Males and females look alike; juveniles can be distinguished by their paler coloration and red-brown to muddy-gray eyes.[1] Adults have more red-brown[2] to red eyes.[3] Other distinctive features of juveniles include the lack of a white nape streak, and less noticeable black chest markings.[3] Summer often takes a harsh toll on plumage; the intense desert sun and prickly vegetation fade and damage feathers.
