Will my bird damage the cord attached to my harness?
The design of the Aviator Harness makes it unlikely that your bird will be interested in the leash and cause any damage. However, 400,000 Aviator Harnesses sold has provided us with a great deal of feedback.
Our choice of shock cord is difficult to chew through. It has a knitted nylon sheath that is very damage resistant. It is sort of like the difference between cutting a cotton t-shirt and a sweater. The sweater is much more difficult to cut through in one pass. We also have multiple rubber bands inside so they will not all be broken at the same time. Instead of the standard white rubber we use black. If the cord is damaged the rubber is the same color as the sheath and much less likely to hold your birds attention.
The position of the clasp that attaches the shock cord to the belt has also been well researched. Each size has a specific distance form a bird to the clasp that connects the shock cord.
With a little outside time experiencing freedom and flying longer distances your bird will become comfortable and have no interest in flying away, as well as becoming more used to the leash extension.
