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.

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