Compare this to the previous two photos. It looks very different with darker gray underparts, more gray on the face, and a striking white iris. However, this isolated population from eastern Colombia and western Venezuela are currently included in the nominate subspecies along with birds from southern Colombia and northern Ecuador. Vocally they are also quite different. It wouldn't surprise me if it eventually gets described as a new taxon.
