Greenfinch or House Sparrow?

These two get mixed up constantly. Here is what actually separates them, taken from each bird's own page.

Chloris chloris

A female greenfinch is dull enough to pass for a sparrow at a glance, but she still carries a bright yellow stripe along the edge of the closed wing and yellow in the tail. No sparrow has any yellow at all.
