Northern Screamer - They are considered Near Threatened.
Southern Screamer - The Southern Screamer is a good swimmer, having partially webbed feet, but prefers to move on the ground. The bony spurs on its wings are used for protection against rival screamers and other enemies. Although it is non-migratory, it is an excellent flier. It lives in large flocks, feeding on the ground in grasslands and cultivated fields until nesting season, when birds pair off.
