Southern screamers may look awkward but they are very good swimmers and fliers. They have strong powerful wings. Each wing has a small spur on it which the bird can use to protect itself and flightless young from predators. Luckily despite their size, they are rarely hunted for meat as their spongy flesh is not very tasty. This bird measures up to 94 centimetres and weighs up to 4.5 kilograms.
Instead, they act as a guard and their screams can be heard more than three kilometres away if they are approached by hunters. They have very large feet with long toes that stop them sinking in marshy ground.
