Ortega and colleagues (2017) discovered that, of ~3,400 Blue-footed Booby offspring, those with mismatched parents (one old and one young) had greater fitness. Either the mother or father could be older. Typically, both male and female Blue-footed Boobies select mates that have bright blue feet a sign of a high-quality diet. They are closely monitored because their population has been steadily declining as diet sources (sardines) declines and fewer boobies are mating. The mating behavior of Blue-footed Boobies can be best described as A. Assortative B. Random C. Both disassortative and assortative D. Disassortative.
