Possible Role Of Breeding Phenology, Brood Size, And Male Parental Care On The Number Of Nesting Attempts By Female Eastern Bluebirds, A Facultatively Multibrooded Species, Michael Daniel Patton

Online Theses and Dissertations

To maximize reproductive output, several species of songbirds attempt to raise two or more broods in a single breeding season. The results of previous studies have revealed much variation among species in the factors that influence the likelihood of female songbirds attempting to raise multiple broods during a breeding season. As such, additional studies are needed to better understand the roles of early breeding, brood sizes, and, especially, male parental care in determining the likelihood of having multiple broods. My objective, therefore, was to examine the possible effects of breeding initiation date, brood size, and male provisioning behavior on the …
