Female Lance-tailed Manakins Choose Mates Carefully
Because of their lek mating system, the breeding season for male Lance-tailed Manakins means two things: courtship and copulation. That means that females are free to make mate choices that are unrestricted by concerns of parental care or access to specific territories, and they can be quite decisive. According to Lance-tailed Manakin ecologist Dr. Emily DuVal, up to 42 percent of females are frequently faithful to the same male if they attempt multiple nests in the same year. Dr. DuVal's team has even recorded one female whose chicks were sired by the same male for seven consecutive years!
