The 46 Orders










Corvida Wagler, 1830

At this point the passerines divide into two branches, the Corvida and Passerida. Corvida is the smaller branch, comprised of about 835 species. Since there are many more species in Passerida, we place Corvida first. The use of “Corvida” for the clade sister to Passerida follows the logical terminology of Cracraft et al. (2004), although the term Corvoidea, or even “core Corvoidea” is in common use. 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. (2004) as some families have been moved eleswhere in the phylogeny.

Current thinking is that the Corvida have their origin in Australia/New Guinea (the actual continent of Australia). 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. I particularly commend to your attention the discussion in Jønsson et al. (2011b) and secondarily in Aggerbeck et al. (2014). Where they overlap, I consider the dates in Jønsson et al. (2016) more reasonable.

Recent Taxonomic Developments

The taxonomy in Barker et al. (2004) suggested Corvida is divided into two superfamilies, Callaeoidea and Corvoidea. However, Irestedt and Ohlson (2009) argue that the families in Barker et al.'s Callaeoidea (Melanocharitidae, Cnemophilidae, Callaeidae, and by implication, Notiomystidae) are really basal Passerida. They show that if the analysis is done without the RAG-1 gene, these families end up in Passerida. Apparently RAG-1 has a strong signal that overwhelms conflicting evidence from other genes. Since the RAG-1 signal is not supported by other genes, they argue it is spurious. Although there is room for dispute here, I found Irestedt and Ohlson's argument sufficiently convincing to follow it here. More recent analyses such as Aggerbeck et al. (2014) and Jønsson et al. (2011b) also support removing these taxa from Corvida.

In late 2013 I restructured the Corvida based on Aggerbeck et al. (2014). They examined up to 22 nuclear loci, and were able to create a generally well-supported phylogeny for Corvida. However, the thin taxon sampling means that some of that support may be less than it seems. Previously, the most comprehensive study of the Corvida was the six-gene analysis by Jønsson et al. (2011b), which includes one of more representative from each of the corvid families except the monotypic Pityriaseidae (bristlehead). Most of the well-supported portions of Jønsson et al.'s (2011b) phylogeny are pretty much the same as Aggerbeck et al. However, Aggerbeck et al. were able to find good support for much more of their phylogeny.

Another restructing came in December 2015 following the publications by Marki et al. (2015) and Jønsson et al. (2016). These two papers, with 5 overlapping co-authors both use a similar data set. Marki et al. used up to 7 nuclear and 4 mitochondrial genes, while Jønsson et al. added an eighth nuclear gene (fib5). Indeed, Jønsson et al. sampled a large fraction (86%) of the corvid taxa, far beyond what anyone else has done. In comparison, Aggerbeck et al. (2014) only covered about 5% of the corvids. I have ended up with a tree that is a compromise between Aggerbeck et al. (2014) and Jønsson et al (2016). The tree in Marki et al. (2015) will get limited use here as it is only sparsely labeled.

The following table details the differences between the Aggerbeck et al. (2014) and Jønsson et al. (2016) trees. Aggerbeck et al. did not consider Pteruthiidae and Lamproliidae to be separate families, and so did not include them in their analysis. In the table below, Pteruthiidae is considered part of Vireonidae and Lamproliidae part of Rhipiduridae.

Taxon Aggerbeck et al. Jønsson et al.
Neosittidae Sister to Eulacestomaidae Sister to Malaconotoidea
Oriolidae Sister to Paramythiidae-Vireonidae clade Sister to Pachycephalidae
Psophodidae Sister to Vireonidae Sister to Oreoicidae
Machaerirhynchidae Sister to Aegithinidae-Vangidae clade Sister to Rhagologidae
Rhipiduridae Basal in Corvoidea Basal, but sister to Dicruridae
Monarchaidae Sister to Laniidae/Corvidae Sister to Ifritidae

Both Aggerbeck et al. and Jønsson et al. agree that the Mouhouidae are basal in Corvida, and that the rest of Corvida consists of three clades, here called Orioloidea, Malaconotoidea, and Corvoidea. Except for the sittellas (Neosittidae), they also agree on the composition of the clades, but not on the internal structure.

