Fig. 3From: Shadowed by scale: subtle behavioral niche partitioning in two sympatric, tropical breeding albatross speciesScatterplot of bill morphometrics indicates clustering in morphological space. Morphometrics cluster by species (shorter, thicker bills in black-footed albatrosses (BFAL)) and by sex within species (female bills generally shorter and less deep). Bill measurements between the sexes overlap more in black-footed albatrosses than they do in Laysan albatrosses (LAAL)Back to article page
