In early falconry, a man no longer young enough to fly his own bird wound up toting the wooden frame on which live hawks were carried. It was called a “cadge,” pronounced “codge.” That’s where we got “old codger.”
The eyesight of a hawk is 8 times as powerful as a human’s.
A hawk’s talons are its main weapons.
85–90% of the Red-tailed Hawk’s diet is composed of small rodents.
The American Kestrel is the smallest North American hawk and feeds mainly on mice and insects.
Many birds call out warning alarms of two kinds: One sound signals danger in the air, such as a hawk. Another, danger on the ground, such as a fox.
The only bird of prey that sings is the South African Chanting Goshawk. None other even hums.
In the language of the falconers, any “falcon” is female. The male is a “tiercel,” a word that relates to three. The bird is said by some to have been so called because it was one-third smaller than the female, by others, because a third egg in a nest was believed to be smaller and to produce a male.
A falcon sees less with both eyes focused together than with either eye focused alone.
The first animal to be listed as an endangered species was the peregrine falcon.
NOTE: The success of recovery programs begun in 1972 allowed the declassification of the peregrine falcon as a federally endangered species in 1999. Although the bird of prey remains federally protected under the Migratory Bird Treaty Act and will be monitored until 2015, the survival of the peregrine falcon marked the most dramatic success of the Endangered Species Act.
