Abstract

Abstract Cooperative animals share different activities during reproduction, but individuals of a social group may invest in these tasks in different proportions. Nest sanitation is an important task that may impact reproductive performance of birds, and yet, little is known about the relative participation of individuals of a social group, particularly in non-passerine species. Here, we describe nest sanitation behaviour and materials removed, and test the occurrence of task division regarding faecal sac removal in Campo flickers (Picidae), a facultative cooperative breeder with complex social system. We found that helpers removed proportionally more faecal sacs than breeders, and male helpers are mainly responsible for this activity. These results are different than the commonly reported patterns for passerines, where females are the main contributors. Different ecological conditions and benefits achieved by group members may influence their investment in nest sanitation, but additional studies on social species could greatly contribute to our understanding of how general our results are in non-passerine species.
