What is a lek in terms of animal behavior?

A lek refers specifically to an arena where males gather to display their traits and engage in competitive behaviors to attract females. This behavior is common among certain species, particularly birds, where males showcase their plumage, vocalizations, or physical abilities to demonstrate fitness and genetic quality. The lek formation allows females to visit the area, observe potential mates, and select partners based on the displays they see, facilitating a form of sexual selection.

This behavior is distinct because it focuses on mating displays rather than direct competition for territory or resource acquisition, which could be expected in feeding areas or breeding grounds. Therefore, the emphasis on showcasing for female choice is what characterizes a lek, making it an essential concept in understanding animal behavior, particularly in species where mating strategies involve such social displays.
