The Bullock Oriole 



one wherein summer rains play little or no part. Nesting, as it does, 

 from the highlands of Mexico north to British Columbia, the Bullock 

 Oriole shelters in a great variety of host trees, mesquite, willow, sycamore, 

 cottonwood, oak, pine even, not to mention every conceivable variety of 

 the larger shrubs. 



Because the variation in construction is so infinite, five examples 

 from the M. C. O. collections, taken in California, must suffice: 



Nest Ki6o*\ 6 , lashed throughout to descending twigs of cottonwood; 

 is composed of horse-hair of three shades, with slight admixture of string, 

 and is decorated sparingly with small white feathers. Lining, confined 

 to bottom third, of white feathers. Measures 7 inches deep by 4 wide 

 over all. Inside depth, from lowest portion of brim, 2> l A inches. Opening, 

 2}4 by 3. Weight with included twigs exactly half an ounce.
