Southern Screamer
The Southern Screamer ('Chauna torquata') is a large, gray marsh bird, which despite its bill shape, is related to geese and other waterfowl.
They can be 83 to 90 cm (33 to 35 in) long and weighing about 4.4 kg (9.7 lb). They mate for life and their loud calls may be heard up to 3 km (2 miles away).
In this image you can see the carpal wing spurs which males use to fight for females and both sexes can use them for defense against predators.
I most often saw them perched in pairs at the tops of trees or flying in the sky while calling.
