A healthy wetland teams with life. Australia's Northern Territory is the home of Kakadu National Park and Mamukala Wetland.
As twilight falls, thousands of birds flock into the wetland for the night. Life surrounds you in every direction.
Magpie geese are an iconic species of Australia's northern monsoonal wetlands. Their black and white plumage is hard to miss, but on this day they were all smeared reddish-brown from feeding in the mud.
An ancient species they diverged from the evolutionary branch containing all other modern water fowl in the late Cretaceous. They have a prehistoric look and as the only existing member of their primitive family, they are a living fossil. At the water's edge two pied herons hunt for small invertebrates and fish.
At the edges of the wetland wallabies forage. The droppings from thousands of birds nourish a rich green tapestry of plant life.
Kakadu is a treasure of wildlife diversity and human spirituality.
