individual attributes and parameters for PCA

One row per individual per date, with individual attributes and PCA parameters. Ring column contains a unique ID for each individual bird. dist_to_terr contains the distance in metres between the feeding station and the nest box used by the bird in the subsequent spring breeding season. visits_by_others contains the number of visits by other tagged individuals (great tits and blue tits) at the same site on the same date. The final six columns are the parameters used in the principal component analysis (PCA). Bout lengths and bout intervals are in seconds.
