Welcome, Bando. Why do you think it's ancient? I did a quick search, and there are a million of these "Greek owls" out there. Unless you dug it yourself out of the Grecian rubble, I would say likely a tourist piece. Good luck.
Welcome to Tnet from Toronto bando!
I found a similar brass owl years ago in a park.
Like yours, I would assume these are just modern decorative pieces... the hole near the bass is interesting?
It's brass that's had an acid applied to give it a faux aged patina. Novelty items like these are often sold at museum shops that have exhibits of the genuine ancient artifacts on display.
