In some areas they are kept among flocks of chickens to protect them against snakes.

They are threatened through capture for food and pets.

Across the rest of the body they have finely barred plumage which is colored brown. Around the neck, breast and underside these are rather loose. At the base of the bill is a crest of feathers which are permanently raised. On the upperside the feathers are colored whitish turning to grey on the head and neck.

Diet

What does the red-legged seriema eat?


The red-legged seriema is a carnivore. They will feed on a range of animal prey including birds, reptiles such as lizards and snakes and small mammals such as rodents.

Due to their ability to kill snakes they may be kept in some areas of their range among flocks of chickens to help protect them.

They have shown the ability to consume venomous prey including snakes.

Before consuming prey it is caught and banged against rocks which will help to kill it and break its bones making it easier to eat.

Reproduction

How does the red-legged seriema produce its young?

Breeding takes place during the rainy season which varies in its occurrence across its range.

At the beginning of the breeding season the males will display for the females by extending their wing feathers and strutting in front of her. If two males are targeting the same female they will engage in fights.

Once they establish a partnership the pair will duet with one another.

Their nest is built in low branches of a tree. It is formed from branches and then lined with mud and leaves. Adults build it low in the trees so they can reach it using short hops.

In to the nest the pair will deposit two eggs at a time which are colored white with brown spots. The female completes the incubation which lasts 27-28 days. At hatching the young are covered by long brown feathers.

Fledging takes place between 12 and 15 days old.

Sexual maturity is reached between four and five months old.

Behavior

What does the red-legged seriema do with its day?

A range of vocalizations are produced by the red-legged seriema including a loud yelp which includes various changes in pitch.

These calls can carry over long distances and are used by males to defend their territory. During these displays the male will fling his head back far.

In short bursts they can reach speeds of up to 40km/h (25mph).

This bird rarely flies. They will use rapid wing beats followed by glides to carry them over short distances.

Predators and Threats

What is impacting the survival of the red-legged seriema?

When threatened by a predator they will lie down and hope their coloration provides effective camouflage.

In most areas this species has benefited from habitat loss as it creates more of their preferred habitat types.
