Field notes

  • It was named by Robert Ridgway in 1870 to honor Adelaide Swift, the daughter of the man who collected the first specimen.
  • The species was formerly considered conspecific with the Barbuda Warbler and the St. Lucia Warbler until they were split based on vocal and morphological differences.
  • Pairs are known to be monogamous and maintain their territories year-round rather than migrating.
  • It is a versatile forager that often gleans insects from the undersides of leaves and occasionally performs 'hover-gleaning' to catch prey.
  • The nest is a compact cup constructed of grass, fine roots, and spider webs, usually hidden in dense mid-story vegetation.
Habitat
Subtropical dry forests, moist limestone forests, and shade coffee plantations.
Range
Endemic to the main island of Puerto Rico and Vieques.
