Our BG Macaw did not destroy this right away.  Big chunky wood - Edit:  For some reason my BG just ended up ignoring this.  He did not want anything to do with it after the first couple days and usually destroys everything right away.  I don't know if there is a smell or something about it but he left it - I tried reintroducing it whenever I would rotate toys - no dice.  He won't chew it - everything else goes to toothpicks though.  This is a mystery - but I'm trusting his judgement - there's something there he doesn't like.
