If you're paying attention to the names of the higher-level groups, this one may leave you scratching your head. What's Emberizoidae? Is it a typo for Emberizoidea?
It is not a typo, but is the ending for an epifamily, a rarely used group between family and superfamily. I've resorted to it here to emphasize that the following families are more closely related to each other than to anything else.
Sibley and Monroe (1990) used the name “Emberizinae” for the remaining species. They were using an absolute measure of genetic distance to separate families and other groups. By the time you get here, everything is closely enough related to fit in a single Sibley-Monroe subfamily. In fact, even all of the nine-primaried oscines end up in the same family!
I use terms such as order and family in an ordinal, not cardinal, fashion. This lets me refer to the Sibley-Monroe “Emberizinae” as the epifamily Emberizoidae. This gives me a little more headroom, but as you will see below, I'm still running out of levels.
All but two of the families in Emberizoidae are restricted to New World. The exceptions are Calcariidae and Emberizidae itself. The latter seems to have its origin in the New World.
The topology of the remaining Emberizoidae families is still unclear. Klicka et al. (2003) had Parulidae sister to Passerellidae, while Barker et al. (2013) give a species tree showing Emberizidae and Passerellidae as sisters, but their concatenated tree shows Emberizidae basal and Passerellidae sister to the blackbird/warbler clade. Klicka et al. (2007) has Emberizidae and Passerellidae sister, with Icteridae sister to that, and Parulidae sister to the rest.
The fact that Barker et al.'s (2013) study was unable to find definitive answers as to how these families are related was not due to lack of trying. They analyzed DNA from 6 genes and every genus in Emberizoidae (genera as given by the Howard-Moore checklist (Dickinson, 2003)). Although the standard families were well-supported, this cannot be said about their relationships or inner structure. Moreover, a number of taxa did not consistently fall into any of the standard Emberizoidae families: Rhodinocichla, Icteria, Teretistris, Zeledonia, Phaenicophilidae, and Mitrospingidae.
The basic problem seems to be very rapid diversification. All of Emberizoidae, about 8% of all bird species, share a recent common ancestor. Barker et al. estimate this ancestor lived roughly 15 million years ago and some of the families date from a mere 10 million years ago. With such recent diversification, issues such as speciation before lineages can sort out make it particularly difficult to reconstruct the actual species tree from inconsistent gene trees. More data will be needed to completely sort this out, and it will probably not happen quickly.
|TiF Emberizoidae Phylogeny|
The TiF list now uses a compromise phylogeny based on the two Barker et al. (2013) estimates using all data. The Calcariidae are basal. The relationship between the Emberizidae and Passerellidae is left unresolved. The remaining Emberizoidae are arranged in two groups, a clade containing the blackbirds and warblers and some Antillean Tanagers, and a thraupid clade consisting of the cardinals, tanagers, and Mitrospingidae. The exact limits of most of these families have been the subject of a lot of research. Although we mostly know the boundaries of these families, we are still uncertain about where a few genera go. Besides the aforementioned Rhodinocichla, the genera Teretistris and Zeledonia are not currently assigned to families, although Teretistris and Zeledonia belong to the blackbird/warbler clade.
Calcariidae: Longspurs, Snow Buntings Ridgway, 1901
2 genera, 6 species Not HBW Family
Genetic evidence shows the longspurs and snow buntings are not part of Emberizidae (buntings) or Passerellidae (American sparrows). Rather, they should be placed in their own family, Calcariidae, which is a basal branch in the Emberizoidae (Klicka et al., 2003). It was also necessary to revive Rhynchophanes for McCown's Longspur in order to avoid lumping the whole family in one genus. Putting snow buntings and longspurs in one genus just didn't seem right.
The structure as found by Klicka et al. (2003) is that Rhynchophanes and Plectrophenax are sister genera, and the two together are sister to Calcarius. Maley and Wink (2010) found that McKay's Bunting, Plectrophenax hyperboreus, has only recently separated from Snow Bunting, Plectrophenax nivalis, apparently during the last glaciation. There's evidence that its population was once much larger, possibly being widespread in Beringia.

