Corvidiformes

Corvidiformes is an order of birds that includes the families Corvidae, which are the crows, ravens, rooks, jackdaws, jays, magpies, and nutcrackers, and sometimes also the Old World suboscine passerine family Eurylaimidae, the broadbills, and the New World suboscine passerine family Pittidae, the pittas. However, the placement of these latter two families within Corvidiformes is not universally accepted, and they are often placed in their own orders, Eurylaimiformes and Pittiformes, respectively.

The Corvidae family is the largest family of passerine birds, with over 120 species. These birds are found in all continents except Antarctica. They are known for their intelligence, complex social behavior, and problem-solving abilities. Many corvids are omnivorous, feeding on a variety of insects, small vertebrates, seeds, and fruits. They are also known for their vocalizations, which can be quite varied and complex.

The broadbills and pittas are also passerine birds, but they are found only in tropical regions of Africa, Asia, and Australia. They are generally more colorful than corvids and have more specialized diets, often feeding on insects. Their classification within Corvidiformes is based on some shared morphological and behavioral characteristics, but genetic studies have sometimes placed them in different evolutionary lineages.

The order Corvidiformes is characterized by a generally large size among passerine birds, strong feet with anisodactyl arrangement of toes, and a strong, usually slightly hooked bill. Many species exhibit highly developed vocalizations and a capacity for learning and mimicry. Their intelligence is a subject of significant scientific interest, with studies demonstrating advanced cognitive abilities in species like crows and ravens.
