Audubon's Caracara 



362. Audubon Caracara. 

 Polyborus cherirvay. 



Range. — Southern border of the United States 

 south to South America. 



Range. — Southern border of the United 

 States south to South America. 



A strikingly marked blackish and whitish 

 species, much barred on the fore back and the 

 breast, with the head and throat largely white, 

 except for a black and somewhat crested 

 crown. They are numerous in southern Texas 

 and also in the interior of southern Florida, 

 where they are resident. They build bulky, 

 but shabby nests of sticks, weeds and grass, 

 piled into a promiscuous heap, generally locat 

 ed in bushes or low trees. Their two or three 

 eggs have a ground color varying from buff to 

 bright cinnamon, and are dotted and blotched 

 with all shades of brown and umber. On the 

 whole, these eggs show a greater diversity of 

 markings and ground color than those of any 

 other species. Size 2.50 x 1.80. 



363. Guadalupe Caracara. Polyborus lutosus. 



Range.- — Gaudalupe Island and others off Lower California. 



This species is somewhat like the preceding, but the plumage is duller, and 

 the coloration more uniform. Their nesting habits and eggs do not vary essen- 

 tially from those of Audubon Caracara. Mr. John Lewis Childs has a set of two 

 eggs taken June 8, 1896, on Santa Anita Island, by Coolidge and Miller. The 

 nest was made of sticks and situated in a giant cactus. The eggs are slightly 

 brighter and more clearly marked than any of cheriway that I have ever seen.
