Fan-tailed Warbler Basileuterus lachrymosus

The affinities of the monospecific genus Euthlypis are still unclear, although it is sometimes subsumed within Basileuterus, and some authorities have pointed to structural similarities with the Yellow-breasted Chat (Icteria virens). The single species, the Fan-tailed Warbler, is a distinctive bird found from northern Mexico south to northwest Nicaragua, with largely grayish upperparts, a black foreface, white lores and tip to the tail, and yellow underparts becoming white ventrally. Fan-tailed Warblers are inhabitants of submontane and lower montane forests from close to sea level to approximately 1800 m, always in areas with an undisturbed understory. Fan-tailed Warblers follow army ants, taking insects fleeing from the swarm, and they sometimes also follow Nine-banded Armadillos (Dasypus novemcinctus), for similar reasons.
