Data from: The hawk-dove game in a sexually reproducing species explains a colorful polymorphism of an endangered bird

Hanna Kokko, Simon C. Griffith & Sarah R. Pryke
The hawk–dove game famously introduced strategic game theory thinking into biology and forms the basis of arguments for limited aggression in animal populations. However, aggressive ‘hawks’ and peaceful ‘doves’, with strategies inherited in a discrete manner, have never been documented in a real animal population. Thus, the applicability of game-theoretic arguments to real populations might be contested. Here, we show that the head-colour polymorphism of red and black Gouldian finches (Erythrura gouldiae) provides a real-life...
