The Brown Honeyeater is similar to the Dusky Honeyeater, Myzomela obscura, in size and shape, but this species is much darker brown and lacks the tuft behind the eye and the yellowish wing patches. It could also be confused with females or young birds of the Scarlet Honeyeater, M. sanguinolenta, or Red-headed Honeyeater, M. erythrocephala, but these are smaller with shorter tails, lack the eye tuft, often have a reddish face and have very different calls.
