How Much Wildlife Do You See in a Day?

The height of the season on the main island there's over 200,000 birds. You can see in a day even though you don't record that. The river runs down here and because of the rain that's mud. And it's not a strong tide today so it's not really driving it up. Why is there that discoloration in the water? It's green up to one stage and then brown from there.
