Dunnock two or three adjacent female territories overlap one male territory, and so polygyny is favored, with the male monopolising several females. Polygynandry also exists, in which two males jointly defend a territory containing several females. Polyandry, though, is the most common mating system of dunnocks found in nature. Depending on the population, males generally have the best reproductive success in polygynous populations, while females have the advantage during polyandry. Studies have illustrated the fluidity of dunnock mating systems. When given food in abundance, female territory size is reduced drastically. Consequently, males can more easily monopolise the females. Thus, the mating
Kite (bird) Kite (bird) Kite is a common name for certain birds of prey in the family Accipitridae, particularly in subfamilies Milvinae, Elaninae, and Perninae. Some authors use the terms "hovering kite" and "soaring kite" to distinguish between "Elanus" and the milvine kites, respectively. The groups may also be differentiated by size, referring to milvine kites as "large kites", and elanine kites as "small kites". A few of the traditional Perninae" "are also called kites. In 1824, Vigors proposed five divisions or "stirpes" of the family Falconidae: Aquilina (eagles), Accipitrina (hawks), Falconina (falcons), Buteonina (buzzards) and Milvina (kites, containing two genera "Elanus"
