| Golden eagle, gyrfalcon and rough-legged hawks were also observed during the survey. |
| When only a streak of silver sky, with a shoal of little violet clouds, was left of the daylight the gyrfalcon gave up the chase. |
| The gyrfalcon is the speed-king among birds, but the hoary bat is faster still. |
| When we get there it doesn't look promising, but there are a few sops for me: a handful of curious seals, a gyrfalcon, and rafts of eider ducks. |
| The gyrfalcon is the best-proportioned and most active member of the Falcon tribe. |
| Longwings are falcons, such as the peregrine, the saker, and the gyrfalcon. |
