I've had this from the beginning of '80s when my mother gave it to me, she must have bought it herself or been given it as a gift around the '70s. She can't remember it now I asked on the phone, must send her a picture, but she's old... just can't remember everything.

I found information of the ZBS factory/school already from this site. Just great.

And a very much similarly coloured bird Della has posted in this message
http://www.glassmessages.com/index.php/topic,18268.0.html(Oh,not "egret" but "cormorant" ! I am learning birds in English from a glass site...)

Anyway, I cannot say "egrets, I've had a few", nor cormorants. I only have this little birdie and I do not know if it is a green bullfinch or what?
And is it just another piece from the factory or would there be a designer or any other information available?
