Custard Glass Ceiling light fixture with bird and branch

I’m not finding the exact same bird either. Most of what I’ve seen says Art Deco. I’ll leave links but may be the same ones you’ve found. Some are quite different but I think of the period. https://www.rubylane.com/item/784975-P-1312/Antique-Custard-Glass-Pendant-Blue-Bird https://www.worthpoint.com/worthopedia/1920s-vintage-art-deco-custard-glass-441164107 https://www.worthpoint.com/worthopedia/vintage-custard-glass-light-shade-479433346 https://www.worthpoint.com/worthopedia/antique-vintage-art-deco-parrot-glass-1929522968 https://picclick.com/Vintage-Art-Deco-Custard-Glass-Pendant-Light-Shade-391998092641.html https://pin.it/6YItWnz I’m not an expert, just googling stuff but I wonder if the ones that are all alike might be reproductions based on yours?

Thanks. My concern since I can't find them is that they're a reproduction, or maybe custom but not necessarily old.
