Which family formally classifies the New World warblers?
Answer
Parulidae
The New World warblers, which are highly diverse and successful across the Americas, are formally placed within the family Parulidae. This grouping represents a distinct evolutionary lineage separated from the Old World warblers. Molecular studies were instrumental in confirming this distinction, showing that Parulidae species do not share a recent common ancestor with the Sylviidae lineage. This family is recognized for its approximately 100 species, often characterized by active foraging habits and sometimes bright plumage patterns, and they are scientifically positioned within the superfamily Passeroidea.
