Old World Warblers: Sylviidae
Old World warblers encompass a variety of different species, as small as 3.1 inches (8 centimeters) long to as large as 9.8 inches (25 centimeters), weighing from 0.1 to 2 ounces (4 to 56 grams). Many species live eight to twelve years.
All Old World warblers have bristles at the base of thin, pointed bills that help them catch flying insects. The wings of species that migrate are long and pointed, whereas the wings of birds that remain within permanent territories are round and short.
Most of the birds in this family are dully colored in greens, yellows, grays, and browns.