1 genus, 1 species
The classification of the Thrush-Tanager has long been an issue. Originally considered an ovenbird by Lesson (Furnarius roseus), Hartlaub placed it in its own genus, Rhodinicichla in 1853. Since then, its classification has varied. It has been considered a type of warbler, wren, or thrasher, with names such as thrush-warbler or wren-warbler. It was eventually recognized as a nine-primaried oscine of some sort. Clark (1913) argued that it was a tanager due to similiarities with Mitrospingus, but we don't consider Mitrospingus to be a tanager. Skutch (1962) suggested it might need its own family. Eisenmann (1962) replied with an analysis meant to convince us that Rhodinocichla is a tanager. In retrospect, Eisenmann's reply is unconvincing due to the fact that many of possibly related birds he mentions are no longer part of Tharupidae.
Barker et al. (2013) is the only paper that analyzes DNA from the Rosy Thrush-Tanager. Their results are rather inconclusive. The species tree places it sister to Calcariidae, although this is rather hard to swallow. The concantenated gene tree puts it sister to the remaining Emberizoidae. The mitochondrial tree puts it sister to Thraupidae. Support for any of these options is weak and I was intending to leave it unclassified even though Barker et al. suggest treating it as a separate family, Rhodinocichlidae. The discussions in Clark (1913), Eisenmann (1962), and Skutch (1962) convinced me this really is a unique taxon, and that it deserves family status.
The thrush-tanager's range is somewhat disjoint. Ridgway (1902) considered the Mexican race a distinct species. The Central and South American forms are distinct, and may also be separate species.

There is some uncertainty concerning whether the Emberiza buntings and American sparrows are sister clades, and that is why I have them in separate families. For example, Klicka et al. (2003) has Emberizidae embedded in the Icteridae while Passerellidae is sister to Parulidae. Taxonomy within Emberizidae follows Alström et al. (2008a), with Melophus and Latoucheornis included in Emberiza. They identify four major clades, which could be regarded as subgenera: Fringillaria, Melophus, Emberiza, and Schoeniclus (the last has priority over Cynchramus). There has been some adjustment of the phylogeny based on Ren et al. (2014).
Should anyone feel inclined to further divide this genus, there are available names for the main subclades of these clades. For one such possibility, see the species-level tree for Emberiza. The groupings are in general agreement with the morphological groups of Byers et al. (1995). Their Yellowhammer group is subgenus Emberiza; the Rock Bunting group is Cia; the Ortolan Bunting group is Glycyspina; the House Bunting group and Golden-breasted bunting group are both clades within Fringillaria. Not all of Byers et al.'s species pairs are supported. The question marks on the tree indicate species not analyzed by Alström et al. (2008). The Socotra Bunting, Emberiza socotrana, was not included in Alström et al.'s analysis, but was analyzed by Schweizer and Kirwan (2014).

Passerellidae: American Sparrows Cabanis & Heine, 1850-51
28 genera, 136 species HBW-16 (split)
|Click for genus-level tree|
The sparrow family has been carved up in the ongoing reorganization of the nine-primaried oscines. Most of the Neotropical finches have joined the tanagers. The Gubernatrix and Paroaria cardinals have been moved to the tanagers. The Neotropical finches that remain are the Atlapetes brush-finches, as well as the Large-footed, Yellow-thighed, and Yellow-green Finches (Pezopetes and Pselliophorus. In return, the sparrows gain the genus Chlorospingus (excepting flavovirens) and the Tanager Finch, Oreothraupis arremonops. These changes alone would reduce the family to about half its former size, but there is more. They also lose the Emberiza.
What remains is a somewhat more homogeneous family and it is possible to give it a coherent organization. Everything seems to fall into 8 clades, most of which I've treated at the tribe level (I have united two of them). I haven't used subfamilies partly because I don't think it's clear yet how the tribes fit together, and partly because I don't think the divisions are particularly deep.
