Behaviour
Dives frequently for fish, which it spears with its long sharp bill, then tosses them in the air until it can swallow them headfirst. The colloquial name, Snakebird, can be quite descriptive when this bird is in the water - it swims with its body mostly submerged, and just the long sinuous neck above. On quick glance, it can thus appear to be a swimming snake. The other common posture is on a tree near or over water, where it spends hours with wings extended, drying in the sun; unlike ducks, it has no oil with which to waterproof its feathers, an adaptation to improve its diving ability. Monogamous.
