DUSKY, GRAY, AND SLATE-COLORED S23 



ail altitude of twelve thousand feet, yet he is by no 

 means rare along the lowlands. Pine, oak, cottonwood, 

 walnut, hick berry, and sycamore trees are his chosen 

 nesting sites, and on the horizontal limbs of these the 

 bulky cradle is constructed. Twigs, rootlets, weed stalks, 

 string, rags, and plant fibre form its walls, grotesquely 

 decorated with feathers, like those of the xlrkansas king- 

 bird. These last, waving rakishly in the wind, are quite

 Kingbirds cannot be doubted ; and though they are far

 content to live at peace with hawks and crows, Cassin 

 Kingbirds drive both these from their neighborhood by 

 an onslaught both fierce and speedy. For this they 

 have good cause, for crows are thieves and cannibals, 

 feasting on the eggs and young of smaller birds. 



The young Kingbirds, although born naked, soon

 are the young of the Eastern kingbird, called the tyrant. 

 Of the many broods of the latter that I have watched, 

 the process has ever been the same. Nor do they differ 

 greatly in any of their habits. The Cassin, sitting on a 

 fence or a weed stalk, flying out after a passing insect,
