Ruff mating strategies
The ruff, Philomachus pugnax, is a sandpiper whose males congregate in communal display grounds or leks. Each male in the lek defends a mating court and competes for the attention of females. Some males, however, are exceptions to this rule, moving among and sharing the courts of other males. By rearing ruffs in captivity, Lank et al . ask whether these alternative mating strategies are the result of a simple genetic polymorphism, or subject to quantitative inheritance or environmental control.
