Table 1 Parameter estimates of the natal dispersal distance model based on 285 settlement events observed in Finnish white-tailed eagles. The response variable was natal dispersal distance (log-transformed). Explanatory variables fitted were sex (factor, ‘male’ or ‘female’), density around the natal nest in a 30 km radius (numeric, range 0–68), and year of expected recruitment (numeric, 1989–2022). Estimates, SE, χ2, df (Satterthwaite’s) and p-values of main fixed effects are shown. Natal territory ID and year of expected recruitment (categorical) were set as random effects in the model. All numeric predictors were scaled and statistically significant values are highlighted in bold
