It was searching a lot of images and very similar birds attributed to AS but I know 80% of 'Murano' on line is not Murano. I know its difficult without signatures to find a maker other than Murano. I am having the same problem with the other pieces I have

Here are a couple of daylight pics...
My first port of call with animals is always Anita's Murano Zoo, even if it is just to look at the glass

Some great pieces I would like to see in the flesh. A lot of the birds are similar in style so more searching needed I think. Thanks John.
