Thank you for letting me know, I was convinced he was a boy but the shop thought otherwise. We are still thinking about names and haven't decided yet. I think it may be his 1st molt as his rings in his eyes are still quite faint and the shop keepers thought he was still quite young.
The photo does not do him justice, his olive colouring is amazing.
He ate a huge portion of seed yesterday which is great for his 1st day with us. When he is more settled I will take some more photos.
