|Horned Screamer (Anhima cornuta)
These large birds have a wing span of about 1.70 metres. Both sexes have a "horn" protruding from the forehead but this is quite brittle and can break off although it grows back again.
The amount of white on the neck and the outstretched wings is variable.
|They are found from Colombia to Brazil and northern Argentina. Nearly always close to water, they prefer marsh and river meadows as well as the llanos of Venezuela.
When not grazing, they often perch on low bushes and will fly up to tall trees when alarmed.
