Brood Parasites

The video explores brood parasitism, where certain animals, like cuckoo catfish, wasps, and birds, lay their eggs in the nests of other species, leaving the host to care for their young. This evolutionary strategy involves various tactics to deceive hosts, such as egg mimicry and aggressive behavior. Host species have developed defenses, including egg rejection and alarm calls, to combat these parasites. However, some hosts tolerate parasitism to avoid retaliation from the invading species.
