We tested ability to adjust nest defence in the red-backed shrike. We presented dummies of three species of adult bird predators (sparrowhawk, kestrel, and long-eared owl; differing in the potential danger for the defending birds), plus two species of nest predators (jay and magpie; differing in the proportion of nestlings of small passerines in their diets). A dummy pigeon was used as the control. Shrikes regularly attacked all of the dummies tested, with the exception of the magpie and pigeon.
