Sclater's antwren is a small understory antbird named after the British ornithologist Philip L. Sclater. It often forages in mixed-species flocks, where its quick movements and thin, high-pitched trills give it away. The species shows marked sexual dimorphism, with darker, more contrasting males and warmer-toned females. It is considered of low conservation concern but depends on intact lowland rainforest.
