Thanks Eric, that's exactly what I was trying to describe, and yes Ryan it's so much easier if you can get close to the fence to focus through a gap. It's very difficult with other animals like lions and tigers at a zoo which normally have multiple fences to not only protect the animal but the visitor as well.
Well done you guys, they arre both stunning photos of birds in captivity. I went to a bird sanctuary a while back and you could get some great photos because the birds were tethered on perches with no fences.
