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.
The map below shows hotspots along our birding trails where you might see this bird.
