Prairie Warbler (Setophaga discolor)

Taxonomy

Taxonomy:

Sylvia discolor

Vieillot

, 1809,

“the Antilles”, in Caribbean

Species is sister to S. vitellina, but suggestion that the two are conspecifics rejected by recent molecular study#R. Two subspecies recognized.

Subspecies and Distribution

S. d. discolor (Vieillot, 1809) – SE Canada (SE Ontario) and E USA E from NW Michigan, SE Iowa, E Kansas and E Texas and S from extreme S Maine (but excluding S coastal areas and most of Florida and Mississippi Valley); migrates to peninsular Florida, Caribbean and islands off coast (also small numbers on adjacent mainland) of C Central America.

S. d. paludicola (A. H. Howell, 1930) – coastal S Florida.

— Show family text —

Previously considered to include species now separated in Peucedramidae, Zeledoniidae and Teretistridae, as well as two genera now in Phaenicophilidae. The most comprehensive molecular phylogeny of present family to date#R recovered nine principal clades; almost all genera correspond to well-supported units, while two confined to West Indies are maintained based on other characters. Several traditionally recognized genera prove to be paraphyletic or otherwise unsustainable: Dendroica is abandoned because Setophaga is nested within it and has priority; Ergaticus is embedded within the clade occupied by Cardellina; Euthlypis is subsumed within Basileuterus; Oporornis is restricted to one species while its former congeners are removed to Geothlypis; Parula proves to be widely paraphyletic (two species move to Setophaga, the rest to a resurrected Oreothlypis); Phaeothlypis is indistinguishable from Myiothlypis; and the three Wilsonia are more correctly placed in Cardellina (two species) and Setophaga (one).

Genus: Setophaga Swainson, 1827

Previously restricted to a single species (S. ruticilla); but comprehensive molecular phylogeny reveals that this species is deeply embedded within large clade that includes two species formerly in Parula (S. americana and S. pitiayumi) and another (S. citrina) traditionally in Wilsonia, as well as all species previously treated in Dendroica#R; Catharopeza might also be subsumed into this genus#R, but better maintained as a separate monospecific genus, in view of unusual morphology and behaviour, as well as its basal position in the clade. As type species of Parula, Wilsonia and Dendroica are all included in present grouping, these names become synonyms of oldest available name for this clade, Setophaga.
