LACK OF ASSORTATIVE MATING FOR TAIL, BODY SIZE, OR CONDITION IN THE ELABORATE MONOMORPHIC TURQUOISE-BROWED MOTMOT (EUMOMOTA SUPERCILIOSA).

The article discusses the results of a study which examined whether mutual sexual selection maintains the Turquoise-browed Motmot's elaborate tail plumage. The study showed that the assortative mating measured within all pairs of the study population does not support the mutual sexual selection hypothesis that the tail is sexually selected in males only and that the natural selection accounts for the evolutionary maintenance of the elaborate female tail.
