LEKS is a term commonly used in the field of animal behavior, specifically in reference to the behaviors of certain bird species. It is defined as an arena or display site where males of certain bird species congregate and perform elaborate courtship displays to attract females. The term was first introduced by Niko Tinbergen, a renowned ethologist, to describe the unique mating behavior observed in some species of birds.
LEKS are often located in open areas with good visibility, such as meadows or open grasslands. They serve as gathering places where males of the same species display their fitness and attractiveness to potential mates. The courtship displays performed within LEKS can involve a combination of vocalizations, colorful plumage displays, intricate dances, or aerial acrobatics.
These displays are observed as a competition among males to gain the attention and favor of females. Females visit LEKS and observe the displays before selecting a mate. The males' ability to perform these elaborate displays effectively reflects their genetic fitness, health, and overall quality as potential mates.
LEKS provide a platform for significant social interaction and competitive behavior among males, with the primary goal of successfully attracting mates. They are particularly common among certain bird species, such as grouse, peafowls, and birds-of-paradise.
Overall, a lek can be defined as a specific area where male birds display their courtship behaviors to attract females, creating an arena for mating competition and selection.
