| Male grouse display lekking behavior, which is when many males come together in one area and put on displays to attract females. |
| Polyandry in lekking species may also occur if assessment criteria are subject to error, and in less well-understood situations. |
| Amazingly, from 5,000 to 50,000 males may congregate during lekking, which occurs over a long breeding season in some cichlids. |
| Males in many lekking species have conspicuous morphological ornaments that may be targets of female choice, but male contest competition may also be involved. |
| In a recent study, the size and weight of males captured either lekking or resting at the same time in the vicinity of leks were measured. |
| Hermits usually form leks and congregate on traditional lekking grounds, where females visit to choose a mate. |