What to do about it? For starters, I'm putting the sittella family Neosittidae in its own superfamily (Neosittoidea). This group seems to be on a long branch, and I suspect its various placements reflect that. I don't think we have reliable information about it yet. The use of a separate superfamily is meant to indicate that, moreso when I put it after Orioloidea.

The next two problem taxa are the orioles (Oriolidae) and whipbirds (Psophodidae). Interestingly enough, Marki et al. (2015) have an arrangement similar to Aggerbeck et al., even though their dataset seems to be an earlier version of the Jønsson et al. dataset, missing one gene. Somehow, Jønsson et al. still get strong support for Oriolidae and Pachycephalidae as sister taxa. I'm not happy with any solution here, but will stick with the Aggerbeck/Marki version.

Turning to Malaconotoidea, the boatbills (Machaerirhynchidae) are the next disagreement point. I don't have a strong reason to chose one or the other, just a hunch. I leave them sister to the Aegithinidae-Vangidae clade.

This brings us to Corvoidea. The first issue is the relation between the drongos (Dicruridae) and the fantail clade (Lamproliidae/Rhipiduridae). It's clear enough that these are the basal taxa in Corvoidea, but in what order? Aggerbeck et al. (2014) tell us that the fantails are basal. Marki et al. (2015) have the drongos basal. Finally, Jønsson et al. (2016) consider them sisters. Given the ambiguity (and short internodes), I'm treating them as equally basal, listing the drongos first as the smaller group.

That leaves the monarchs. These too are troublesome, with three papers giving three different answers. Aggerbeck et al. put them in a clade with the birds-of-paradise (Paradisaeidae). Marki et al. have them sisters to the jays and crows (Corvidae). Finally, J&soslash;nsson et al. put them sister to a shrike/crow clade. I'm inclined to think the shrikes and crows go together, and have put the monarchs on their own branch, between the bird-of-paradise and crow clades.

The TiF Corvida Tree

Aggerbeck et al. describe their results as a basal group (Mohouidae) plus three major clades. Jønsson et al. (2016) found the same four clades, disagreeing on which clade the Neosittidae belong to. As mentioned above, the TiF list also treates Neosittidae as a superfamily, Neosittoidea. The other four clades are listed as Mohouoidea, Orioloidea, Malaconotoidea, and Corvoidea. Each of these clades is well-supported in Aggerbeck et al. (2014) and Jønsson et al. (2016). Jønsson et al. date each clade to the mid-Oligocene, roughly 28 million years ago (I think the dates in Aggerbeck et al. are too old.) Except for the addition of the cuckooshrikes to Malaconotoidea, the composition of Malaconotoidea and Corvoidea is essentially the same as in Cracraft et al. (2004). Recent studies have not had much effect on this.

The phylogeny currently used by TiF is given in the tree below.

Corvida tree

Mohouoidea Matthews, 1946

Mohouidae: Whitehead & allies Matthews, 1946

2 genera, 3 species Not HBW Family

The Mohouidae are New Zealand endemics that have previously been included in many different families. Writing in HBW-13, Boles (2007) mentions Paridae, Timaliidae, Orthonychidae, Campephagidae, Sylviidae, Maluridae, and Acanthizidae (=Pardalotidae). The Acanthizidae option was followed by Sibley and Monroe (1990), Dickinson et al. (2003) and version 2.0 of the IOC checklist (Jan 2009). Boles (2007) and HBW include them in Pachycephalidae. However, the evidence for any of these is very weak.

Jønsson et al. (2011b) was the first genetic study to suggest any real affinities for them (sister to Campephagidae), although the support for this was weak. Although Jønsson et al. (2011b) were unable to place Mohouidae reliably, Aggerbeck et al. (2014) and Jønsson et al. (2016) found strong support for Mohouidae as the basal clade in Corvida.

