At first glance, Hilty would be dealing possibly only with race delicata of P.plumbea and three possible races of subvinacea (peninsularis, zuliae, and purpureotincta). Possible race difference of iris color in the Brazilian ranging birds? In the zone of the shot it should be pallescens of the Plumbeous and race bogotensis of subvinacea I think.
