Interspecific Egg-dumping by a Violet-green Swallow in an Active Western Bluebird Nest (2007)
Danika Kleiber, Jenne Turner, Amber E. Budden, Janis L. Dickinson
Using molt limits to age Western Bluebirds (2005)
Daizaburo Shizuka, Janis L. Dickinson
Using data on the extent of prebasic molt in known-aged adult and first-winter Western Bluebirds (Sialia mexicana), we assessed the accuracy of the molt limit as a tool for ageing birds. Sixty-nine...
In cooperative breeders, the extent to which helpers at the nest adjust their contributions in accordance with direct and indirect (kin-selected) fitness payoffs remains an open question. In a...
Approximately 45% of western bluebird (Sialia mexicana) females have some chicks in the nest that are not sired by their social mates. Extrapair fertilizations account for 42% of...
SERIAL POLYANDRY AND ALLOPARENTING IN LONG-EARED OWLS (2002)
Jeffrey S. Marks, Janis L. Dickinson, Joseph Haydock
We used DNA fingerprinting to document serial polyandry in a double-brooded female Long-eared Owl (Asio otus) in western Montana. We also determined that an extra male that helped provision offspring...
Specialized Extrapair Mating Display in Western Bluebirds (2000)
Janis L. Dickinson, Ken Kraaijeveld, Femmie Smit-Kraaijeveld
Fitness consequences of helping behavior in the western bluebird (1996)
Dickinson, Janis L., Koenig, Walter D., Pitelka, Frank A.
We examined the fitness consequences of helping behavior in the western bluebird (Sialia mexicana) at Hastings Reservation in Carmel Valley, California, USA, and tested hypotheses for how helpers...
Trade-offs between postcopulatory riding and mate location in the blue milkweed beetle (1995)
In the blue milkweed beetle, Chrysochus cobaltinus (Coleoptera: Chrysomelidae), males remain stationary on females' backs for prolonged periods after a single, brief copulation. Lone males often...
Provisioning in western bluebirds is not related to offspring sex (1994)
Leonard, Marty L., Teather, Kevin L., Horn, Andrew G., Koenig, Walter D., Dickinson, Janis L.
Parents should invest more in one sex of offspring if the fitness return per unit investment is higher for that sex. Sex-biased provisioning may occur when sons and daughters differ in their needs or...
I examined the scramble competition mating system of the milkweed leaf beetle, Labidomera clivicollis(Coleoptera: Chrysomelidae), using data on lifetime mating success of two breeding cohorts in...
Winter resource wealth drives delayed dispersal and family-group living in western bluebirds
Dickinson, Janis L, McGowan, Andrew
Delayed dispersal, where offspring remain with parents beyond the usual period of dependence, is the typical route leading to formation of kin-based cooperative societies. The prevailing explanations...
Approximately 45% of western bluebird (Sialia mexicana) females have some chicks in the nest that are not sired by their social mates. Extrapair fertilizations account for 42% of offspring in these...