Boles merges Finschia into Mohoua. They appear to be fairly closely related, possibly congeneric, whether one looks at osteology (Olson, 1990) or DNA hybridization (Sibley and Ahlquist, 1987). However, Jønsson et al. (2016) estimated a common ancestor roughly 9-10 million years ago, so perhaps they are not quite so close after all. 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).

Orioloidea Vigors, 1825

Click for Orioloidea genus tree
Click for Orioloidea
genus tree

Orioloidea is our first large grouping in Corvida. It has two parts. The first seems to include three small families: Australo-Papuan bellbirds (Oreoicidae), shriketits (Falcunculidae), and quail-thrushes and jewel-babblers (Cinclosomatidae), together with one large family, the whistlers (Pachycephalidae). The second part includes the monotypic ploughbill family (Eulacestomatidae), the orioles (Oriolidae), the two painted berrypeckers (Paramythiidae), whipbirds and wedgebills (Psophodidae), shrike-babblers (Pteruthiidae, recently separated from the vireos) as well as the much bigger vireo family (Vireonidae).

There is disagreement about whether the sittellas (Neosittidae) belong here, with Aggerbeck et al. (2014) in favor and Jønsson et al. (2016) against. These two papers also disagree concerning the relationships of the familes in Orioloidea. Marki et al. (2015), using a dataset similar to Jønsson et al., gives an arrangement that is close to that of Aggerbeck et al., so I have followed the last except for the removal of the sittellas.

Oreoicidae: Australo-Papuan Bellbirds Sibley & Ahlquist, 1985

3 genera, 3 species Not HBW Family (HBW-12:411, 435)

Oreoicidae genus tree
Oreoicidae genus tree

The small Australo-Papuan family Oreoicidae is the first of three small families: Oreoicidae, Falcunculidae, and Cinclosomatidae. Divisions between them are fairly deep, dating to near the Oligocene/Miocene boundary. Jønsson et al. (2016) estimate a common ancestor for the three families in the late Oligocene at about 26 million years. Although the grouping of Falcunculidae and Cinclosomatidae was strongly supported in Aggerbeck et al. (2014) and Jønsson et al. (2016), support for including Oreoicidae was less strong. Jønsson et al. include Psophodidae in this clade, but this is only weekly supported. Both Aggerbeck et al. (2014) and Marki et al. (2015) put Psophodidae near the vireos even though the Marki et al. dataset is quite similar to the Jønsson et al. dataset.

Jønsson et al. (2016) found the three Oreoicidae species to form a strongly-supported group. They even suggest putting them all in the same genus (Oreoica has priority), but with the split between them somewhere around 10 million years ago, I do not see a compelling reason to do this.

Although both Aggerbeck et al. (2014) and Jønsson et al. (2016) both place Oreoicidae near Falcunculidae and Cinclosomatidae, earlier analyses based on fewer genes have come to different conclusions. Norman et al. (2009a) weakly supported placing Aleadryas and Oreoica in Malaconotoidea while Jønsson et al. (2008a) put Aleadryas and the former Pitohui, Ornorectes, near Campehagidae.

I accept the name Oreoicidae (Sibley and Ahlquist, 1985a) over Oreoicidae (Schodde and Christidis, 2014). Schodde and Christidis object that there is not a proper definition or description of Oreoicini Sibley and Ahlquist. However, they treat it as monotypic, and I think that defining the tribe Oreoicini as consisting of Crested Bellbird is sufficient definition.

Falcunculidae: Shriketits Chenu and des Murs, 1853

1 genus, 3 species Not HBW Family (HBW-12:409)

The Falcunculidae are sister to the Cinclosomatidae. I keep them in two families because the division between them is deep (about 22 mya), and because they are quite different. There doesn't seem to be strong evidence for regarding the Falcunculidae as one species instead of three. I have a hunch the lineages are older than many think, so I treat them as three species.

