In particular, their diversity may have been developed during the late Eocene/early Oligocene in the New Guinea archipelago, and then certain taxa pumped out into Asia and the rest of the world. Where they overlap, I consider the dates in Jønsson et al. However, Irestedt and Ohlson (2009) argued that the families in Barker et al.'s Callaeoidea (Melanocharitidae, Cnemophilidae, Callaeidae, and by implication, Notiomystidae) are really basal Passerida.
Corvida is the smaller branch, comprised of about 835 species.
Since there are many more species in Passerida, we place Corvida first.
The first contains the painted berrypeckers (Paramythiidae), shrike-babblers (Pteruthiidae, recently separated from the vireos), and the much bigger vireo family (Vireonidae). The others are Pachycare (Pardalotidae), Falcunculus (Falcunculidae), Oreoica and Aleadryas (Oreoicidae), Rhagologus (Rhagologidae), and Hylocitrea (Hypocoliidae). However, they treat it as monotypic, and I think that defining the tribe Oreoicini as consisting of Crested Bellbird is sufficient definition.
The second consists of the whistlers (Pachycephalidae) and orioles (Oriolidae). These two papers also disagree concerning the relationships of the familes in Orioloidea. (2015), using a dataset similar to Jønsson et al., gives an arrangement that is close to that of Aggerbeck et al. (2016) is somewhat different, removing Cinclosomatidae entirely to the root of Corvida and placing Eulacestomatidae basal in Orioloidea. This family of New Guinea endemics was previously removed from the Melanocharitidae (Passerida) and placed in their own family in Corvida.
Recently, Corvides (and Passerides) seem to be gaining ground following their use in H&M-4 (Dickinson and Christidis, 2014).
The actual membership of Corvida is a bit different from Cracraft et al.
However, the evidence for any of these is very weak. They appear to be fairly closely related, possibly congeneric, whether one looks at osteology (Olson, 1990) or DNA hybridization (Sibley and Ahlquist, 1987). (2016) estimated a common ancestor roughly 9-10 million years ago, so perhaps they are not quite so close after all. Next, there is small group of three families: whipbirds and wedgebills (Psophodidae), Australo-Papuan bellbirds (Oreoicidae), and shriketits (Falcunculidae). I accept the name Oreoicidae (Sibley and Ahlquist, 1985a) over Oreoicidae (Schodde and Christidis, 2014).
Regardless of whether they are placed in one genus or two, the Pipipi is basal, and the Whitehead and Yellowhead are sister to one another (Aidala et al., 2013). The main part of Orioloidea has two large branches. HBW treated them as a basal whistlers, along with 6 other taxa that have also been removed from the whistlers. Schodde and Christidis object that there is not a proper definition or description of Oreoicini Sibley and Ahlquist.
The first is the relation between the drongos (Dicruridae) and the fantail clade (Lamproliidae/Rhipiduridae). Like many Australasian birds, they are part of Corvida. (2011b) was the first genetic study to suggest any real affinities for Mohouoidea (sister to Campephagidae), although the support for this was weak. (2011b) were unable to place Mohouoidea reliably, Aggerbeck et al. (2016) found strong support for Mohouoidea as the basal clade in Corvida. (2016) placed them together with Neosittiodea, and sister to the Orioloidea/Malaconotoidea/Corvoidea clade. (2016) date each of these families as 23-25 million years old, while Moyle et al. Sibley and Monroe's Cinclosomatinae included two additional genera: Eupetes and Ifrita, while HBW-12's corresponding Eupetidae (del Hoyo et al., 2007) also includes Melampitta. al (2004) suggested that Melampitta belonged in the monarchs (Monarchidae), but with weak support.
It's clear enough that these are the basal taxa in Corvoidea, but in what order? The Mohouidae are New Zealand endemics that have previously been included in many different families. They and the mudnesters (Corcoracidae) were thought to form a clade. (2007) showed that the rail-babbler Eupetes was really related to Chaetops and Picathartes.
(2004) as some families have been moved eleswhere in the phylogeny.
