a truly gregarious disposition. Unlike the Horned Grebe, none were 

 seen on the main lake, while on the other hand none of that species 

 were found in the ponds. At this time the birds were by no means 

 shy, and being so constantly in evidence were the source of some 

 trouble to the observer looking for other species. A decrease in their 

 numbers was noticeable through October, becoming more marked as 

 the Horned Grebe increased in abundance, while the last record was 

 made on November 14, although the probabilities favor a somewhat 

 later date as the actual time of final departure. 

 4. Gavia imber. Loon. 



"A few of these birds are seen on the bay every spring and fall, 

 but they are never common. I observed one individual as late as 

 May 31 (1896), while September 25 (1894) is my earliest fall record " 

 (Bacon). Mr. Simpson reports the species as having been observed 

 in April and November of 1902 and 1903, and notes that a specimen, 

 still in winter plumage, was shot at Crystal Point on April 25, 

 1902. Curiously enough, no Loons were seen in the spring of 1900 

 until May 4, when two individuals were observed flying over the bay 

 together. In the fall the species was more numerous, arriving Octo- 

 ber 6, and was noted at intervals during that month and the next, 

 single birds being recorded from the bay or lake. On November 12 

 a gunner picked up a Loon on the shore of Misery Bay near our house- 

 boat, and brought it to us alive. It was practically helpless on the 

 flat surface, but quite vicious, striking savagely with its powerful beak 

 when teased, and uttering its peculiar reverberating cry. Upon skinning 

 it proved to have been wounded and partially disabled. The last 

 record was made on November 18, when one was seen on Misery Bay 

 off Crystal Point, and watched for some time while feeding. It doubt- 

 less remains as long as there is open water in the bay. Occasionally 

 one is caught in the fishermen's nets. A fine specimen in the Car- 

 negie Museum, dated April 25, 1903, was taken in this way. 



[ Gavia arctica. Black-throated Loon. 



Given by Mr. Lynds Jones [Birds of Ohio, 1903, 26 J as a casual winter visitor in 

 Ohio, where a number of specimens have been taken since that recorded by Dr. J. M. 

 Wheaton, which was captured near Kelley's Island instead of on Sandusky Bay. 

 This is a boreal species, seldom reaching the United States in its winter dispersion.] 



5. Gavia lumme. Red-throated Loon. 



Although Dr. Warren states (Birds of Pennsylvania, 1890, 8), pre- 

 sumably on Mr. Sennett's authority, that " this bird is often met with,
