They tend to benefit from human disturbance of the landscape, especially clear-cutting rainforest, as it opens up more habitat for them. Social Behavior . The guira cuckoo reproduces in community-based groups in which several females lay eggs in a single nest which can contain more than 20 eggs and is built high up in the trees.
