One of the biggest investments in a species life goes towards reproducing and raising offspring. Most species will spend lots of time, energy, and resources into raising their offspring and can be costly to their own survival. Although some parents will risk about anything to successfully raise their young and increase their fitness. How much time and energy is spent on raising offspring greatly varies among species and mostly depends on their evolutionary history. Brood parasitism is a mischievous way for a parent to avoid raising its own young, which can provide many advantages. However, this behavior has not always been so advantageous and has been shaped through environmental pressures. The bird family Cuculidae has perhaps the most diverse breeding strategies within any other bird species and has long puzzled biologists (Rothstein, 1990). One of the major breeding strategies within the Cuculidae family is brood parasitism. Brood parasitism is the manipulation of a host, of either the same species or a different species, to raise its young (Soler and Møller, 1996). This widely practiced behavior within the Cuculidae family of birds has been shaped due to environmental changes and coevolutionary relationships with other bird species (Briskie et. al, 1992). Among the 136 species of Cuckoo birds, 53 of them perform brood parasitism (Krüger and Davies, 2002). Of these 53 species, the most widespread within all of Europe is the Cuculus conorus, which is know as the common
