PROCEEDINGS OF THE 



Horned Grebe — Colymbus auritus. During the fall of 1908 

 very abundant on the river at Holmesburg, in rather large 

 flocks, sometimes fifty or more seen at one time. 



Loon — Gavia immer. An adult shot on the river at Tacony 

 in the fall of 1903, and mounted by a local taxidermist. One 

 at Queen Lane Reservoir May 10, 1914 (Poole). The Red- 

 throated Loon I mentioned in 1903 was found in a gill-net above 

 Torresdale.* 



Herring Gull — Larus argentatus. Seen on the Diamond 

 Street Reservoir in Fairmount Park in 1910, 1912 and 1913, 

 between November 6 and 12 and until April 15 or May 1 

 (Poole). 



Ring-billed Gull — Larus delawarensis. From my old notes 

 an adult seen February 22, 1895, in the river off the mouth of 

 the Pennypack, 



Bonaparte's Gull — Larus Philadelphia. Four seen on the 

 Diamond Street Reservoir April 16, 1914 (Poole). Although 

 this gull has not been observed by me, it doubtless occurs regu- 

 larly during migrations, and seems to be known to many of the 

 river fishermen. 



Merganser — 'Mergus americanus. Found on the Diamond 

 Street Reservoir from 1910 until 1914, arrives November 1 to 

 14 and leaves May 1 to 9 (Poole). 



Red-breasted Merganser — Mergus serrator. About 1898 ? 



1 noted a flock on the river off Torresdale, and near this same 

 locality Mr. Miller reported a small flock February 1902. 



Hooded Merganser — Lophodytes cucullatus. None seen killed 

 on the river since 1885, prior to which time abundant (Smith). 

 A pair on the Pennypack near La Grange November 21, 1905 

 (Miller). 



Black Duck — Anas ruhripes. Several times seen along the 

 Pennypack above Crystal Springs. Two near Vereeville in late 

 June 1915 (Miller). 



Green- winged Teal — Nettion carolinense. One in a ditch at 

 Aramingo, October 1912? (Miller).
