The Guira Cuckoo is a highly social, gregarious bird that often moves and forages in noisy groups. It practices communal nesting, with several females laying eggs in a single stick nest and multiple adults helping to rear the young. Its shaggy crest, long tail with white tips, and orange-yellow bill make it easy to recognize. It is largely a ground and low-perch forager and has relatively weak, gliding flight.
