Abstract

Male rock sparrows differentially allocate nest defence but not food provisioning to offspring Giuliano Matessi 1,3) , Cristina Carmagnani 2) , Matteo Griggio 2) & Andrea Pilastro 2) ( 1 Animal Behaviour Group, Department of Biology, University of Copenhagen, Universitetsparken 15, 2100 Copenhagen Ø., Denmark; 2 Department of Biology, University of Padova, Padova, Italy) (Accepted: 13 June 2008) Summary Secondary sexual characters may provide information about individual quality to a partner, which may use it during parental care to strategically allocate resources to the current breed- ing attempt (Differential Allocation Hypothesis). Differential allocation by females has been demonstrated for a number of species, while male differential allocation based on female secondary sexual traits has received less attention. Yet females of many species, among birds in particular, are ornamented. We performed a test of male differential allocation based on a female ornament in the rock sparrow ( Petronia petronia ), a monomorphic species in which both sexes have a yellow breast patch, the size of which correlates with individual reproduc- tive quality.
