EDIBLE & NUTRITIOUS: there are 22 basic elements in a bird’s body: enzymes, hormones, vitamins, amino acids, and more which must be renewed by diet. No single food contains all of them except Bee Pollen. That's why we designed the Tooty Fruity Perch which comes in 3 great flavors: Grape, Watermelon, & Kiwi-Lime. SEVERAL SIZES AND FLAVORS: choose from Watermelon, Grape, or Kiwi-Lime. Small is 5.5” long x 1” in diameter and great for Parakeets, Cockatiels, Lovebirds, Parrotlets and other birds similar in size. Medium is 7.5” long x 1.5” in diameter and great for Amazons, African Greys, Eclectus, and other birds similar in size. Large is 10.5” x 2” and great for Moluccan Cockatoos, Macaws, and other large parrots. VETERINARIAN APPROVED: we developed these perches with advice from an avian veterinarian. Calcium carbonate is added because most avian veterinarians recommend calcium supplements for pet birds. MADE IN USA: by a family owned & operated facility in Warner Robins Georgia who loves birds. This comfy & lightweight perch can be installed on virtually any size cage. VITAMINS & MINERALS: Bee pollen contains small amounts of Manganese, Iron, Phosphorus, Zinc, Copper, Magnesium, Calcium, Potassium, Sodium, Nickle, Boron, Chromium, Molybdenum, Iodine and Selenium.
