Profile of a Killer - Golden Eagle showing the rear talon known as the 'killing talon' that is driven into prey upon impact. In this case the eagle scavenged a rattlesnake and was content with his meal until the blackbirds sent him packing. Here he is having a bad hair day and looking very unhappy at the 3 red winged black birds constantly harassing him.
Additionally the 'boots' of the Aquila genus is visible clearly here as is the golden nape from which this species gets its name.
The golden nape and lighter coloration is indicative of an adult bird as was the dark tail with the marbling pattern and dark underwings that I observed when the bird took flight. Younger birds have the white rectangles and whitish tail band and tend to be darker overall with less gold on the nape
