Male eastern bluebirds trade future ornamentation for current reproductive investment.
Life-history theory proposes that organisms must trade-off investment in current and future reproduction. Production of ornamental display is an important component of reproductive effort that has rarely been considered in tests of allocation trade-offs. Male eastern bluebirds (Sialia sialis) display brilliant ultraviolet-blue plumage that is correlated with mate acquisition and male competitiv...
متن کاملSex-biased parental investment is correlated with mate ornamentation in eastern bluebirds.
Males typically have greater variance in reproductive success than females, so mothers should benefit by producing sons under favorable conditions. Being paired with a better-than-average mate is one such favorable circumstance. High-quality fathers can improve conditions for their offspring by providing good genes, good resources, or both, so females paired to such males should invest preferen...
متن کاملFemale ornamentation influences male courtship investment in a lizard
*Correspondence: Devi Stuart-Fox, Zoology Department, The University of Melbourne, Building 147, Royal Parade, Parkville, VIC 3010, Australia e-mail: [email protected] Female signals of reproductive status often comprise both distinctive color patches and behaviors but their relative influence on male courtship investment is unclear. We examined the role of female-specific coloration in sign...
متن کاملContext-dependent development of sexual ornamentation: implications for a trade-off between current and future breeding efforts.
Allocation of resources into the development of sexual displays is determined by a trade-off between the competing demands of current reproduction and self-maintenance. When reproduction overlaps with acquisition of sexual ornamentation, such as in birds with a yearly post-breeding moult, such a trade-off can be expressed in elaboration of sexual traits used in subsequent matings. In turn, sele...
متن کاملA field test of female mate preference for male plumage coloration in eastern bluebirds.
A growing body of evidence shows that female birds use male plumage coloration as an important criterion in mate choice. In the field, however, males with brighter coloration may both compete better for high quality territories and be the object of female choice. Positive associations between territory quality, male-male competitive ability, and female preferences can make it difficult to deter...
