n Utah and s Wyoming s to e Calif., c Arizona, s New Mexico and w Texas.

This species formerly was divided into Slate-colored, Oregon (including Pink-sided), White-winged and Gray-headed juncos, but these forms intergrade freely, sometimes forming wide areas where intergrades occur, except where suitable nesting habitat is restricted.  Rarely hybridizes with Zonotrichia albicollis -- see above under that species.

Passerculus sandwichensis  SAVANNAH SPARROW.  Grasslands, tundra, meadows, bogs, farmlands, marshes; salt marshes.

Several subspecies groups are morphologically, genetically and perhaps vocally distinct and could be treated as species, although all but sanctorum either hybridize to varying degrees or are connected by intermediate populations.  Following from Rising (1993. Birds of N. Amer. 45:2-3).

 Pipilo:  This genus is based on Pipilo erythrophthalmus (Linnaeus 1758).  The interspecific hybrids described below show that erythrophthalmus, ocai and chlorurus are closely related.  However, the Brown Towhee group (aberti, crissalis, fuscus, albicollis) may not be congeneric with Pipilo, but may be closer to Melozone (Sibley, pers. opinion based on field observations of behavior).
-

-
 Hybridization:  The extensive and complex pattern of hybridization between the morphologically distinct species, P. ocai and P. erythrophthalmus, was studied by Sibley (1950. Univ. Calif. Publ. Zool. 50:109-194) and (1954. Evolution 8:252-290); Sibley and West (1958. Auk 76:326-338) and Sibley and Sibley (Auk 81:479-504).  Pure ocai is found alone in Guerrero.  In Oaxaca, where elevational overlap occurs between the two species, there is no hybridization.  In eastern Puebla occasional hybridization occurs on Mt. Orizaba and the incidence of hybridization increases n to w Veracruz.  From Hidalgo s to México and w to Michoacán, there is a hybrid cline from erythrophthalmus-like birds in the east to ocai-like birds in the west.  The approximate midpoint is near Morelia.  Isolated mountain-top hybrid populations range from nearly pure ocai in Colima to nearly pure erythrophthalmus in n Jalisco.  On Cerro Viejo, a mountain on the n shore of Lake Chapala, only hybrids occur and similar populations are present on other isolated mountains in this region.  Pure erythrophthalmus populations are found n of the s Sierra Madre Occidental and in Chiapas and Guatemala where ocai does not occur.

The Green-tailed Towhee (P. chlorurus) has hybridized with the Rufous-sided Towhee as indicated by a photograph in Birding, vol. 26:174, 1994.  The Green-tailed is the northern representative of the Collared Towhee and it is not surprising that hybrids between Rufous-sided and Green-tailed should occur.  The photograph of the hybrid shows the white throat and rufous cap of the Green-tailed, characters shared with the Collared Towhee (P. ocai), with other plumage areas like the Rufous-sided.

Pipilo erythrophthalmus  RUFOUS-SIDED TOWHEE.  Undergrowth of open woodland, forest edge, second growth, brushy areas, chaparral, riparian thickets.  From s British Columbia e across sw Canada to s Saskatchewan and s to s Calif., incl. Channel Is., nw,s Baja Calif, s Nevada, wc,s Arizona through Mexican highlands to Chiapas and c Guatemala and e to c Dakotas, nc,w Nebraska, ne,c Colorado, e New Mexico and extreme w Texas; from s Manitoba e across s Canada to sw Quebec, n New York and c New England and s to ne Texas, ne,sc Louisiana, Gulf coast, w to Mississippi and s Florida; Revillagigedo Is. on Socorro I.; highlands of c Mexico in e Michoacán, México, Distrito Federal, Morelos, s Tlaxcala, w Puebla and n,c Oaxaca.  See Hybridization under P. ocai, above.

Eastern plain-winged (erythrophthalmus) and western spotted-winged (maculatus) races formerly were treated as species.  They differ vocally and a preliminary report suggests that they have distinct mtDNA profiles, but they hybridize in suitable habitat across the Great Plains producing a wide variety of plumage patterns.  Eastern populations often have small white spots on the scapulars, even on Long Island, New York.

Pipilo aberti  ABERT'S TOWHEE.  Desert scrub, esp. near water, riparian thickets.  From se Calif., se Nevada, sw Utah, c,se Arizona and sw Mexico se to ne Baja Calif. and nw Sonora.
Pipilo crissalis  CALIFORNIA TOWHEE.  Brushlands, arid scrub, chaparral, mesquite, riparian thickets, around human habitation.  Pacific lowlands from sw Oregon s through Calif, w of Sierra Nevada and sw desert region to s Baja Calif.

