The ontogeny of the pecking response of herring gull chicks, Laws argentatus, was investigated in an attempt to resolve the potential contributions of maturation, habituation, conditioned inhibition, classical conditioning and imprinting. Previous studies had shown strong innate preferences for certain stimuli, but no significant preference for herring gulls over laughing gulls, Lurus atricilla, either at birth or among older chicks whether wild-reared or laboratory trained. In the tests… Expand
Families on the spot: sexual signals influence parent–offspring interactions

It is demonstrated that the red spot in yellow-legged gulls functions as a sexual signal and indicates that parental rules are plastic, depending on the information on offer, and the incorporation of sexual signals in parent–offspring interactions can be crucial in understanding intra-familial conflicts.
