One of mine popped out in the early years never to be seen again,,,(no pun intended) (( well ok maybe a little one)) these glass eyes are just fitted into the socket, form fitted. But the funny part is I have been getting away with this one eyed bird for years by putting a large seed in the socket that had the eye missing,(The large brown seed from their millet) no complaints yet.. These are a good rubber dove prop. If anyone has a spare eye please send me one!!!!

Chris I've been doing some taxidremy work and I'll bring you a catalog to the next meeting it has all size of glass eyes in it so you should be able to match up with your good eye.

Thanks Alan.... I will keep an eye out for you at the next metting
