Manzanita is a safe, non-toxic hardwood. Its natural curving and irregular shaped branches contribute to your birds healthy feet and overall happiness (very important for a bird that is on it’s feet all day). Bird perch diameter is the most important part of choosing a Manzanita bird perch . Your birds feet should rest on the top half of the perch. A perch that allows your bird to wrap its feet around the perch is too small.Using Manzanita bird perches allows your pet bird several different diameters on one perch, helping to exercise their feet and improve foot strength and dexterity. See our sizing chart for the diameter that is right for your bird.
