Site Characteristics

Despite hundreds of studies, we know very little about the causes and fitness-related consequences of nest-site selection. For example, it is not typically known whether the rarely reported fitness consequences of site selection are the result of nest, individual, or nest-site variables or combinations of these factors. Reuse of previously constructed nest sites is a prevalent behavior in many animals and offers the opportunity to experimentally tease apart whether seasonal reproductive success is a function of nest, individual, or nest-site characteristics. I used observational and experimental data to test three hypotheses related to these factors in association with barn swallow ( Hirundo rustica L., 1758) nest reuse. While both nest and individual characteristics explain variation in seasonal reproductive success, nest location per se is not an important factor defining the outcome of nest-site selection. Whereas traits related to habitat and individual characteristics are likely confounded in correlational studies, my experiments demonstrate a causal relationship between seasonal reproductive success and aspects of the nest and individual, the latter explaining more variation in the model than nest characteristics. Knowledge of the relative roles of individual, nest, and nest-site attributes are important for understanding the causes and consequences of habitat selection behavior.

We investigated the extent of ecological segregation in the use of the food, space, and habitat resources of three sympatric species of the genus Buteo (red-tailed, ferruginous, and Swainson's hawks) coexisting in the prairie–parkland ecotone of southeastern Alberta. We concluded that food was not a resource for which the hawks were competing because the overlap in diets exceeded 80%, and because ferruginous hawks successfully fledged supernumerary broods and Swainson's hawks, broods of at least average size. Furthermore, there was no evidence that each species hunted prey at different times of the day or concentrated on different-sized prey. Each of the three species exhibited a dispersed distribution of nest sites which suggests competition for space; this pattern was not as evident when the distribution of nests among species was considered. Nevertheless, when pairs of different species nested in close proximity their reproductive success declined significantly, suggesting interspecific competion for space. The three species exhibited differences in nest site characteristics, suggesting that, although sympatric, they tended to segregate on the basis of habitat. Ferruginous hawks appear to inhabit arid and open landscapes, red-tailed hawks woodland habitat, and Swainson's hawks the interface.

Ornamental Traits

That ornamental traits of females can act as signals of quality has gained empirical support, but whether and how such ornaments of females mediate social interactions with conspecifics remains less clear. Female Tree Swallows (Tachycineta bicolor (Vieillot, 1808)) aggressively compete for and defend nest sites, and as such, nest site intrusions by conspecific females challenging ownership of a nest may prevent territory-owning females from dishonestly displaying ornamented plumage. We tested whether plumage brightness of female Tree Swallows influences nest site retention and reproductive success by experimentally enhancing or reducing their plumage brightness relative to controls prior to breeding. Females with reduced brightness were more likely to retain their nests sites and breed relative to control females and females with experimentally enhanced brightness. Females displaying enhanced brightness also tended to initiate clutches later than females with control and reduced brightness. Overall, lower nest site retention and reproductive success for females with enhanced brightness is consistent with social costs imposed on individuals dishonestly signalling high quality. Future studies in female birds should consider whether costs of losing a nest site to intruding conspecific females, especially in species where nest sites are limited, is a mechanism that maintains the honesty of signals of quality.

In this study, we investigated potential cues determining choice of mate by female Red-winged Blackbirds (Agelaius phoeniceus) by examining male and nest-site characteristics that (i) affect the reproductive success of females, (ii) can be assessed by females prior to mating, and (iii) vary among potential mates, in 1983–1985. The 17 characteristics considered reflected the accessibility of redwing nests to mammalian predators and to Marsh Wrens (Cistothorus palustris), the importance of cooperation between female redwings in nest defense, and the paternal quality (feeding and defense of nestlings), genetic quality, physical condition, and size of redwing males. Only 4 characteristics, distance to nearest wren nest, distance to nearest simultaneously active conspecific nest, height of vegetation supporting the nest, and nest defense effort of males, met all of the above criteria in at least 1 year. Of these, proximity to wren nests appeared to satisfy the requirements most consistently in time and space, and thus might be the most likely to affect female redwing choice of mate. However, experimental manipulations are needed to ascertain whether any of these characteristics are cues of female mate choice in Red-winged Blackbirds.

Nesting Material

Nest-site characteristics influence reproductive success in birds. Most studies of nest-site selection evaluate nest characteristics following the commencement of egg-laying, possibly overlooking the importance of pre-existing nest-site features that may be altered during the nesting process. Because Common Eiders ( Somateria mollissima (L.,1758)) often lay their eggs in nest bowls created in previous years, we were able to experimentally place moss or feather down in nest bowls prior to nesting. We then quantified whether these materials increased nest establishment or advanced laying dates relative to control nests and nests where material was removed prior to arrival of nesting females. We found no difference in the likelihood of successful nest establishment between groups. However, the onset of incubation occurred 2–3 days earlier in nest bowls that contained feather down versus nest bowls with little or no nesting material. Nest bowls containing feathers or vegetation may be selected first if they increase nest survival, perhaps by enhancing egg concealment during the critical early-laying period. The presence of material for egg concealment may be particularly important in nesting environments where tall or dense vegetation is not available to provide nest cover.

Abstract Determining how site characteristics influence reproductive success can help guide conservation planning for declining wildlife populations. For colonially breeding seabirds, nest survival and predation risk can be influenced by both colony and nest site characteristics such as colony size, nest density, and nest location. We evaluated the reproductive success of a declining population of Roseate Terns (Sterna dougallii) in the United States and British Virgin Islands to identify primary causes of nest failure and investigate the influence of colony and nest site covariates on nest survival. In addition, we measured the influence of colony characteristics on chick provisioning to determine if resource competition in larger colonies affected foraging rates. Monitoring was conducted in 2017–2018 via motion-triggered cameras, which enable 24-hr monitoring with minimal nest disturbance. Nest survival was defined by both hatch success and early chick success, defined as a chick surviving from hatching through the fourth post-hatch day. We monitored 118 nests in 6 colonies over the 2 breeding seasons. We found that predation was the primary cause of nest failure. Both hatch and nest success increased with colony size, and neither nest survival nor predation probability was influenced by individual nest site characteristics. Provisioning rates were comparable among colony sites and did not vary with colony size. Our results suggest that directing management efforts toward enhancing colony size, rather than focusing on nest site characteristics, can be beneficial for tropical seabird conservation.
