Before revision: The nearest and next-to-nearest neighbour spacings between buzzard nests in the Teutoburger Wald around Bielefeld, as gathered in the years2000--2019, are compared with Ginibre random matrix ensembles as well as the Poisson spacing distributionin two dimensions. Our goal is a phenomenological description of some structural aspects in the territorial behaviour of these birds. To capture intermediate spacings between Ginibre and Poisson, we also compare to numerically generated two-dimensional Coulomb gases at different temperatures, which interpolate between the two.
After revision: The nearest and next-to-nearest neighbour spacings between buzzard nests in the Teutoburger Wald , Germany, as gathered over a period of 20 years. The nearest and next-to-nearest neighbour spacing distribution between nests is compared to the two-dimensional Poisson distribution, originating from uncorrelated random variables, to the complex eigenvalues of random matrices, which are strongly correlated, and to a two-dimensional Coulomb gases at different temperatures, which interpolate between the two.
