Cuckoos (Family: Cuculidae)

Summary

In this episode, host Ivan Phillipsen dives into the diverse and sometimes mysterious world of the avian family Cuculidae. While the family is famous for the iconic call of the Common Cuckoo and cultural icons like the Cocoa Puffs mascot, it also includes a wide array of other fascinating birds such as roadrunners, coucals, couas, anis, and malkohas.

Learn about the unique biological traits and behaviors that define this cosmopolitan group. From their distinctive zygodactyl feet and plumage variations to their innate, genetically-programmed vocalizations. The episode also highlights the famous behavior of brood parasitism—where some cuckoos leave their young to be raised by other species—as well as the physical adaptations that allow others to thrive as terrestrial sprinters or arboreal skulkers.
