While attaching GPS transmitters to Ferruginous hawks in the summer of 2014, Jesse Watson and Cam Nordell encountered a number of composed, charismatic male Ferruginous Hawks, like those pictured below. Typically, a male Ferruginous Hawk eye color will range from a light brown to a fairly dark brown. Interestingly, in many raptor species, a keen observer will often be able to detect a change in eye color with age.
During the attachment of the last transmitter of the summer Cam and Jesse encountered a particularly spectacular eye color in one individual. Below you can see the fantastic golden eye color of this particular male.
If you look really closely you can actually see Cam and Jesse in the reflection of his retina. It takes a brave researcher to meet the steely gaze of one of the Canadian Grasslands top predators, but it was a fitting end to the 2014 Ferruginous Hawk transmitter attachment season.
