16 AUKS, MURRES, AND PUFFINS 



Mr. Preble, who found these murrelets common at Neah Bay, Wash- 

 ington, reports that they were almost invariably seen in pairs and 

 that they were difficult to approach, as they dived at the slightest 

 alarm.

Eggs. As found by Dr. Dall, 2, at the 

 bottom of a hole under the rocks near the water's edge. 



In Alaska Mr. Nelson found the pigeon guillemot one of the most 

 abundant of the larger water birds, occurring wherever the coast 

 was bordered by bold headlands or where there were precipitous 

 islands. He says that their bright red legs and white wing patches 

 make them very conspicuous. They are graceful swimmers and 

 have the amusing habit of putting their heads under water and pad- 

 dling along their headless bodies. 



Mr. Bryant, who has watched them at the Farallones, says that 

 when at rest they squat like ducks on the rocks. Before brooding 

 begins they often sit in groups, and when disturbed stand up, open 

 their bills, and salute each other or their returning fellows with a 

 whistling cry.

30a. Uria troile californica (Bryant). CALIFORNIA MURRE.
