The society finch is a small, social, domestic bird that is not found in the wild. Visual identification of male (cock) and female (hen) society finches is difficult since the colouring is the same in both sexes. Birds of each sex have similar colour variations, according to the Doctors Foster and Smith Pet Education website. Society finches are most commonly brown and white or cream and white. Other colouring may include fawn and white or chocolate, black, grey and chestnut with white areas. Determining the differences between male and female society finches comes down to song and behaviour.
Find either a pet store that sells society finches or a society finch owner.
Observe the singing behaviour of the society finches, paying special attention to those that sing and those that do not sing. The male of the species has a squeaky song during mating, according to the Finch Information Center. Females typically do not sing. However, when a female society finch does sing, there is a distinctive difference usually only picked up by an experienced individual. According to eFinch.com, the differences are hard to describe. Both male and females do make chirping sounds.
Observe the body behaviour of society finches. According to eFinch, a male society finch approaches a female, as part of the mating behaviour, with an upstretched neck and fluffed feathers, singing his song and bounces back and forth on the perch.
