Southern Screamer

The Southern Screamer (Chauna torquata) also known as the Crested Screamer, is a bird species found in Peru, Bolivia, Paraguay, Brazil, Uruguay and Argentina. Its habitat is swamps, estuaries, and pool coasts. It is a permanent resident and non-migratory.

This is the largest screamer on average. It is 33 to 38 inches long and weighs 8.8 to 10 pounds. It is a good swimmer and excellent flier, though it prefers to move on the ground. The bony spurs on their wings are used for protection against rival screamers and other enemies. They are normally seen in pairs but sometimes gather in large groups if there is a food in one place. Its diet consists of plants stems, seeds, leaves, and, rarely, small animals.

It establishes monogamous relationships that last a lifetime. Its lifespan is estimated to be 15 years. The couples nest in inaccessible places using platforms of reeds, straws and other aquatic plants. The female lays between two and seven white eggs. Incubation takes 43 to 46 days and the couple takes turns during this period. The chicks leave the nest as soon as they break the eggshell but the parents take care of them for several weeks. The fledging period takes 8 to 14 weeks.