Cinclosomatidae: Quail-thrushes and Jewel-babblers Matthews, 1921-2

2 genera, 12 species HBW-12 in Eupetidae (pp. 365-8)

Cinclosomatidae species tree
Cinclosomatidae species tree

Toon et al. (2012) examined DNA from a number of Quail-thrushes. The arrangement of Cinclosoma is based on their work. They found that at least two subspecies should be regarded as full species. This involves splitting Western Quail-thrush, Cinclosoma marginatum from Chestnut-breasted Quail-thrush, Cinclosoma castaneothorax (both now monotypic) and Nullarbor Quail-thrush, Cinclosoma alisteri, from Cinnamon Quail-thrush, Cinclosoma cinnamomeum (including tirariense).

Chestnut Quail-thrush / Chestnut-backed Quail-thrush, Cinclosoma castanotum, is split into Copperback Quail-thrush, Cinclosoma clarum, and Chestnut Quail-thrush, Cinclosoma castanotum, based on Dolman and Joseph (2015).

Pachycephalidae: Whistlers Swainson, 1831

5 genera, 60 species HBW-12

Click for Pachycephalidae species tree
Click for Pachycephalidae
species tree

Genetic studies have done a number on the family. Although the core of it, the whistlers and shrike-thrushes, has remained unscathed, other taxa associated with the family have moved in or out. The pitohuis have been split into 4 genera, with Pitohui itself moving to Oriolidae and Ornorectes in Oreoicidae. The other three pitohuis have been retained in Pachycephalidae in two genera.

The shrike-thrushes have been included with the whistlers (Pachycephalidae) due to the analysis in Jønsson et al. (2008b, 2010a). They also found that the former Olive-flanked Whistler (Hylocitrea bonensis, now called Hylocitrea) is not only not a whistler, but not even in Corvida. It belongs somewhere in Passerida.

Pitohuis: Although it turns out that they are not all that closely related, the pitohuis share an interesting characteristic. They're poisonous! (Dumbacher et al., 1992.) You can read more about these birds at Dumbacher's website and an article in American Birds. The exact relationships of these toxic species has not been exactly clear, so we shouldn't be entirely surprised that they have split apart. A paper by Jønsson et al. (2008a) found that the pitohuis are not that closely related to each other. Accordingly, they end up in four genera: Ornorectes (Oreoicidae), Pitohui (Oriolidae), Pseudorectes (Pachycephalidae), and Melanorectes (Pachycephalidae).

Shrike-thrushes: Based on Jønsson et al. (2008b, 2010a), The Sangihe Shrike-thrush has been transferred to Coracornis. Using different data sets, Dumbacher et al. (2008) and Jønsson et al. (2008b, 2010a) found that the Morningbird, which is sometimes placed in Colluricincla, sometimes in Pitohui, actually belongs in Pachycephala. The fact that the Morningbird is not in Colluricincla causes a change in the scientific name of the Sooty Shrike-thrush. With Colluricincla tenebrosa of Hartlaub and Finsch (1868) no longer using tenebrosa, the Sooty Shrike-thrush retakes the name tenebrosa (Rothschild 1911) which has priority over umbrina (Reichenow 1915).

Whistlers: The current arrangement of the whistlers is based on Jønsson et al. (2008c, 2009, 2010a, 2014) and Andersen et al. (2014b). I have not strictly followed the phylogeny in Anderseen et al., but have kept several lumped together several closely related taxa that may their phylogeny splits. Even so, I recognize 8 additional species:

