What other bird families share the Order Piciformes with woodpeckers?

Answer

Toucans and barbets

The Order Piciformes represents a grouping of birds sharing a common ancestry and fundamental characteristics. While woodpeckers are the most dominant component of this order, the group also encompasses other distinct families. Specifically, toucans, which are well-known for their oversized and colorful bills, are classified within Piciformes. Additionally, barbets are also grouped under this order. This shared classification highlights that evolutionary relatedness in birds is not always based on the most obvious external features shared by all members, as toucans look significantly different from woodpeckers, yet they share a deep common ancestry reflected in skeletal structures and developmental traits.
