Coraciimorphae

Coraciimorphae is a proposed suborder of birds that encompasses the Roller and Kingfisher families. This classification is based on molecular and morphological evidence, though its exact placement within the avian tree of life is still a subject of ongoing research and debate. Historically, these birds have been placed in different orders, such as Coraciiformes.

The birds within Coraciimorphae generally share certain characteristics. Many possess anisodactyl feet, meaning they have three toes pointing forward and one backward, which is adapted for perching. They are often brightly colored, with rollers exhibiting vibrant blues and greens, and kingfishers displaying a range of iridescent hues. Their diets are typically carnivorous, with many species specializing in insects, fish, or small vertebrates.

The distribution of Coraciimorphae is widespread, found in tropical and temperate regions across the globe. They inhabit diverse environments, from forests and woodlands to grasslands and coastal areas. Their nesting habits vary, with some building nests in tree cavities or burrows, while others are ground nesters.

The proposed monophyly of Coraciimorphae suggests a shared evolutionary history, differentiating them from other bird groups. While the term itself might not be universally adopted by all ornithological authorities, the underlying concept of grouping rollers and kingfishers together reflects recognized phylogenetic relationships. Further genetic and anatomical studies will continue to refine our understanding of this avian lineage.
