The cuckoo family of birds is interesting for many reasons. While some of the facts about the bird are overblown, such as their reputation as parasitic birds, there is some truth to the lore. Some species of the family do lay their eggs in host nests, leaving the host to raise their young.

The family contains 127 species of birds, however, and many raise their young on their own. Some species lay their eggs in communal nests, sharing the responsibility. The parenting behavior of the cuckoo family is one of the most diverse and interesting facts about them.