  1. Bougainville Whistler, Pachycephala richardsi, split from Hooded Whistler, Pachycephala implicata.
  2. Louisiade Whistler, Pachycephala collaris, split from Bismarck Whistler, Pachycephala citreogaster.
  3. Rossell Whistler, Pachycephala rosseliana, split from Bismarck Whistler, Pachycephala citreogaster.
  4. Rennell Whistler, Pachycephala feminina, split from Oriole Whistler, Pachycephala orioloides.
  5. Temotu Whistler, Pachycephala vanikorensis, comprised of subspecies utupuae and ornata from the White-throated Whistler, Pachycephala vitiensis, and vanikorensis from the Melanesian Whistler, Pachycephala caledonica.
  6. Timor Whistler, Pachycephala calliope, split from Yellow-throated Whistler, Pachycephala macrorhyncha
  7. Wetar Whistler, Pachycephala arthuri, split from Yellow-throated Whistler, Pachycephala macrorhyncha. Note that arthuri is often synonymized with calliope.
  8. Babar Whistler, Pachycephala sharpei, split from Yellow-throated Whistler, Pachycephala macrorhyncha.

Further, the remainging (i.e. Fijian) races of the White-throated Whistler, Pachycephala vitiensis, are lumped into the Fiji Whistler, Pachycephala graeffii. The name vitiensis has priority, so the Fiji Whistler is now Pachycephala vitiensis.

Several whistler subspecies also move around. The Yellow-throated Whistler, Pachycephala macrorhyncha, loses dammeriana which joins the Mangrove Golden Whistler, Pachycephala melanura. On the other hand, the Yellow Throated Whistler gains balim from the Australian Golden Whistler, Pachycephala pectoralis. The Mangrove Golden Whistler, Pachycephala melanura loses dahli, which joins the Golden-backed Whistler, Pachycephala aurea, which becomes Pachycephala dahli due to priority.

Further, the Western Whistler, Pachycephala occidentalis, which consists of the Western Australian populations formerly known as fulignosa, has been split from the Australian Golden Whistler, Pachycephala pectoralis based on Joseph et al. (2014b). The eastern populations of fulignosa remain as a subspecies of pectoralis. See also Andersen et al. (2014b) and Jønsson et al. (2014).

Both the Melanesian Whistler, Pachycephala chlorura, and Oriole Whistler, Pachycephala orioloides may require further splitting in the future.

Eulacestomatidae: Ploughbill Schodde and Christidis, 2014

1 genus, 1 species Not HBW Family (HBW-12:409)

The Ploughbill is a New Guinea endemic. HBW treated them as a basal whistlers, along with 6 other taxa that have also been removed from the whistlers. The others are Pachycare (Pardalotidae), Falcunculus (Falcunculidae), Oreoica and Aleadryas (Oreoicidae), Rhagologus (Rhagologidae), and Hylocitrea (Hypocoliidae).

Its closest relatives remain obscure. Aggerbeck et al. (2014) placed it sister to the sittellas. Other studies have come to different conclusions. Both Aggerbeck et al. (2014) and Jønsson et al. (2016) place it near a clade containing the painted berrypeckers, shrike-babblers, and vireos, as is done here.

Oriolidae: Orioles, Figbirds Vigors, 1825

7 genera, 40 species HBW-13

Click for Oriolidae species tree
Click for Oriolidae
species tree

The affinities of the recently extinct Piopios of New Zealand have long been uncertain. They have been variously considered birds-of-paradise, bowerbirds, thrushes, whistlers, and others. Sometimes they have been placed in their own family. There had been weak genetic evidence that they were close to bowerbirds. Two recent papers have now resolved the puzzle. Johansson et al. (2011) and Zuccon and Ericson (2012) found they are orioles!

The Oriolus orioles are widespread in the Old World, including Australasia. The other Oriolidae are confined to Australo-Papua (Pitohui, Sphecotheres) or New Zealand (Turnagra).

The arrangement here is primarily based on the analysis of Jønsson et al. (2010d), with some input from Johansson et al. (2011, 2016) and Zuccon and Ericson (2012). The genera are arranged as in Zuccon and Ericson (2012), which uses more genes, while Jønsson et al. (2010d) is followed for Oriolus. Jønsson et al. found evidence that Oriolus chinensis involves at least 3 species (there are 20 subspecies). It also is likely that steerii contains two or more species. The placement of crassirostris is a bit uncertain as it was not sampled.

