“…The White-eyed Vireo was the only species that demonstrated a shift from scrub/shrub at temperate stopover sites (Moore et al 1990, McCann et al 1993, Hopp et al 1995 to forest along the northern Yucatan coast (as seen in this study). The White-eyed Vireo generally occupies scrub and early secondary vegetation on its temperate breeding grounds and expands its habitat breadth to include scrub, secondary vegetation, mangrove, and forest throughout its tropical winter range (Ramos and Warner 1980, Rappole and Warner 1980, Lynch 1989, Greenberg 1992, Wunderle and Waide 1993, suggesting that the difference we observed between our site in northern Yucatan and temperate stopover sites may reflect a more general geographic shift in habitat use from temperate, breeding-type habitat to tropical, winter-type habitat.…”

Abstract. Animal habitat selection is a central focus of ecology and conservation biology. Understanding habitat associations in migratory animals is particularly complicated because individuals have variable habitat requirements during the annual cycle, across their geographic range, along migratory routes, and at multiple spatial scales. We studied habitat associations of 16 fall Nearctic-Neotropical migratory land birds at two spatial scales at a stopover site along the northern Yucatan coast to examine scale-dependent habitat use, identify proximate cues shaping birds' distributions, and evaluate similarities in habitat use between our tropical stopover site and temperate sites. We addressed scale-dependent habitat associations in two ways, by (1) quantifying species' distributions among and within broad vegetation types and (2) comparing migrants' associations with architectural gradients between the two spatial scales. We also evaluated the relative importance of vegetation architecture and floristics in explaining migrants' distributions within broad coastal vegetation types.Bird species were nonrandomly distributed among broad-and fine-scale vegetation types, and patterns of habitat use varied between the two scales. Moreover, birds had different preferences for vegetation architecture at the two scales, which may reflect trade-offs between competing demands and/or reduced variation in vegetation at the small scale in our study. These findings illustrate the manner in which spatial scale and range of vegetation variation influence perceptions of animal-habitat associations. Within broad coastal vegetation types birds refined their distributions in relation to architectural and floristic attributes, which provided them with redundant and/or complementary information regarding the distribution of suitable habitat. We suggest that the relative importance of architecture and floristics is likely scale-dependent. Habitat use at our site was similar to that observed at temperate stopover sites for almost all species, indicating that habitat affinities are maintained along the migratory route for these eastern populations despite latitudinal changes in environmental factors. We highlight examples of similar patterns observed in other migratory and nonmigratory animals to illustrate the generality of these patterns beyond en route land birds and our tropical site. We also indicate where we expect to see differences and outline areas of research that merit greater attention in order to advance our understanding of animal habitat selection.

“…However, we do not yet know whether the lack of a response to disturbance is restricted to white-eyed vireos or whether other military activities such as live fire could have a significant impact on energy expenditure. This species is expected to be resistant to human disturbance because it can breed in urban environments (Hopp et al 1995). It is therefore still unclear whether there is a cost of human disturbance in endangered species such as the related black-capped vireo.…”

“…Its winter range extends from Virginia to Honduras and parts of the Caribbean (Hopp et al 1995 (b) Heart rate transmitter placement, heart rate recording and activity monitoring We captured 14 white-eyed vireo males 2-3 hours before roosting (approximately 17.00 hours) by luring them into mist-nets using song playbacks. Of the 14 males monitored, only two were unpaired and the remaining were nest-building (nZ2), incubating (nZ2) or feeding nestlings (nZ1) or fledged young (nZ5).…”

No energetic cost of anthropogenic disturbance in a songbird

Anthropogenic or natural disturbances can have a significant impact on wild animals. Therefore, understanding when, how and what type of human and natural events disturb animals is a central problem in wildlife conservation. However, it can be difficult to identify which particular environmental stressor affects an individual most. We use heart rate telemetry to quantify the energy expenditure associated with different types of human-mediated and natural disturbances in a breeding passerine, the white-eyed vireo (Vireo griseus). We fitted 0.5 g heart rate transmitters to 14 male vireos and continuously recorded heart rate and activity for two days and three nights on a military installation. We calibrated heart rate to energy expenditure for five additional males using an open-flow, push-through respirometry system showing that heart rate predicted 74 per cent of energy expenditure. We conducted standardized disturbance trials in the field to experimentally simulate a natural stressor (predator presence) and two anthropogenic stressors. Although birds initially showed behavioural and heart rate reactions to some disturbances, we could not detect an overall increase in energy expenditure during 1-or 4-hours disturbances. Similarly, overall activity rates were unaltered between control and experimental periods, and birds continued to perform parental duties despite the experimental disturbances. We suggest that vireos quickly determined that disturbances were non-threatening and thus showed no (costly) physiological response. We hypothesize that the lack of a significant response to disturbance in vireos is adaptive and may be representative of animals with fast life histories (e.g. short lifespan, high reproductive output) so as to maximize energy allocation to reproduction. Conversely, we predict that energetic cost of human-mediated disturbances will be significant in slow-living animals.

“…It is possible females spent more time than males attending to nests and young. Although both sexes build nests, incubate eggs, and brood and feed young24, no data on time budgets is available.…”

“…We expected extra-pair paternity to be rare because breeding is asynchronous21 due to frequent nest failure and subsequent re-nesting2223, and a high level of paternal care2425. We chose white-eyed vireos for our study because much is known about their breeding biology24, nests are accessible within 2 m of the ground, adults can be captured and marked, and microsatellite markers were available for assessing parentage26. Our objective was not to test many predictor variables (e.g., vegetation) to determine which might be associated with patch fidelity.…”

Determining where organisms breed and understanding why they breed in particular locations are fundamental biological questions with conservation implications. Breeding-site fidelity is common in migratory, territorial songbirds and is typically thought to occur following reproductive success with a social mate and success of nearby conspecifics. It is currently unknown if frequency of extra-pair paternity in a population influences use of information about reproductive success of nearby conspecifics for site fidelity decisions. We investigated patch fidelity of white-eyed vireos (Vireo griseus) based on reproductive success and quantified frequency of extra-pair paternity. We found support only for females making patch fidelity decisions following reproductive success with a social mate. Patch fidelity of males was not associated with reproductive success of nearby conspecifics, suggesting males may not use this information when extra-pair paternity is infrequent or the association is non-existent in this species.