The correct arrangement of the Passerellidae tribes remains unclear. The version presented here is based on Klicka et al. (2014) and is similar to previous arrangements based on Barker et al. (2013), which has Spizellini as the basal group. There is enough uncertainty (Carson and Spicer, 2003, DaCosta et al., 2009, and Klicka et al., 2007 all have slightly different arrangements) that I leave it as part of a basal trichotomy. All put the remaining tribes in the third branch of the trichotomy.
We consider the Spizellini first. As shown by Carson and Spicer (2003), this clade includes most of the Spizella sparrows. The genus Amphispiza is restricted to the Five-striped Sparrow and the Black-throated Sparrow, but does not include the sage sparrows. The arrangement within Spizella follows Canales-Del Castillo et al. (2010), with Brewer's Sparrow somewhat surprisingly sister to Worthen's Sparrow. The Timberline Sparrow, Spizella breweri taverneri, is sometimes thought to be a separate species. Although there is some differentiation between it and Brewer's Sparrow, it may be best thought of as an incipient species within Brewer's Sparrow. See Klicka et al. (1999).
This brings us to Ammodramini, where some genera have required reorganization. Ammodramus and Aimophila have been affected the most. The papers by Klicka and Spellman (2007) and DaCosta et al. (2009) show what to do. Ammodramus itself is reduced to the Grasshopper Sparrow together with a couple of Neotropical relatives. These are sister to Arremonops. Together, they are sister to a big chunk of what was Aimophila. As the Aimophila type species is not included, I have revived Audubon's 1839 name for them, Peucaea (type aestivalis). Two more of the former Aimophila are sister to the rest of Ammodramini. Following DaCosta et al.'s suggestion, they take the genus name Rhyncospiza (Ridgway 1898, type stolzmanni).
The other big group in Ammodramini consists of a some Neotropical sparrows. These have been all merged into the genus Arremon. Although there are 4 distinct groups, the actual branching order remains a bit unclear (see Cadena et al., 2007 and Flórez-Rodríguez et al., 2011). One of the leading candidates is illustrated on the tree.
The groups are the two former Lysurus finches, the brunneinucha/virenticeps complex, which may actually hide a half-dozen species (Navarro-Sigüenza et al., 2007), the torquatus group, which has been split into 8 species (Cadena et al., 2007, 2010, 2011; also see SACC proposal #468), and the Arremon sparrows. The split of the Stripe-headed Brush-Finch (torquatus group) is detailed below. The English names follows AOU's NACC and SACC

Chlorospingini consists of Chlorospinus and the Tanager Finch (Oreothraupis) Although it had been suggested that the Tanager Finch belongs with the Atlapetes Brush-Finces, Barker et al. (2013) found it sister to Chlorospingus. The treatment of the Common Chlorospingus complex is based on García-Moreno et al. (2004), Sánchez-González et al. (2007), Bonaccorso et al. (2008), and Weir et al. (2008). This involves breaking up the Common Chlorospingus into 9 species. Four of these are primarily Mexican: White-fronted Chlorospingus, C. albifrons; Wetmore's Chlorospingus, C. wetmorei; Brown-headed Chlorospingus, C. ophthalmicus; and Dwight's Chlorospingus, C. dwighti. The color plate in Sánchez-González et al. (2007) illustrates these forms as well as Dusky-headed Chlorospingus, C. postocularis. Other taxa that appear to deserve species status are the Central American Dotted Chlorospingus, C. punctulatus; the Buff-breasted Chlorospingus, C. cinereocephalus, of Peru; and the Yellow-breasted Chlorospingus, C. flavopectus. The list of subspecies below presumes that Isler and Isler's (1987) flavopectus group stays together, although only two of its subspecies were analyzed by Weir et al. (2008). I've also presumed that Isler and Isler's venezuelanus group stays together. Weir found that some of them group with several more southern races. For the present, it seems reasonable to put the whole lot of them in a single species and call it Common Chlorospingus, C. venezuelanus. There may still be additional species hiding within the Common Chlorospingus complex.
|The Common Chlorospingus Complex|
|Wetmore's Chlorospingus||wetmorei||Mexico: Sierra de Tuxtla|
|White-fronted Chlorospingus||albifrons, persimilis||Mexico: Sierra Madre del Sur|

*An asterisk indicates taxa not sampled by Weir et al. (2008). The subspecies ‘novicius’ may be a hybrid form.
