Overview

Longitudinal cohort study reveals how predation target, age, and body condition shape flight initiation distance in common eiders, suggesting distinct plastic and selective mechanisms.

Key Points

To evaluate the relative importance of phenotypic plasticity and selective mechanisms in determining risk-taking propensity (flight initiation distance) among incubating common eiders exposed to differing predation pressures.
Analyzed a 12-year individual-based dataset from SW Finland in the Baltic Sea tracking female common eiders (Somateria mollissima).
Evaluated flight initiation distance across repeated measures (N_FID = 1009; N_individual = 559).
Tested within- and among-individual variation in relation to adult and nest predation risk, nest cover detectability, age, clutch size, and body condition.
Females exhibited behavioral plasticity by increasing flight initiation distance when adult predation risk was high, while risk-averse individuals were selectively enriched on islands with higher nest predation risk.
Risk-tolerant females chose nest sites with denser cover, aligning with personality-matching habitat selection.
Females plastically decreased flight initiation distances with advancing age, whereas better body condition correlated with increased risk-taking through selective mechanisms.
