DELAWAKB VALLEY ORNITHOLOGICAL CLUB. 45 



Colymbus auritus. Horned Grebe. 



Common on (lie Delaware during the fall and winter. Gener- 

 ally sliy and seldom ascending creeks beyond tide-water. 



Podilymbus podiceps. Pied-billed Grebe. 



A number were observed on tlie Delaware during November, 

 1895. It is most frequently seen on the Rancocas, Pennypack 

 and Neshaminy creeks and is shot at by gunners whenever an 

 opportunity is offered. The mill pond at Bristol is also a favor- 

 ite resort for these birds. Mr. Miller states that all the "Hell 

 Divers" seen by him, that were shot on the river, proved to be 

 this species; though he thinks it likely that the former species 

 is often killed as it is confused with this by gunners. 



Gavia iviher. Loon. 



This species has frequently been seen on the Delaware, during 

 November especially, but they are shy and usually keep well 

 out in the channel. A number of years ago several were seen 

 together at the mouth of the Pennyjiack creek, though they are 

 usually solitary. One killed on the river at Frankford in the 

 fall of 1902 {Miller). 



Gavia lumme. Red-throated Loon. 



Apjjarently more abundant than the preceding. At times as 

 many as a dozen are seen together. Not long ago one was re- 

 ported as taken in a fish-net. 



Ui-ia lomvia. Brunnich's Murre. 



Mr. J. H. Reed has observed a large flock of these birds on 

 the Delaware opposite Beverly, N. J., December 15 and 16, 

 1896 (see Auk, 1897, p. 202). The rather imperfect accounts 

 or descriptions submitted to me by gunners point to the occur- 

 rence of individuals occasionally during the winter, and I have 

 one in my collection killed at Byberry, January 11, 1901. 



Stercorarius pomarinus. Pomerine Jaeger. 



A rare straggler, one specimen secured by Mr. Chas. Vansciver 

 opposite Andalusia, October, 1898, now in the D. V. 0. C. col- 

 lection at the Academy of Natural Sciences. 



Larus argentatus. Herring Gull. 



Common winter resident. They seldom wander far from the 

 main course of the river, only occasionally following the smaller 

 creeks for short distances. Mr. W. L. Whitaker secured one
