lekking

[dpaulson@ups.edu (Dennis Paulson)]

In response to Tony Canning's comments about lekking, there are also
mammals that do this: hammer-headed bat (Hypsignathus monstrosus) in west
Africa and kob and lechwe (antelopes of the genus Kobus) in east Africa. 
Quite a few birds, including a number of grouse (Phasianidae), a few
sandpipers (Scolopacidae), a few hummingbirds (Trochilidae), and many
manakins (Pipridae) perform impressive lek displays. I am unaware of any
reptiles that exhibit lek behavior. Very many frog species come together in
'choruses,' which conform to the definition of lekking in other
vertebrates.
