Deskripsi
Non-parental helpers contribute to offspring care in many species; however, the amount of care provided varies considerably across species. Here, Green et al. perform a phylogenetic comparative analysis of helping behavior in 36 cooperatively-breeding bird species and find that helper effort increases with relatedness to the recipient of care.