Based on Dumbacher and Fleischer (2001), the Variable Pitohui has been split into three species: Southern Variable Pitohui, Pitohui uropygialis, Raja Ampat Pitohui, Pitohui cerviniventris, and Northern Variable Pitohui, Pitohui kirhocephalus. There's more information on pitohuis in the next section.

Based on Jønsson et al. (2016) as well as appearance, Oriolus has been separated into 4 genera. Brown Oriole though Tanimbar Oriole, which also have distinct skull morphology have been separated in genus Mimeta (Vigors and Horsfield 1827, type sagittata). Further, Dark-throated Oriole through Isabela Oriole have been placed in genus Xanthonotus (Bonaparte 1854, type xanthonotus). Finally, Black-and-crimson Oriole through Silver Oriole go in the genus Analcipus (Swainson 1831, type cruentus). The rest of the orioles remain in Oriolus (Linnaeus 1766, type oriolus)

The genetic results in Jønsson et al. (2010d) also support splitting Sunda Golden-Oriole, Oriolus maculatus, and Asian Golden-Oriole, Oriolus diffusus, from Black-naped Oriole, Oriolus chinensis. Jønsson et al. only included four of the twenty subspecies (melanisticus grouped with chinensis). Presumably Asian Golden-Oriole is monotypic, and mostly migratory. Sunda Golden-Oriole probably includes andamanensis, macrosurus, maculatus, mundus, richmondi, sipora lamprochryseus, and insularis, while Black-naped Oriole includes the Philippine races (chinensis, yamamurae, sulensis, and melanisticus). I'm not sure which group the Wallacean races belong to (sangirensis, formosus, celebensis, stresemanni, frontalis, bonratensis, and broderipi), and they are left in the Black-naped group until further information becomes available.

Paramythiidae: Painted Berrypeckers P. L. Sclater, 1893

2 genera, 2 species HBW-13

This family of New Guinea endemics was previously removed from the Melanocharitidae (Passerida) and placed in their own family in Corvida. It has been unclear whether they should be treated as a separate family, and the TiF list has sometimes included them in Psophodidae. Aggerbeck et al. (2014) found them to be a separate branch sister to Psophodidae and Vireonidae (presumably including Pteruthiidae). Jønsson et al. (2016) put them sister to the the Vireonidade and Pteruthiidae, about 26 million years distant from their closest relatives. The former is followed here.

Sibley and Ahlquist (1987) removed the painted berrypeckers from Melanocharitidae (berrypeckers and longbills), but left them in place near the flowerpeckers and sunbirds (others had previously questioned the affinities of these species). See also Sibley and Ahlquist (1990) and Sibley and Monroe (1990). Nonetheless, H&M-3 (Dickinson, 2003) still had them united in a single family, but now inside what I call Corvida. They were separated again in Barker et al. (2004), this time with the Paramythiidae located near Oriolus (as they are) and with the Melanocharitidae as basal Corvida near Callaeatidae. As previously mentioned, Irestedt and Ohlson (2009) recognized that Melanocharitidae, Cnemophilidae, and Callaeidae, were really basal Passerida, and that the RAG-1 gene had given a misleading signal. Aggerbeck et al.'s 22-gene analysis (2014) supports this interpretion.

Psophodidae: Whipbirds and Wedgebills Bonaparte, 1854

3 genera, 6 species HBW-12 in Eupetidae (pp. 370-2)

This small group of Australo-Papuan birds has been substantially reduced in size. I have previously treated these taxa and other possibily related taxa such as Paramythiidae in various ways (e.g., based on Norman et al., 2009a). The current version is based on Aggerbeck et al. (2014) and Jønsson et al. (2016), leaving a very narrowly circumscribed Psophodidae.

