Logrunners and Chowchillas: Orthonychidae

Physical Characteristics

The three species of this family of Passeriformes, or perching birds, are very similar in appearance. The largest, the chowchilla, is about 12 inches (30 centimeters) long. The two species of logrunners are only 7.3 to 8.4 inches (18.5 to 21 centimeters) long. They are stocky birds, with powerful legs and claws. Their specialized tails bear sharp spines on the stiff shafts of all ten tail feathers. This trait led this family of birds to also be called spine-tailed logrunners.

Male logrunners and chowchillas have white breasts, and females have reddish orange breasts. Chowchillas have unmarked black and white feathers. Logrunners, however, have patterns of brown, black, gray, white, and dull red.
