I handled Khap, a gyrkin, as a 3-degree and as a 2-degree. We also had a couple of gray gyrkins (they also come black and white, depending on latitude) that we weren't allowed to fly because they were confiscated evidence. Once the legal case fell through, another guy got to fly Khap at a game, my Firstie year. Summit, a tiercel, was the team star. Temujin, a tiercel I also handled, was one we had successfully bred (a first in history). "Gyrkin" is a male, and the female is called “gyrfalcon”. "Tiercel" (as opposed to "falcon") also indicates a male. It means "one third smaller" which the males are.
