Individual birds are expected to maximize their fitness by directing their chick-feeding effort only towards broods containing closely related nestlings. We tested this prediction using data from the cooperatively breeding Arabian babbler, Turdoides squamiceps. Individual chick-feeding effort, in the form of visit rates and load sizes delivered to the nest, was compared with three measures of relatedness: (1) band-sharing coefficients derived from multilocus minisatellite DNA fingerprints; (2… CONTINUE READING
