Life Histories of North American Birds of Prey: Order Falconiformes. E-book. Formato PDF Arthur Cleveland Bent   -  Forgotten Books, 2017  - 

An attempt has been made to give as full a life history as possible of the best-known subspecies and to avoid duplication by writing brie?y of the others and giving only the characters of the subspecies, its range, and any habits peculiar to it. In many cases certain habits, probably common to the species as a. Whole, have been recorded for only one subspecies; such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the subspecies, which cannot be accurately defined in many cases.
