The perch most often utilized by your pet, i.e. the one upon which it roosts for the night, should be of a width that allows the bird’s toes to go about ¾ of the way around. A variety of perches of other widths should also be included in the cage, and these should be made of differing materials. Following are some perch characteristics, along with suggested products:
Natural wood perches provide both a variety of grip widths and a chewable surface.
Cement perches are valuable in keeping nails trimmed but should not be used as your pets “main” perch. A good place for these is near the food bowl, so that they are used daily but not exclusively.
Rope and cable perches provide a unique surface upon which to grip and perch and encourage birds to exercise the muscles in their feet (especially if placed at varying slanted angles).
