Thank you both

That sloth one was the only one out of about 20 shots that was any good. The trouble with Rainforests are they are so dark and hand holding at 400mm even in bright light isn't easy

And that tree frog was pretty much the only frog we saw (considering costa rica is renowned for its variety of tree frogs and poision arrow frogs which I really wanted to see) and it was outside our hotel window.

They have about 40 species of humming birds and at one place the air was just vibrating from the buzz as about 20 hummingbirds zoomed past your head. It was quite a magical experience.

Working in a lab unit at The Prince of Wales Hospital, Randwick, Sydney. Doing what exactly... I don't know
