Effects Of Lek Location And Female Presence On Dancing Behavior In Long-Tailed Manakins (Chiroxiphia Linearis), June 2018, Dennis Finger

Sexual selection, the process by which individuals of one biological sex select mates of the other sex, often leads to the formation of displays, ornaments, and weapons to improve mating success. Long-tailed manakins (Chiroxiphia linearis) exhibit a unique example of sexual selection in their bright plumage, long tails, and coordinated lekking dances. I investigated sexual selection by analyzing dancing behavior of long-tailed manakins in Monteverde, Costa Rica. I filmed leks to measure the effects of dance variant (Cartwheel or Up-Down), lek location, and female presence on variation in dance features. Cartwheel bouts of dancing occurred only when the female was …

Animals use a variety of traits such as brightly colored plumage, nuptial gifts, chemical signaling, or intricate displays to attract mates. Long-tailed manakins (Chiroxiphia linearis) exhibit one of the more elaborate mating rituals found in the animal world. C. linearis form lek mating systems, where a group of males aggregate for cooperative courtship displays. They perform an alpha-beta duet that serves as a long-range cue to attract females to their perch zone for further display. Higher frequency matching in this duet has been correlated to higher courtship success. I investigated differences between alpha-beta vocalizations within and between leks, as well …
