you may know i have been harness training Biggs for a while, and i first had a feather tether. I bought an aviator recently, and today we got it on, without a squak, or a bite. in fact he was very good, but as doing the buckle is fiddly on a small bird anyway, it was the bit he was not too impressed having me do. but he still didnt attempt to bite me bless him.
it is Sal, i think as he a small bird and there are less buckles, its much more comfortable. The front buckle(the only one) is on the outside, so even thats better. The cd is really good, but based on larger birds, which looks much easier to put on.
The idea of the elastic tether works, as he did fly a couple of times indoors, but landed fine.
