Leiothlypis celata

The Orange-crowned Warbler is a small, mostly olive-green warbler with a thin bill, a faint eye-line and no distinct wingbars. Its orange crown patch is usually concealed and is rarely useful for identification. Birds from Pacific populations are generally brighter yellow than those farther east. The species searches for insects in shrubs and low vegetation but also takes nectar, sap and fruit. It usually nests on or close to the ground.
