A small, energetic, gray-and-white bird that tends to waggle its long tail. Typically feeds low in dense scrub. Endemic to Cuba and offshore islands. Calls include a repeated “da-JIP,” a rapid squeaky “ji-ji-ji-ji-ji,” and a more classic gnatcatcher “zheee.” Note white face outlined with a thin black line, which readily distinguishes Cuban from Blue-gray Gnatcatcher.
