Taxonomic Comments
Phylogenetic analyses of sequences of mitochondrial and nuclear DNA (Lovette et al. 2010) indicate that all species formerly placed in Dendroica, one species formerly placed in Wilsonia (citrina), and two species formerly placed in Parula (americana and pitiayumi) form a clade with the single species traditionally placed in Setophaga (ruticilla). The generic name Setophaga has priority for this clade (AOU 2011).
Paynter (1968) no longer recognizes subspecies of Dendroica virens.

Threat ImpactVery high - medium
Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Rank Reasons
Restricted range, widespread habitat loss, and dramatic, continuing population declines.
Range Extent Comments
Breeding range restricted to a narrow band of outer coastal plain habitat along the South Atlantic Coastal Plain from Virginia to South Carolina (Watts et al. 2011). Winters in Caribbean Basin.
Threat Impact Comments
Removal of Atlantic white cedar (Chamaecyparis thyoides) a century ago is presumably the cause of long-term population (90%) decline (Watts et al. 2011, Bryan Watts, pers. comm. 2017). In recent decades, much of their remaining habitat has been converted to pine plantations or for agricultural production (Bryan Watts, pers. comm. 2017. Birds wintering range is in Caribbean Basin, where there may be additional threats.
