Abstract:This paper reports on a case of selection, due to the influence of bad weather on the number of nestlings, acting through different pathways on the breeding date and morphological traits in breeding Great Tits. Multiple regression of relative fitness on tarsus length, bill height and forearm length, revealed significant phenotypic selection of male forearm length and female bill height. However, nestling mortality during the bad weather depended on their age, which suggested that the breeding date is a focal trait for selection. The multiple regression analysis of relative fitness on both body traits and the hatching date shows that in males only the breeding date was significantly related to fitness, and forearm selection resulted from the correlation of the forearm with the hatching date. A similar analysis in females shows that both bill height and the timing of hatching were equally related to fitness; therefore, in this sex both bill height and the date of hatching were focal traits for selection.
