Male ornamentation and within-pair paternity are not associated with male provisioning rates in scarlet rosefinches Carpodacus erythrinus

Original language description

As proposed by the 'good parent model' for evolution of secondary male ornamentation, secondary ornaments may signal male provisioning rates and, therefore, direct benefit to females. On the other hand, male parental care intensity can potentially be affected by the occurrence of extra-pair offspring in its nest. According to 'parental investment theory', males that lose paternity in their nests should reduce their parental care. In this study, we analyse potential relationships between intensity of parental care, male ornamentation, the occurrence of extra-pair paternity and male extra-pair fertilisation success in the scarlet rosefinch Carpodacus erythrinus. Our results based on 50 observed nests indicate no effect of paternity loss on the rate of food provisioning to nestlings in scarlet rosefinches. Simultaneously, we found no evidence for an association between male ornamentation and male provisioning rates. The only male trait associated with provisioning was the ability to sire