Other birds that have previously been considered to belong in this family include Cinclosoma and Ptilorrhoa (currently in Cinclosomatidae) and Eulacestoma, which is now in its own family. There is also some support for including Falcunculus (Falcunculidae), in Psophodidae (e.g, Barker et al., 2004; Dumbacher, 2008), but the multigene analyses of Jønsnon et al. (2016), Aggerbeck et al. (2014), Norman et al. (2009a) and Jønsson et al. (2011b) all separate them. Jønsnon et al. (2016) date each of these families as 23-25 million years old.

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. Barker et. al (2004) suggested that Melampitta belonged in the monarchs (Monarchidae), but with weak support. They and the mudnesters (Corcoracidae) were thought to form a clade. Reddy and Cracraft (2007), using the same genes, found Melampitta either with the monarchs or mudnesters. Dumbacher et al. (2008) found it related to Ifrita, but did not include the necessary taxa to say where they goes. Irestedt et al. (2008) considered Melampitta basal in the narrowly construed Corvoidea, while Norman et al. (2009a) include Ifrita with the monarchs, as do Jønsson et al. (2016). Jønsson et al. (2011b) put Ifrita with the monarchs and Melampitta in a clade containing the mudnesters and birds-of-paradise. Aggerbeck et al. (2014) have the mudnesters, Ifrita and Melampitta in a clade with the birds-of-paradise. In any event, they do not belong here.

Psophodidae species tree
Psophodidae species tree

Jønsson et al. (2007) showed that the rail-babbler Eupetes was really related to Chaetops and Picathartes. It is now in its own family Eupetidae within Passerida.

The Psophodidae have been rearranged and divided into three genera based on Toon et al. (2013) and Jønsson et al. (2016). The three genera are used because the divisions within the family are deeper than usually supposed. The genus Androphobus has been merged into Psophodes because Jønsson et al. (2016) found it is sister to the Eastern Whipbird. The Wedgebills take the genus name Sphenostoma (Gould 1838, type cristatum) and the Western and Mallee Whipbirds become genus Phodopses (Schodde and Mason 1999, type nigrogularis).

Pteruthiidae: Shrike-babblers Informal?

1 genus, 9 species Not HBW Family (HBW-12:284-6)

Pteruthiidae species tree
Pteruthiidae species tree

I had previously treated this Indo-Malayan group as a subfamily of the vireos. They are fairly distantly related to the vireos, with a common ancestor about 23 million years ago according to Jønsson et al. (2016), so I have given them their own family. Nonetheless, there doesn't seem to be any question that they are sister to the vireos.

Reddy (2008), using the phylogenetic species concept, advocated splitting Pteruthius into 19 species. While this seems extreme, Reddy's evidence suggests that 5 species were too few. Rheindt and Eaton (2009) reexamined the issue taking into consideration plumage, morphology, and vocalizations. Combining this information with Reddy's genetic analysis, they suggest that Pteruthius contains 9 biological species. Their treatment is followed here.

Vireonidae: Vireos Swainson, 1837

7 genera, 57 species HBW-15

Next come the vireos. They were once thought to be closely related to the wood-warblers (Parulidae). When Sibley and Ahlquist discovered the corvid group, they found that the vireos (and shrikes) were members of it. Some thought it odd that the vireos, with an old world origin, had no remaining old world members. It is true that it seemed odd. But it is false that there are no old world members.

The old world vireos and relatives have been hiding out among the babblers (Timaliidae), living in southeast Asia and the Himalayas. The first to be noticed was Erpornis zantholeuca (nee Yuhina zantholeuca). Cibois et al. (2002) discovered it was not a babbler, but belonged somewhere in the Corvida. Rather than being a babbler like the other Yuhinas, it is actually a vireo relative (Barker et al., 2004).

Reddy and Cracraft (2007) found that the shrike-babblers (Pteruthius) are not babblers at all, but are vireo relatives. I currently list them in their own family, sister to the vireos, but it would also be reasonable to treat them as a subfamily of the vireos.

