Data from: Hidden leks in a migratory songbird: mating advantages for earlier and more attractive males

Lilian Manica, Jeff Graves, Jeffrey Podos & Regina Macedo
In some socially monogamous birds, territories sometimes occur in aggregations. The “hidden lek” hypothesis suggests that territorial aggregations might be explained by males establishing territories near successful males (“hotshot” model), or by females preferring to mate in large clusters (“female preference” model). In both scenarios, clusters would provide more opportunities for finding mates and achieving extra-pair copulations.
