CALIFORNIA WATER BIRDS. 3 



waters were seen passing down the coast. The move- 

 ment was still in progress at the time of my return to 

 the land. As in the case of the migrants early in the 

 season, they followed the shore-line. Appearing from 

 the northward, singly and in companies, they passed 

 swiftly by and disappeared to the southward. At Point 

 Pinos the inner edge of their path of flight was not more 

 than half a mile from the shore. Three males and a 

 female were secured. Accompanying the Black-vented 

 were a few Dark-bodied Shearwaters. A half a dozen 

 were identified, one of them being captured. 



On the 18th I was again far enough out from land to be 

 in the path of migrating Shearwaters, but only two were 

 observed, a Black-vented and a Dark-bodied. Both were 

 heading southward. On the 20th, after a heavy gale, a 

 Dark-bodied Shearwater was shot as it was flying over 

 the bay about a mile offshore midway between the Lab- 

 oratory and Monterey. As I did not go out toward Point 

 Pinos it was not ascertained whether there was a move- 

 ment in progress. 



About fifty Black-vented Shearwaters were seen during 

 the forenoon of December 31st. They came from the 

 northward, straggling along at intervals, and without 

 pausing passed quickly out of sight down the coast. It 

 was clear and they kept well off from the land — from 

 three to five miles at Point Pinos. A female was the only 

 specimen taken. The organs of reproduction in this 

 bird were functionally enlarged, which was not the case 

 in the examples obtained on the 14th. 



January 2d two Black-vented Shearwaters were seen. 

 They were flying southward. No others were met with 

 between Dec. 31st and Jan. 10th, although trips were 

 made outside of the bay on six of these days. Much of 

 this time the weather was unfavorable for migration. A
