Diving speeds and angles of a gyrfalcon (Falco rusticolus)
An optical tracking device recorded the three-dimensional paths of 11 dives by a 1.02 kg gyrfalcon, trained to dive to a falconer. The dives started at altitudes up to 500 m above the ground and were inclined at angles of 17-62 degrees from the horizontal. The falcon controlled its speed during the dives, rather than simply falling from the sky, and the dives had three phases. During the first ...
متن کاملSouthern Extension to the Breeding Range of the Gyrfalcon, Falco rusticolus, in Eastern North America
We report the observation of four gyrfalcon (Falco rusticolus) nests and several adults south of the previously recognized southern limit of the species’ breeding distribution in eastern North America. Our southernmost observation extends the known breeding range approximately 400 km to the south. The northern forest tundra biome could delineate the southern limit to the breeding range of the g...

متن کاملGenetics of plumage color in the Gyrfalcon (Falco rusticolus): analysis of the melanocortin-1 receptor gene.
Genetic variation at the melanocortin-1 receptor (MC1R) gene is correlated with melanin color variation in a few reported vertebrates. In Gyrfalcon (Falco rusticolus), plumage color variation exists throughout their arctic and subarctic circumpolar distribution, from white to gray and almost black. Multiple color variants do exist within the majority of populations; however, a few areas (e.g., ...
