How to distinguish a male from a female goldfinch

Note the size of the bird. Males, though slightly larger than the females. This characteristic as a defining can only be seen if you compare two birds of approximately the same age, because birds, like people, can differ from each other in body structure and size.

Examine the amount of red stripes located under the bird's beak. This decoration have all the goldfinches, regardless of gender, but in males the width of the strips ranges from 8 to 10 mm, which is almost two times more than females.

Consider carefully the red stripes on the neck and feathers above the beak, try to determine whether the shade is cool or warm. The color of these feathers in the male cleaner, he practically scarlet. In females, this area may have cold crimson hue. This feature also may not be fundamental, because in many respects the color of the plumage depends on the conditions of food and living birds.

Examine the chest of a goldfinch. Males have brownish spots on the breast have distinct borders and more contrast to the white feathers of the chest. In females this transition less noticeable. But keep in mind that older females can sometimes be brighter than young males, so for comparison choose birds about the same age.

Listen to the bird. Females have a more high-sounding voice, as if they are talking to each other, but not sing. Males can output ringtones, different sound character and even mood. The downside of this sexing birds is something that recently caught the goldfinch a long time to remain silent.
