Success in sperm competition is an important determinant of male fitness mating systems with female multiple mating. Thus, risk represents a key dimension the social environment to which individual males are expected adaptively adjust their reproductive phenotype. Such adaptive phenotypic adjustment we here refer as niche conformance. In this pre-registered study, investigated how zebra finches, Taeniopygia guttata, behavior risk. We experimentally manipulated opportunity for extra-pair create two levels risk: 1) Single-pair, no risk; 2) Double-pair, compared courtship, mate guarding, copulation rates, and aggression between treatment groups. To identify hormonal correlates behavioral adjustment, measured plasma testosterone corticosterone before after started. Contrary our predictions, from Double-pair group decreased courtship rates those Single-pair group, responded less aggressively towards intruders than males. Testosterone over breeding cycle, but had effect on either or levels. Our results indicate that finches do not intensify competitive behaviors, upregulate hormones when another pair present. Although found evidence predicted responses risk, show plastically environment.

Abstract Random search theories predict that animals employ movement patterns optimize encounter rates with target resources. However, are not always able to achieve the best strategy. Energy depletion, for example, limits searchers’ activities, forcing them adjust their behaviors before and after encounters. Here, we quantified cost of mate in a termite, Reticulitermes speratus , revealed searching reduces selectivity mating partners. After dispersal flight, termites partner limited reserved energy. We found activity diffusiveness progressively declined over extended search. Our data-based simulations qualitatively confirmed reduced decreased efficiency. Also, prolonged periods colony foundation success number offspring. Thus, imposes doubled costs on termites. Finally, an partners, where males immediately paired any encountering females. dramatically changed behavior depending physiological conditions. finding highlights accounting internal states is essential fill gap between random empirical behavioral observations.
