 abstract={We report a case of unusual mixed nesting association of several pairs of Spanish Sparrows "Passer hispaniolensis" and one pair of Lesser Grey Shrikes "Lanius minor" near Pepelište village, central Macedonia.All nests were built near the trunk of a Black Locust "Robinia pseudoacacia" at a height of ca.8 m. Although the nests of both species were in close proximity, we observed no interspecific aggression. Such a mixed colony could be advantageous for both species in a locality with abundant nest predators.},
