A pair of Zebra Finches, Taeniopygia guttata. Males and females are very similar in size, but are easily distinguished from one another as the males usually have bright orange cheek feathers, a red beak (as opposed to the orange beak of a female), and generally more striking black and white patterns. Textures added in Photoshop.
