Juveniles display a more subdued version of the adult plumage, with a slightly browner tinge to the black areas and less distinct white markings. Both sexes appear similar, although females may exhibit slightly less vibrant plumage. Key identification features include the bird's small size, which measures approximately 9 to 10 centimeters in length, and its compact build.
When comparing with similar species, the Black-and-white Tody-Flycatcher may be confused with other small flycatchers and tody-tyrants. However, the absence of vibrant colorations such as yellows or greens, combined with its unique monochrome palette, helps distinguish it. In flight, its silhouette is characterized by short, rounded wings and a slightly rounded tail, typical of many small forest-dwelling flycatchers.
