Toucoatlus

Toucoatlus is a sauramphastid endemic to North Alor during the Late Hesperocene period. Despite it's name, toucoatlus isn't the scientific name of this animal, but a common name. To avoid confusion, it is sometimes referred to as the greater dinoucan.

Description
The largest known bird to ever live on Chaoterra, the toucoatlus has a wingspan of more than half of a quetzalcoatlus' wingspan, being up to 5.5 meters (18 feet). Reports about the toucoatlus placed it's wingspan of up to 6.2 meters (20.3 feet), though studies suggest a maximum wingspan of 6.3 meters (20.6 feet). Further advanced studies lowered these estimates to around 5.8 meters (19 feet). The weight of these behemoths measure up to 63.5 kilograms (140 pounds).

Diet
The toucoatlus is a carnivore that hunts medium-sized animals. Although feeding on other sauramphastids, reports of its dietary habits demonstrate a wide variety of prey selectivity and specialization depending on habitat and season. It's long beak suggest that it may also feed on marine creatures such as krayt serpents. Vertebrates consumed ranged from fellow dinoucans to a wide variety of mammals, namely primates.

Behaviour
The toucoatlus is a highly territorial creature. It marks its territories by scratching the barks of trees. Fights over territories will only end if one manages to drive away another toucoatlus. During the mating seasons, males will gather in large groups and will fight over eachother for the females. The toucoatlus displays a form of parental care, and mothers are highly aggressive towards rival females and predators when it comes to defending the chicks.

Reproduction
The toucoatlus lay over 4 eggs in a nest in which all emerge as naked chicks with no feathers. For about 6 years of age, the young toucoatlus are able to fend themselves from predators.
