Many thanks to all the respondents. The Aviary is actually quite secured with foliage within and without, as well as a 3/4’s roof covering. But, not enough.
The issue is the raptors have learned over the years. Original attacks usually resulted in their being stunned to literally falling to the ground after impact of flying into the ‘sun column’ of the aviary, and then the birds would hide. No harm other than the scare. I’ve had Love birds, Gouldians, a Finch potpourri over the years and have since matriculated to canaries of all sorts. An auditory avian aquarium if you will.
The generational offspring of the hawks ( this is now over about 10 + years) have learned to scare the birds once in the tower, then scare them to exhaustion by running around the sun tower till they alit to the bottom, and then attacking through the ground level.
I’ve doubled layered the perimeter wire, except for the entry door. My bad.
The hawks (coopers, sharpshinned, redtail) have learned to wait at the doors ground level and the reach through the 1/2” by 2” galvanized wire and try to pull the exhausted birds, or dead ones from a broken neck, through the slats (they don’t get much, likely the thrill of the hunt more). Only learned this behaviour from a Ring install with a different perspective view.
Long to short, I wrapped the tower (3’ diameter by 6’ tall) with a 4” offset of visible bird netting as an initial deterrent, and then used 10’ long x 12” spaced galvanized wire ‘hangers’ to dissuade the raptors from flying back to the cage door (which is under the common roof) to attack as the wires, though mobile by their singular attachment won’t allow, or will at least make them think twice of flying through them as the ‘ping’ when touched, like a harp cord.
So far so good - ha! Next, they’ll find the hidden key to the aviary lock.
Many thanks, all.
