How to tell a female and male society finch apart?

You have society finch and you cant tell if its a female or a male?

• Answer:

  Male and female society finches are identical in appearance, but not in behaviour - however, to discover whether yours is male or female (assuming you only have the one) you'll need to intoroduce it to another society finch known to be female. Males will conduct a distinctive courtship dance during which he will fluff up his feathers and bounce up and down on the perch, whereas females will not. There's a picture of a male (with the darker colouring of the wild bird rather than the light feathers that your domesticated bird may have) engaged in the dance at http://www.efinch.combirdpixchocpiedsoc.jpg
