What specialized foot adaptation is characteristic of Order Passeriformes?

Answer

Three toes pointing forward and one toe pointing backward for perching

Placement in the Order Passeriformes, often called perching birds, indicates a specific adaptation in the feet designed to securely grasp branches. This configuration consists typically of three digits oriented anteriorly (forward) and one digit oriented posteriorly (backward). This arrangement allows the bird to maintain a firm grip on a perch, even while resting or sleeping, which is a shared trait between the Kingbird and other songbirds.
