Breeding performance, mate fidelity, and nest site fidelity in a long-lived seabird: behaving against the current?

摘要: There is evidence that breeding failure associated with divorce and dispersal in many bird species. However, deviations from the general pattern "success-stay/failure-leave" seem to be common, suggesting factors other than performance may importantly influence mate habitat selection. Moreover, variability response suggests coexistence of different evolutionary strategies site selection within a population. In this study, we assessed how individuals conform success-stay/failure-leave kittiwakes (Rissa tridactyla), aimed identify categories presenting behavioural patterns. We considered individual attributes (experience, prior residence at nest site, multiple attempts), pair (arrival asynchrony, timing failure, duration), productivity patches. Timing was an important factor. Pair reunion probability close 0.5 failed pairs, but it consistently higher early late pairs. Prior better explained pairs duration. positive on perceptible only Divorce successful increased arrival first-time experienced breeders. Local positively influenced fidelity birds, not ones. Using memory models, found decisions integrate information temporal scale longer one year. This study contributed identification relevant states when addressing choice.
