Table 2 Outcome of mixed effects models of trip duration, nest bout duration and nest attendance (proportion of time that at least one of the parents is present the nest)

From: Simultaneous GPS-tracking of parents reveals a similar parental investment within pairs, but no immediate co-adjustment on a trip-to-trip basis

  1. For trip duration and nest bout duration, a gamma distribution with log transformation was used, while for nest attendance, a beta regression with logit link function was used. The table presents the outcome of the full models. All models included bird ID and colony ID as random effects
