you can see the flamingo, they're just inside a holding pen right now, look for the new shed next to the duckpond. As long as they're not hiding from the cold inside the shed you'll get a decent look at them, there appears to be 6 in total. Unfortunately the Agouti aren't out yet.
Having looked again today i'm not sure if the new structure near the red river hogs is going to be a play area or a part of the new walkway, or even something else. Would be nice to find out. Seemed to be some clearing / building activity starting to the side of the wetland reserve (behind the camels) which would fit in with the recent plans being approved.
I think the last entry at this time of the year is around 3:30pm. There was only one set of lions out again today though, they seem to be rotating them at the moment.
