Cuculinae

Cuculinae is a subfamily of birds within the family Cuculidae, which includes the cuckoos. This subfamily is characterized by its brood parasitic behavior, where the female cuckoo lays her eggs in the nests of other bird species. The eggs laid by Cuculinae species are typically similar in size and color to those of the host species, which helps to increase the chances of the cuckoo's offspring surviving. The young cuckoo chick, once hatched, often mimics the calls of the host species to avoid detection and to obtain food from the host parents.

Cuculinae includes several genera, with the most well-known being Cuculus, which contains the common cuckoo. Other genera within this subfamily include Clamator, Cacomantis, and Chrysococcyx. These birds are found in various habitats across the world, including forests, grasslands, and even urban areas. They are known for their distinctive, often loud, calls and their ability to adapt to a wide range of environments.

The brood parasitic behavior of Cuculinae species has been the subject of much scientific study, as it provides valuable insights into the evolution of bird behavior and the dynamics of bird communities. Despite their parasitic lifestyle, Cuculinae species play an important role in the ecosystems they inhabit, helping to disperse seeds and control insect populations.