The current arrangment of the Vireoninae (what was traditionally considered the vireo family) is based on Slager et al. (2014) (see also the preliminary results posted by Battey, 2014). They sampled most of the taxa. The conventional Hylophilus turned out to be paraphyletic. To solve this, one species moves to Vireo (Tepui Greenlet, now Tepui Vireo, Vireo sclateri) and the remaining Hylophilus are split into three genera: Hylophilus (scrub greenlets), Tunchiornis (tawny-crowned greenlets, Slager and Klicka, 2014b), and Pachysylvia (canopy greenlets, Bonaparte 1850, type decurtata). Vireo remains unchanged except for the addition of the Tepui Vireo (nee Greenlet). The concatenated analysis placed the scrub greenlets (Hylophilus) sister to the peppershrikes (Cyclarhis), branching before the Shrike-Vireos (Vireolanius) which are basal to the remaining taxa.

It's unclear whether the two peppershrikes are reciprocally monophyletic. They are not in ND2, but are in the Z-linked genes studied by Slager et al. (2014). There is also a substantial amount of genetic distance within the Rufous-browed Peppershrike, Cyclarhis gujanensis, and more than one species might be involved. Further study is needed to clarify matters, especially as there is little vocal variation among the subspecies (Tubaro and Segura, 1994), with the main difference depending on climate and habitat (more high frequencies in closed habitats, and more bandwidth in the tropics).

Another potential split involves the Slaty-capped Shrike-Vireo, Vireolanius leucotis. The one sample from western Ecuador (subspecies mikettae, sampled from Lita, in Esmeraldas province) did not group with the birds east of the Andes in ND2.

The Golden Vireo (Golden Greenlet?) moves to Pachysylvia. The Red-fronted Greenlet, Tunchiornis rubrifrons, has been split from Tawny-crowned Greenlet, Tunchiornis ochraceiceps. Further research may support additional splits in the ochraceiceps complex, particularly between the Red-fronted Greenlets north and south of the Amazon.

When possible, the species tree includes available subgeneric names in italics for the various clades within Vireo. The four subgenera are spectacled vireos, Lanivireo (Baird 1858, type flavifrons); the eye-ringed vireos, Vireo (Vieillot 1808, type griseus); the eye-lined gilvus group, Melodivireo (Oberholser 1974, type gilvus); and the eye-lined olivaceus group, Vireosylva (Bonaparte, 1838, type olivaceus). And yes, that's the way Bonaparte spelled Vireosylva, so we're stuck with it.

Slager et al. (2014) found that the Central American Vireo, Vireo notius (inc. montanus), is basal in the Solitary Vireo group. It has accordingly been split from Plumbeous Vireo, Vireo plumbeus. Although genetic data is not available, the subspecies notius and montanus differ in appearance and are candidates for a further split.

Slager et al. (2014) found that Brown-capped Vireos of Mexico and northern Central America are genetically distinct from the remaining Brown-capped Vireos, Vireo leucophrys. Further research may lead to a split.

Warbling Vireo, Vireo gilvus, has been split into the monotypic Eastern Warbling-Vireo, Vireo gilvus, and Western Warbling-Vireo, Vireo swainsoni. They differ vocally, in morphometrics, molt and migration timing (Voelker and Rohwer, 1998) and the genetic distance supports their treatment as distinct species (Murray et al., 1994; Slager et al., 2014).

I have also split the South American Chivi Vireo, Vireo chivi, from Red-eyed Vireo, Vireo olivaceus. Slager et al. (2014) sampled Red-eyed Vireos from 6 locations and 18 Chivi Vireos and found that they are not sister taxa. Interestingly, the Black-whiskered Vireo, the local breeding member of the Red-eyed complex (flavoviridis through chivi) here in Miami is better thought of a a northern form of Chivi Vireo, rather than a southern form of Red-eyed. Both the Yellow-green and Yucatan Vireo developed from the Red-eyed complex prior to the Red-eyed/Chivi split.
