The olive warbler is a small bird about 13 centimeters long. It lives in mountain coniferous forests and feeds on insects.
The olive warbler differs from true leaf-warblers in the structure of its skull and wing coloration. It is beneficial to the forest because it eats harmful insects.
Immature form that undergoes metamorphosis before adulthood.
