- proper noun A taxonomic
familywithin the order Coraciiformes— the ground rollers.
from Wiktionary, Creative Commons Attribution/Share-Alike License
Many of the species belong to the endemic families or subfamilies Mesitornithidae, Brachypteraciidae, Philepittinae, Vangidae, Bernieridae, and Couinae.
It's superficially similar to true rollers (Coraciidae) and ground-rollers (Brachypteraciidae) but, unlike them, has semi-zygodactyl feet (though it has frequently very depicted inaccurately by artists who, in the absence of better information, have assumed that it's anisodactyl, like true rollers).
