Zeledon’s Antbird (Hafferia zeledoni)


French: Alapi de Zeledon German: Panamáameisenvogel Spanish: Hormiguero de Zeledón

Myrmeciza zeledoni


, 1909,

Guayabo, Costa Rica


Until recently considered conspecific with H. immaculata, but treatment as separate species supported by analysis of morphology, biometrics and vocalizations#R; differs in its larger (usually concealed) white shoulder patch (2); darker and duller crown in female (1); slightly longer bill (effect size 1; score 1); faster-paced song (at least 2) with more, shorter notes (at least 2). Both races originally described in same publication, on same page; zeledoni awarded priority by First Reviser#R. Race berlepschi previously listed as macrorhyncha, when species was treated in Myrmeciza with Sipia berlepschi, which has priority. Two subspecies recognized.
