Common name:

Order Anseriformes
Family Anhimidae

This South American species is found in south-eastern Peru, northern Bolivia,Paraguay, southern Brazil, Uruguay and northern Argentina.

Southern screamers are 83-95 cm long and have a wingspan of 170 cm. They weigh 4-4,5 kg.

These birds are found in marshes, grasslands and lagoons.

The diet of the southern screamer consists of plants stems, seeds, leaves, and, rarely, small animals.

These birds are monogamous, forming stable relationships that last their lifetime. They breed in September-December, building a large stick and reed nest on the ground near shallow water. There the female lays 2-7 white eggs which are incubated by both parents for 43-46 days. The chicks leave the nest within a few hours, and fledge 8-10 weeks after hatching. The parents care for the young and they only become fully independent 14 weeks after hatching.

IUCN status - LC (Least Concern)
This species has a very large breeding range and a global population of 100.000-1.000.000 individuals. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
