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 Bialowieza 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 ...
