Mid-size cockatoos, such as the Citron Cockatoo, also known as the Lesser Sulphur Crested Cockatoo, and the Eleanora Cockatoo, known as the Medium Sulphur Crested Cockatoo, are usually between 14 and 15 inches long. A slightly larger cage than what is suitable for a small cockatoo should be used for these larger birds. A medium sized cockatoo needs a cage that is at least 29 inches deep, 46 inches wide and 6 feet tall.
