This tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.close box
Sibley and Ahlquist (1990) divided the oscines into two clades they called Corvida and Passerida. While Passerida has been confirmed (with some slight changes of membership), Barker et al. (2002) showed that Corvida was not a clade but a grade, as shown in the tree above. Thus Corvida, as a group, does not really exist.
Sibley and Ahlquist’s (1990) Menuroidea included Menuridae (lyrebirds), Atrichornithidae (scrub-birds), Climacteridae (Australasian treecreepers), and Ptilonorhynchidae (bowerbirds). More recent studies show that the latter two are sister taxa and are more closely related to other oscines than to Menuridae (Barker et al. 2002, 2004; Ericson et al. 2002a; Beresford et al. 2005; but see Ericson et al. 2002b). There are so far no sequence data available for Atrichornithidae, and it has been retained here within a reduced Menuroidea (Sibley and Ahlquist 1990). The unnamed group including Climacteridae and Ptilonorhynchidae is sister to all oscines other than Menuroidea (Barker et al. 2002, 2004; Ericson et al. 2002b; Beresford et al. 2005; but see Ericson et al. 2002b).
Meliphagoidea consists of Maluridae (fairy wrens), Meliphagidae (Honeyeaters), Pardalotidae (pardalotes), Acanthizidae (scrub-birds, thornbills), and Dasyornis (bristleheads) (Cracraft and Feinstein 2000; Barker et al. 2002, 2004) and is sister to the remaining oscines (Barker et al. 2002, 2004; Beresford et al. 2005). Relationships within Meliphagidae and Acanthizidae have been investigated by Driskell and Christidis (2004). Two more families, Pomatostomidae (Australian babblers) and Orthonychidae (logrunners) are successively more closely related to Corvoidea and Passerida (Barker et al. 2002, 2004).
Three more clades form a polytomy with Corvoidea and Passerida: Callaeatidae (New Zealand wattlebirds), Cnemophilinae (traditionally supposed to be birds of paradise, belonging to the corvoid Paradiseidae), and Melanocharitidae (most berrypeckers — one genus, Paramythia, is corvoid) (Cracraft and Feinstein 2000; Barker et al. 2002, 2004; Beresford et al. 2005).
