Horornis diphone | Japanese bush-warbler

Introduced

Other Names: uguisu, ウグイス

The uguisu or Japanese bush warbler is less than 6-inches long with drab brown feathers and pale eyebrows. A secretive bird, they hide in dense foliage and so, more often than not, the average bird watcher will hear this bird rather than see it. It has a loud sustained whistle followed by several quick notes that “say” itʻs name (“uguisu!”). Birds usually sound closer than they really are.
