Siskin or Greenfinch: How To Tell The Difference?

Both the Eurasian Siskin and Greenfinch are extremely similar at first glance, so it's no surprise that it's a common question that we find people asking. In this short article, we'll highlight the main differences between the two different bird species to help you identify them easier.

The main differences between the two are that Siskins have a more streaked plumage with a distinct wing bar that goes across the wing, tails are more of sharper fork shape, and black bib - males also have a black cap. Female Siskins lack the black crown, so more often than not, they are more likely to be confused with greenfinches. Greenfinches also have a yellow stripe down the edges of the wings.

There are a few more differences, which we will go into a little more detail below. However, the above is generally the best and most obvious way to distinguish the two apart.

Other differences between the two species

Both are members of the finch family and have similar looking beaks - perfect for eating seeds. However, the Siskin has a slightly more delicate looking bill when compared to the more 'heavy' looking bill of the Greenfinch. When it comes down to size, the Greenfinch is slightly the larger of the two as well.

The bill of a Siskin appears more of a sharper shape, with the Greenfinch having more of a conical shaped bill.
