unbalanced descent to the floor, possibly injuring the bird.

Another disadvantage is that many birds with only one wing trimmed can fly as soon as 1-2 flight feathers have grown out on the trimmed side. Some bird owners prefer not to trim the wings of their smaller caged birds (parakeets, cockatiels) because their flying brings the owner great enjoyment. These small caged birds have a smaller turning radius in flight than the larger ones. Consequently, the smaller birds can usually safely fly about most homes and apartments. One other advantage of not trimming the wings of these small birds is that it allows them to escape when in danger and threatened by any pet in the home.
