Female choice selects for extreme tail length in a widowbird.
Studied female choice in relation to male tail length in the long-tailed widowbird. Findings indicate that males whose tails were experimentally elongated showed higher mating success than males having normal or reduced tails. The possibility that intrasexual competition among males maintains the long tail was not supported: Males with shortened tails held their territories as long as did ...
Female choice selects for extreme tail length in a widowbird
(B) In the long-tailed widowbird (Euplectes progne) in Africa, such an experiment was actually carried out by Malte Andersson (1982), who experimentally manipulated tail length by cutting and ...
Long-tailed widowbird
Andersson experiment. Malte Andersson and colleagues tested Darwin's (and Fisher's) theory of female preference for ornamentation as the cause of extreme elongation of the male long-tailed widowbird's tail. They changed the length of males' tails and studied their relative mating success. Early in the breeding season, the territories of thirty ...

Andersson, Malte; Abstract. Darwin's 1 hypothesis that male secondary sexual ornaments evolve through female preferences is theoretically plausible 2-7, but there is little experimental field evidence that such preferences exist 8-10.

Female choice selects for extreme tail length in a widowbird
It is reported here that males in which the tail was experimentally elongated showed higher mating success than males having normal or reduced tails: males with shortened tails held their territories as long as did other males. Darwin's1 hypothesis that male secondary sexual ornaments evolve through female preferences is theoretically plausible2-7, but there is little experimental field ...
Experimental evidence for female choice and energetic costs of male
However, whereas female choice of both normally and supernormally elongated tails are confirmed by selection analyses (Andersson 1989;) as well as experiments (Andersson 1982(Andersson , 1992 ...
