| Bird species include peregrine and gyrfalcon, eagles, ruffed grouse, rock ptarmigan, loons, ducks and swans. |
| Longwings are falcons, such as the peregrine, the saker, and the gyrfalcon. |
| The gyrfalcon is the best-proportioned and most active member of the Falcon tribe. |
| The gyrfalcon is the speed-king among birds, but the hoary bat is faster still. |
| 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. |
| Four characteristic birds of prey include the snowy owl, gyrfalcon, osprey, and rough-legged hawk. |
