| | The Gyrfalcon - Potapov, Eugene; Sale, Richard - Yale University Press |
 | | Drawing on extensive research and travel to every country within the range of the Gyrfalcon, Eugene Potapov and Richard Sale delineate a new map of the bird’s range, conclude that the Gyrfalcon is more adaptable than previously thought, and restore the traditional Linnean scientific name of the species, Falco gyrfalco. |
 | | The authors also reveal that Gyrfalcons, for much of their lives, are true stenophagous raptors, a rarity not only among raptors but among all birds. |
 | | Elegantly illustrated with many photographs and line drawings, this is an essential volume for ornithologists, ecologists, wildlife rehabilitators, falconers, and all others fascinated by birds of prey. |
