Near passerine or higher land-bird assemblage are terms often given to arboreal birds or those most often believed to be related to the true passerines (order Passeriformes) due to ecological similarities; the group corresponds to some extent with the Anomalogonatae of Garrod[1] All near passerines are land birds. Whether all of these orders represent relatives of the Passeriformes is uncertain, but not well-supported by more recent data; however the bulk of evidence supports the hypothesis that most do indeed form a clade that also includes the Passeriformes. In addition, it is now becoming increasingly clear that "near passerines" and "higher landbirds" are not synonymous, but that the former is more probably a subclade of the latter, and that the latter also includes groups like Falconiformes
The near passerines traditionally comprise the following orders (with common names of some families in the orders):
Of these, the relationship of the Strigiformes is uncertain, whereas the first three groups almost certainly do not belong here; sandgrouse (Pterocliformes) may not even be higher landbirds. The Cuculiformes, Piciformes, Coraciiformes (including hornbills) and Trogoniformes seem to be very close to the Passeriformes on the other hand (Johansson & Ericson 2003), and one of these almost certainly is—among the living birds—the sister taxon of the Passeriformes.
