Ideas about where I can find more info about this-SEGUSA/MURANO

Purchased this item a few years ago. We think it is very unique. Marked Segusa Murano Italy arte vetro. We don't know much about this except that that Segusa is a leading family name in Murano glass. We would like to find out more about this. Someone has aleady asked if they can purchase this, but I don't think I want to part with these lovely birds. It looks gorgeous on our dining room table...thank you for any info you can give to me.
