African Wetlands ft. Lesser Flamingos

Can also see a Sacred Ibis. Challenge for someone, identify the rest of the waterfowl!

The ones swimming must be Maccoa Duck. I also see a Red-crested Pochard near the flamingoes, and what appears to be Fulvous Whistling Ducks off to the left near the waterfall. There is also another ibis in the trees. Are these correct? I don’t know what the largeish birds to the centre are.

Bit late, but anyway: whistling ducks I believe are Lessers, and there's a couple Hadada Ibis at the water's edge.
