| Description | Journal: Bird Study Capsule Predation is a major factor influencing the breeding success of Red-breasted Flycatchers under natural conditions. Aims To examine the breeding success of Red-breasted Flycatchers in relation to nest-site characteristics and time of breeding. Methods Data were collected during seven breeding seasons under natural conditions in Białowieża National Park. We used survival time analysis to estimate changes in survival probability over time and breeding success in relation to first-egg date and nest-site characteristics. Results Offspring fledged successfully from 51% of clutches, but the Kaplan–Meier estimate of survival was lower at 0.43. Of the unsuccessful clutches, 82% were lost to predators. The highest probability of loss was during egg-laying and in the second half of incubation. Breeding success was influenced by the height of the nest above the ground, but no relation to other nest-site characteristics was found. Conclusion To avoid predation Red-breasted Flycatchers build nests in various sites that are more open than most cavity-nesting species. The position of the nest-sites allows the sitting female to observe her surroundings and to escape rapidly from the nest, giving the chance for a replacement clutch. |
