THE EAGLE, KING OF BIRDS, AND HIS KIN Photograph by George E. Stone GALAPAGOS HAWKS HAVE NEVER LEARNED THE FEAR OF MAN The wild life of these Ecuadoran islands has evolved in almost complete isolation, and as a result has always been tame. The confidence which hawks have reposed in the human race has often been abused, but for some reason they are still outstanding in their fearlessness. The tree is a bursera, the small leaves of which are short-lived, leaving it bare most of the time. Its bark exudes an aromatic scent when it is brushed. The eggs of this group are moderate in size relative to the bulk of the parent, par ticularly when the larger species are con sidered. They have strong, heavy shells, usually with roughly granular surface. In some instances the eggs are plain white, bluish white, or greenish white, but in most there are markings of brown, which ap pear slaty where overlaid by a thin film of the calcareous shell. The eggs of most falcons are heavily spotted with reddish brown, being among the most handsomely and richly marked known. Many species exhibit considerable di versity in the extent and amount of mark ings, the eggs in some cases varying from plain white without markings to those that have the background completely obscured by a heavy wash of warm color.
