incubate. Two or three eggs are laid, and they are noted for the heauty of their 

 coloration. On a ground color varying from light and dark cinnamon to reddish 

 and umber-brown, are specks, spots, blotches and cloudings of yellowish or reddish- 

 brown, bright chestnut, umber or claret-brown. The markings are variously dis- 

 tributed over the surface; in some specimens they are dispersed over the entire egg, 

 while in othersscattering or more abiindant at the smaller or greater half; occasional 

 specimens are found almost entirely unmarked. The sizes vary from 2.10 to 2.92 la

363. GUADALUPE CABACABA. Polyborvm hitosus Ridgw.— Geog. Dlst— 

 Guadalupe Island, Lower California. 



This is a much paler and browner colored species than the preceding. It was 

 and possibly is a resident of Guadalupe Island. From all accounts its general habits 

 are the same as those of Audubon's Caracara, and there is probably little difference 

 In its nesting and eggs.

 Dist.— Nearly cosmopolitan. In America from Alaska and Hudson Bay south to 

 West Indies and Northern South America.
