Family Sylviide
OLD-WORLD WARBLERS, KINGLETS, AND GNATCATCHERS.
This family is divided into three subfamilies: (1) The Sylviinæ, or Old-World Warblers, numbering one hundred species, confined exclusively to the Old World, with the exception of one species found in Alaska; (2) the Regulinæ, or Kinglets, of which three of the seven KINGLETS AND GNATCATCHERS. known species are found in the New World; (3) the Polioptilinæ, or Gnatcatchers, an American group containing about fifteen species, three of which are found in the United States.
The Kinglets and Gnatcatchers are active little birds, and constantly flit from limb to limb in their search for food. They are possessed of decided character, build remarkably beautiful nests, and some species are noteworthy songsters.
