o6 Loomis on Birds of Chester County, South Carolina. \ x*r\\ 



August i the Northern Phalaropes appeared as reported. A 

 Pomarine and a Parasitic Jaeger were taken, and a second speci- 

 men of the latter seen. There was a succession of California 

 Murres, individuals and small parties in single file, passing 

 down the coast, not nearer than a mile to the land, all the time 

 I was out on the Bay, which was during the forenoon and mid- 

 day. There was an equally great flight of Marbled Murrelets. 

 They came rapidly from up the coast and disappeared to the 

 southward. They flew usually in couples. There were young 

 birds as well as old. Not more than half a dozen were seen on 

 the water. The adults on the water took wing readily, but not 

 so the hornotines, which dived to escape pursuit. The same 

 was found true later in the Pigeon Guillemot. The young 

 seemed to lack wing power, one Guillemot actually fell back 

 into the water after getting partially under way. Such incidents 

 afford a fair key in some cases to the seeming prior occurrence 

 of young birds in the southward movement (the weak-winged 

 drop out of the race), and emphasize the fact that departure 

 from breeding grounds is the true criterion by which to deter- 

 mine the order of migration in the young and old. Dark-colored 

 Heermann's Gulls outnumbered the adults, proving an influx in 

 this species from another locality. 



August 2, as I have stated, large numbers of Northern Phal- 

 aropes passed southward. Several Pomarine and Parasitic 

 Jaegers were observed. In the California Murre and Marbled 

 Murrelet there was a falling off, there being but slight move- 

 ment in either. On the 4th occurred another wave of California 

 Murres and the passage of Shearwaters described under deflected 

 migration. Several Belted Kingfishers were noted on the 5th 

 occupying rocks where the surf was not heavy. As only one 

 had been seen previously about the Bay their presence was 

 imputed to migration. The morning of the 6th many Pigeon 

 Guillemots were found on the water just beyond the kelp. 

 Most of them wex - e adults. There had evidently been a move- 

 ment during the night, for before this only six had been noted, 

 and those birds-of-the-year during the latter half of July. Quite 

 a number of Dark-bodied and Pink-footed Shearwaters were 

 observed some three miles out from land. All were heading 

 southward. In the middle of the day, flocks of Gulls passed
