Passerida
Passerida is, under the Sibley-Ahlquist taxonomy, one of two parvorders contained within the suborder Passeri (standard taxonomic practice would place them at the rank of infraorder). While more recent research suggests that its sister parvorder, Corvida, is not a monophyletic grouping, the Passerida as a distinct clade are widely accepted. Systematics and phylogeny The Passerida quite certainly consist of the 3 ''major'' subclades outlined by Sibley & Ahlquist (1990). However, their content has been much revised. In addition, it has turned out that not all passeridan lineages neatly fit into this arrangement. The kinglets are so distinct that they might actually form a separate infraorder, as they are only slightly less basal than the Corvoidea or the Picathartidae. See Jønsson & Fjeldså (2006) for details on phylogeny. Superfamily Sylvioidea Mostly smallish insectivores, distribution centered on the Indo-Pacific region.
