Site Discrimination

The reproductive success of obligate brood parasitic birds depends on their ability to seek out heterospecific nests. Some nests are more suitable for parasitism than others and, for example, parasitic females may benefit from laying eggs preferentially and repeatedly at safer sites. Observations on patterns of Brown-headed Cowbird (Molothrus ater) parasitism on Eastern Phoebes (Sayornis phoebe) across 2 years suggested that parasitism occurred at above chance levels during the first rather than the second nesting attempts and at nests located under eaves rather than bridges. Previously parasitized nests were more likely to be parasitized again in the subsequent breeding season. Sites under eaves and bridges did not differ in whether Brown-headed Cowbirds could be detected in the proximity of the nest. However, nests from first nesting attempts and nests under eaves were less likely to be lost as a result of structural failure of the Eastern Phoebe's mud nest. These data suggest that site discrimination by Brown-headed Cowbirds leads to adaptive patterns of parasitism among available Eastern Phoebe nests.

Abstract We examined prevalence of extrapair young (EPY) between first and second broods of a multibrooded passerine, Eastern Phoebe (Sayornis phoebe). During the 1998–2000 field seasons, we conducted behavioral observations to assign social parentage to offspring in nests and then conducted paternity analysis on a subset of social families where (1) the male and female maintained their pair bond for all broods within the breeding season, and (2) adults successfully fledged their first brood and subsequently attempted a second brood within the same breeding season. We used three hypervariable microsatellite loci to document the presence and frequency of EPY in first and second brood offspring from 87 social family units where all individuals had been sampled (n = 174 broods, n = 81 social males, n = 82 social females, n = 769 offspring). Although the majority of pairs were both socially and genetically monogamous within a breeding season, 17.2% (15 of 87 families) of all families had EPY in at least one brood and we found two cases of intraspecific brood parasitism. Overall, 9.2% of all broods (16 of 174 broods) contained EPY and 5.1% of all nestlings that hatched were EPY (39 of 769 nestlings). Second broods were more likely to contain EPY than first broods (4.6% first broods with EPY [4 of 87], 13.8% second broods with EPY [12 of 87]). The total number of EPY was greater in second broods than in first broods (1.0% EPY [4 of 411 nestlings] in first broods, 9.8% EPY [35 of 358 nestlings] in second broods).
