DIVING BIRDS 



10. Pacific Loon. Gavia pacifica. 



Range. — Western North America along the 

 coast chiefly, breeding from Alaska south to 

 British Columbia. In winter, south along the 

 coast to Mexico. 



This species differs from the Black-throated 

 only in the tint of the head reflections. The 

 habits are the same as those of the other members 

 of the family. They lay two eggs of a greenish 

 brown or greenish gray hue with black spots. 

 Size 3.10x1.90. Data. Yukon River, Alaska. 

 June 28, 1902. Nest of rubbish on an island;

11. Red-throated Loon. Gavia stellata. 



Range. — Northern parts of North America, 

 breeding from southern Canada northward in the 

 interior on both coasts. South to the middle por- 

 tions of the United States in winter. 



This is the smallest of the Loon family, being 

 twenty-five inches in length. In plumage it is 

 wholly unlike any of the other members at all 

 seasons of the year. In summer the back, head 

 and neck are gray, the latter being striped with 

 white. A large chestnut patch adorns the front 

 of the lower part of the neck. In winter the 

 hack is spotted with white, whereas all the others 

 tie unspotted at this period. The nesting habits are 

 identical with the other species; the ground color 

 of the two eggs is also the same. Size. 2.00 x 1.75.
