Large grey bird with a small head and hooked bill. There’s a black ring around the neck and red circles around the eyes. The long, thick legs end in slender toes with only partial webbing. Two sharp spurs protrude from the forward edges of each wing. Screamers take their name from their loud call that can be heard two miles away. When not nesting, screamers live in large flocks of up to 100. They are good swimmers but prefer to move on the ground. When in danger, they often retreat to treetops where they can view the disturbance from a distance. Although they are non-migratory, they are excellent fliers, sailing in circles until out of sight. They are somewhat nomadic and tend to form large flocks when searching for food.
Adaptations: The spurs protruding from their wings are made of bone and used for defense. Although loss of habitat and human pressures threaten screamers, they show their ability to adapt by foraging in cultivated fields.