Allozymes, mtDNA profiles and morphometric studies indicate that P. fuscus is closer to P. albicollis than to P. crissalis, thus recognition of fuscus and crissalis as species is warranted.  Furthermore, mtDNA studies demonstrated that P. aberti and P. crissalis are sister taxa, with the relationship of P. fuscus and P. albicollis less strongly supported.

Pipilo albicollis  WHITE-THROATED TOWHEE.  Arid scrub, undergrowth of pine-oak.  Mts. of c Mexico in e Guerrero, s Puebla and Oaxaca, w of Isthmus of Tehuantepec.

Gill (1994. J. für Orn. 135:359) summarized the well-known hybridization between V. pinus and V. chrysoptera in eastern North America. 
The situation is relatively recent and involves range expansion, hybridization and replacement of one species by a close relative.  Southern V. pinus has been expanding northward and hybridizing with northern chrysoptera where they come into contact.  Local populations include phenotypically "pure" individuals of both species and birds that are mixtures of the characters of both parental types.  The composition of populations changes as the hybrid zone moves northward.  Comparisons of mtDNA's suggest that pinus mtDNA introgresses rapidly into chrysoptera phenotypes without comparable reverse introgression of chrysoptera mtDNA into pinus.  Field identifications at the species level in or near the hybrid zone should be considered uncertain.

Tribe THRAUPINI:  
Tanagers.  Bananaquit, Conebills, Bush-Tanagers, Hemispingus, Palm-Tanagers, Shrike-Tanagers, Ant-Tanagers, Mountain-Tanagers, Euphonias, Chlorophonias, Honeycreepers, Dacnis, Swallow-Tanager, Plushcap, Finch-Tanagers, Sierra-Finches, Diuca-Finches, Warbling-Finches, Yellow-Finches, Grass-Finches, Grassquits, Seedeaters, Seed-Finches, Flower-piercers, Orangequit, Ground-Finches, etc.
 Like the New World suboscines (Tyranni), the tanagers apparently evolved in South America during its long isolation from other continents.  The finch-billed tanagers were placed in the Emberizidae or Fringillidae in the past, but DNA hybridization comparisons showed that they are thraupines that adapted to the ecological niches in the Neotropics that are occupied by emberizine and fringilline finches elsewhere.  The nectar-feeding tanagers, including Coereba, Conirostrum, Diglossa, Cyanerpes, Chlorophanes, Iridophanes, Dacnis, Hemidacnis, Xenodacnis, Ateleodacnis, Oreomanes and Euneornis were often placed in the family Coerebidae.  In other treatments some of these genera were placed with the Wood Warblers (Parulini) and other arrangements have been used.  The Swallow-Tanager was usually placed in the monotypic Tersinidae or Tersininae and the Plushcap in the monotypic Catamblyrhynchidae.  The Thraupini herein defined includes what seem to be the results of an extensive adaptive radiation in South America that produced ecotypes that resemble the true finches and other groups.  The problem is complicated by the fact that the tanagers are closely related to the emberizines, parulines, cardinalines and icterines -- in this classification all are placed in the Emberizinae, but additional molecular data may modify this classification.  Morphological differences are mainly those associated with feeding, such as bills and tongues, which are especially subject to convergent evolution.  Details of thraupine phylogeny remain to be clarified.  See Bledsoe (1988.  Auk 105:504-515) and Sibley and Ahlquist (1990) for the molecular evidence.

Coereba flaveola  BANANAQUIT.  Scrub, woodland, second growth, towns, mangroves, forest, from humid to xeric habitats.  Lowlands in Bahama Is., from Grand Bahama and Little Abaco s to Great Inagua and Turk Is.; lowlands to 2000 m of W. Indies (but not Cuba and Swan Is.) and Mexico from c Veracruz, n Oaxaca, Chiapas and is. off Yucatán Pen., incl. Holbox, Cancun, Cozumel is. and Cayo Culebra, s in Caribbean lowlands to Nicaragua, both slopes of Costa Rica and Panama, incl. Coiba and Pearl is., Venezuela, Trinidad, Tobago and Guianas s, w of Andes, to nw Peru and, e of Andes, to e Peru, n,e Bolivia, Paraguay, ne Argentina and Brazil.

Seutin, et al. (1994. Evolution 48:1041-1061) analyzed mtDNA restriction-site variation in Bananaquit population samples from 12 Caribbean islands and 5 localities in Central and n South America.  The Jamaican birds are the most divergent; C. American, n S. American and e Antillean (Puerto Rico to Grenada) are nearly equally divergent among themselves and may represent a single, recent range expansion.  In the e Antilles three groups were identified: Puerto Rico, n-c Lesser Antilles (U.S. Virgin Is. to St. Lucia), and Grenada-St. Vincent.  The results suggest a series of range changes with strong geographic variation over small distances.  
The mtDNA data were consistent with several subspecific units, but named subspecies do not define equally differentiated populations.
