Concordance ... between the two proxies was apparent when considering guard stage foraging trip durations ... but this was not as strong for the crèche foraging trips later in the season. Fledgling weights which are measured at the end ... of the breeding season were more strongly correlated with later foraging trips than with earlier trips. We ...
