Years of research has determined that our Parrots will be healthier, more active and more confident when flighted. The harness has an elastic restraint so as not to do any harm when they reach the limits of the harness. The extra small harness fits Parrots from 110 - 190 grams such as Quakers, Senegal, Doves, Medium Parakeets (Indian Ringneck, Port Lincoln) Rainbow Lories, Rosellas, Noble Macaw, Large Conures (Suns, Jendays Nanday, Blue Crown), Caiques. The one piece design makes it easy to put on and it comes with full instructions on a DVD. Add a Flight Line that is a tangle proof system allowing up to 250 feet of flight area.