The third group of sparrows includes three tribes: Passerellini, Passerculini, and Pipilonini. Although there is consensus that they are each other's closest relatives, it remains unclear exactly how they relate. Barker et al. (2013) supports treating Passerellini and Passerculini as sisters, as is done here.
The Junco/Zonotrichia clade Passerellini is first. It is now clear that the American Tree Sparrow is not part of Spizella. Rather, it is most closely related to the Fox Sparrow, Passerella iliaca (Carson and Spicer, 2003). Slager and Klicka (2014) established the new genus Spizelloides for it. The Passerella/Spizelloides group forms a clade with the juncos and Zonotrichia. Passerella iliaca itself remains controversial, and may end up being split into four species. The Guadalupe Junco, Junco insularis, has been split from J. hyemalis (it is actually sister to hyemalis + phaeonotus, see Klicka et al., 2014).
The rest of Ammodramus ends up in the Passerculini. The “marshland” Ammodramus form a clade. As Klicka and Spellman (2007) recommend, they get the name Ammospiza. Although Henslow's and Baird's Sparrows may be each other's closest relatives, it is also possible they are not. Since there is only one available genus name between them, I've put them both in Centronyx (Baird 1858, type bairdii). Note that Nemospiza is preoccupied by an arachnid, and is not available. The sage sparrows get a brand new genus name. Klicka and Spellman (2007) discovered that it is not related to the other Amphispiza. The name they proposed, Artemisospiza, did not strictly follow ICZN rules. In view of this, Klicka and Banks (2011) proposed the name Artemisiospiza (think sagebrush, Artemesia). Moreover, the AOU, after considering Cicero and Koo (2012), now treats the Sage Sparrow as two species: Bell's Sparrow, Artemisiospiza belli, and Sagebrush Sparrow, Artemisiospiza nevadensis. The situation is rather confusing and a third species may be involved.
DaCosta et al. (2009) resolved a big chunk of the uncertainty concerning the Pipilonini. The Melozone Ground-Sparrows end up in two (or three?) separate groups. One part is sister to the brown towhees. DaCosta et al. suggest the genus name Pyrgisoma for it. The AOU proposal suggested the type is kieneri, although Ridgway gives the type as biarcuata. Apparently, treating kieneri as type dates from a time when biarcuata was considered a subspecies of kieneri. However, when separate, kieneri becomes the type species of Kieneria (Bonaparte 1855) and biarcuata is the type of Pyrgisoma. Since biarcuata ends up in the genus Melozone, Kieneria is the name used here. The brown towhees have always been considered different, and there have been suggestions they should get their own genus. That has never happened, so my best option seems to be to put them into Kieneria too. Surprisingly, the Zapata Sparrow, Torreornis inexpectata, thought to be sister to Amphispiza, turns out to be sister to Kieneria (Barker et al., 2013).
The other part of Melozone is merged into Aimophila because they are apparently successive sisters to the core Aimophila. This is surprising as a look at them makes it seem they must be sisters. Barker et al. (2013) found the Large-footed Finch, Pezopetes capitalis, to be basal to both, although support for this was not great.
The rest of the Pipilonini consists of the Pipilo towhees together with the Atalapetes brush-finches and allies. The extinct Bermuda Towhee, Pipilo naufragus, has been included as it seems to have survived into historical times. See Olson and Wingate (2012).
The Pselliophorus are embedded in Atlapetes, so I have changed their scientific names according. Klicka et al. (2014) present a comprehensive molecular phylogeny of Atlapetes which includes almost all of the Atlapetes species. The linear order is based on their phylogeny.
