The Butterfly section was absolutely boiling (Hence the "tropical" bit of Tropical world I guess!) but had some beautiful species of butterfly and moth fluttering around our heads. I managed to get a few photos of them as they settled on the flowers and hand rails.
Meerkat watch tower - this little fella had the duty of keeping a lookout while everyone else snoozed... someone got a bit of a bum deal!
All of the birds (like the butterflies) flew freely around the exhibits and as they were obviously very used to having humans around them they posed happily for my photos not in the least bit frightened.
