Fig. 4From: Offspring thermal demands and parental brooding efficiency differ for precocial birds living in contrasting climatesa The boxplots summarise the median temperature during brooding after stabilisation (i.e. after the end of the 5th min) in relation to species: Red-wattled Lapwing (yellow) and Northern Lapwing (blue). The median temperature during brooding is depicted by the vertical line inside the box, its 95% confidence interval is depicted by the notch, and the 25–75% quantiles are depicted by a box. b The median temperature during brooding in relation to the ambient temperature for the Red-wattled lapwing (yellow) and for the Northern lapwing (blue). The curves with a shaded area indicate the model prediction with a 95% credible intervalBack to article page
