Abstract
Our results showed that the average weight of impaled prey was greater during the last reproductive stage (hatching and feeding young), providing evidence of differential usage of impaled prey during the breeding season. We therefore hypothesize that larger animals provide more energy, then vertebrates are preferred to invertebrates, especially when parents are feeding their nestlings.
