Polygamy in captivity - polygynous and polyandrous mating to facilitate the breeding strategy

In the wild, the male and the female shamas will both provide parental care, thus indicating that they are monogamous by nature. Perhaps, under certain circumstances, there may be occasions where a shama in the wild could have more than one mate within a breeding season, such as the losing of a mate to predators early in the breeding season. In captivity however, polygamy can be employed if the breeding strategy requires a single bird to be bred to more than one mate during a breeding season.

The polygynous mating system uses a single male to be mated successively to several females during the breeding season and the polyandrous mating system uses a single female to be mated successively to several males during the breeding season.

Below are the videos of two clutches resulting from polygynous mating, using a single male mated to two females successively. The male was removed from the aviary of the first female 2 days after she started incubation and placed with the second female. The first clutch started hatching on 22nd September and the second clutch on 30th September. Both females are now raising their respective clutches on their own without the male.

As part of the breeding plan, these two females, both still fresh from their annual molt, will be bred  to other males later on during this same breeding season. Hence they will be participating in both polygyny and polyandry within a single breeding season.
