-
Because vocalizations in suboscines are assumed to be inherited characters, not learned, they have been used frequently in assessing species limits and providing clues to genetic discontinuities among suboscine populations.
-

-
The ability of territorial oscine males to discriminate between songs of neighbors and strangers has received considerable attention, but this phenomenon is virtually unstudied in suboscines.

All of these suboscines - both Old World and New - thus have geographical distributions that point back to Gondwana, and their beginnings there make even more sense once their close relatives, the songbirds, are taken into account.
-
Suboscines are particularly well represented, with vocalizations of more than 350 (!) species of ovenbirds, antbirds, tyrant flycatchers, and the like.
-
In addition, intrinsic individual variation, including learned cultural differences in oscines, provides the raw material for vocal divergence through drift or selection.

-
All extant European songbirds belong to the oscines, which are assumed to have arisen on the Australian continental plate.
-
Particularly among suboscines, subtle differences in songs often separate closely related species, as recently confirmed for thamnophilid antbirds.
-
In such trees the oscine songbirds were separated from suboscines, and they are usually the first avian branch (although the rest of the tree was virtually unchanged).
-
Blue-throated Hummingbirds show convergence with oscines in vocal complexity, song organization, song function, and possible learning of some song elements.

-
The Old World has only about 50 species of suboscines, and these fall into three small groups: the outrageously colorful, short-legged, plump pittas; the broadbills; and the asities.
-
Despite the predominance of suboscines in the Neotropics, our knowledge of bird song and its functions is biased heavily toward studies of oscines.
