Once called the Long-billed Gnatwren, which was split along with the Chattering Gnatwren. From back with nesting material. |
The Long-billed Gnatwrens in east Peru to northwest Mato Grosso, Brazil are now called the Chattering Gnatwren, because of vocal differences with the more widespread Trilling Gnatwren, and 'white spots on outer rectrices' (HBW). |
