Until recently, the best illustration of the Forest Owlet was this one, which appeared in The Scientific Results of the Second Yarkard Mission, published in 1891. The illustration has several inaccuracies:  the cheek patches are too dark and the breast is too barred; the belly, lower flanks, and undertail coverts should be completely white, not marked; the bands in the wing should be whiter; and the bill should be larger.
