Fig. 3From: Offspring thermal demands and parental brooding efficiency differ for precocial birds living in contrasting climatesThe probability of being brooded—in relation to species, ambient temperature, and the time of day. The points show the probability of Red-wattled lapwing chicks (yellow) and Northern lapwing chicks (blue) being brooded during nighttime (a) and during daytime; (b) in relation to the ambient temperature. c presents the diel pattern of brooding. The curves with a shaded area indicate a model prediction with a 95% credible interval [49]. Variance components were estimated by the ‘glmer’ function for binomial errors with the logit link function [46]Back to article page
