Their comical nature makes them my most favorite of all the Australian finches, save the zebras. As they fly from perch to perch they bob their heads up and down upon landing. This gesture never stops from creating a laugh from anyone observing them. The Heck's has been touted as Australia's most elegant finch. Being slender and sleek with a smooth, sharp color pattern there is no reason to wonder why.
Beak color ranges from bright orange to deep red depending on the color mutation.
Heck's colors range from the normal as described below to cremes, whites, and fawns. The head of a normal is a beautiful soft gray with black streaks around the eyes giving it an almost oriental appearance. Below the beak and running down to the top of the chest is a bold black bib. The body itself is a soft grayish brown with almost a tinge of peach. The underparts of the Heck's is yet paler and the vent area is almost white.
