The nest-site selection and nesting success of Eurasian Nuthatch (Sitta europaea) were studied two habitats, suburb of Beijing and Zuojia Natural Reserve, in northeast China from 2004 to 2008. Nuthatches in the study area bred mostly in the deciduous stands. The frequency distribution of nest-cavity orientation was biased toward the southeast and the south. Nuthatches selected nest sites with larger diameter of trunk at nest height, higher canopy cover, and shorter distance from the nearest forest edge. The rate of breeding success was 65% (N = 86) in tree holes, and was 70% (N = 23) in nestboxes. Failed nests were often results of nest-site competitors (competitors which accounted for 54% of such losses, N = 30). Sixty percent of nests were lost to White-cheeked Starlings (Sturnus cineraceus). In contrast, nest predation only accounted for 16%. Successful Eurasian Nuthatch nests were concealed and far from edges.
