From: Effects of age on foraging behavior in two closely related albatross species
Relationship between age and foraging behaviour for male (closed circles) and female (open circles) black-browed (BBA) and grey-headed (GHA) albatrosses during the incubation and brood-guard stages (a-c). Regression lines indicate the fitted values of the average of the most supported models for each response variable. Where a significant effect of sex was found, males (dotted) and females (solid) are shown with separate lines. Horizontal lines indicate no age effect but a significant sex effect. Values of transformed response variables (a and b) are back-transformed on the y-axis but the scale of the transformation is retained
