Interesting!!!! Since a customer asked me to engrave this bird on the fowler that I'm working on, My first thought was maybe an eagle, or a peacock, but I got to thinking something is different, and I would like to believe what Smartdog suggested a dove with olives leaves, but then others have mentioned it being a Phoenix, and I'm like what is a Phoenix?? So i googled it, and here is the result. shttps://www.google.com/url?sa=i&url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FPhoenix_(mythology)&psig=AOvVaw28M5uD5ZkcO4Uv7UZT8R5s&ust=1612887861825000&source=images&cd=vfe&ved=0CA0QjhxqFwoTCJDA_fDZ2u4CFQAAAAAdAAAAABA
With that tuft on the back of its head and the outspread wings , with a ball of flames below its feet or at it; would seem more likely.
I still learn everyday, and my options are still open..
