This is a really sweet story (thanks to Jan in Wales for the heads up).
Sisso the Swift damaged his wing seven months ago. He is now being cared for at the Ramat Gan Safari Park Animal Hospital in Israel
They've made a red tube-like vest made of bandages and gauze pads, Sisso has holes for his head, wings, feet and tail. This is attached by a string to the ceiling and Sisso is able to practice his flying and strengthen his injured wing at no risk.
Every hour staff feed him insects.
