* LOON. Oavia immer. 



A single individual was observed on Pelican Lake, eastern Cherry County, 

 October 12, 1915. 



* FRANKLIN GULL. Larus franklinii. 



This species was seen in summer on only three occasions : One at Duck Lake, 

 eastern Cherry County, June 5 ; 4 on Enders Lake, Brown County, June 13 ; 

 and 4 at Clear Lake, Brown County, June 14. 



A single individual was seen at Shoveller Lake, eastern Cherry County, Octo- 

 ber 8 ; and 6 on Twin Lake, Brown County, October 11. 



* RING-BILLED GULL. Larus delawarensi.s. 



A flock of 11 was seen on the south shore of Dewey Lake on June 4, and a 

 solitary' individual was noticed flying along the lake on the previous day ; 4 

 were noticed on Clear Lake, June 3, and 3 on the following day, but all these 

 may have been derived from the flock seen on Dewey Lake. No others were 

 noted in summer on any of the lakes. 



On most of the lakes in eastern Cherry County this gull was common, Octo- 

 ber 6 to 9, 1915 ; and we saw one on Blue Lake, Garden County, October 14, 

 and 7 on Crescent Lake on the same day. 



FORSTER TERN. Sterna forstert. 



The loud, harsh cries and dazzling white plumage of the Forster tern make 

 it a conspicuous object as it beats about over the lakes. It is fond of perching 

 on fence posts or stakes in the water, but descends to the ground not so 

 frequently as the black tern. 



This tern is common in summer throughout the region visited, except about 

 the lakes at the head of the North Loup River and the lakes of Garden and 

 Morrill Counties. It is most numerous and generally distributed on the lakes 

 of eastern Cherry County, and there most abundant on Pelican Lake, where the 

 writer saw 40 on June 10. It was common at Dewey Lake from June 3 to 18. 

 We saw 6 on Clear Lake, June 4; 8 on Hackberry Lake, June 5; 6 on Rei 

 Deer Lake, June 8 ; 5 on Trout Lake, June 11 ; 11 on Big Alkali Lake, June 9 ; 

 and 4 on Molly Marsh, June 11. It was noted also at Watts Lake on June o ; 

 Wendler Swamp on June 10; at the easternmost of the Sweetwater Lakes, 

 June 12 ; on South Cody Lake, June 1 ; on Clear Lake, Brown County, June 14 ; 

 Willow Lake, Brown County, June 14 ; and West Twin Lake, near the head of 

 the North Loup River, June 16. It was abundant at Moon Lake, Brown 

 County, where 24 were seen on June 13. The only lakes in Garden County at 

 which this tern was noted were Jones Lake, where 4 were seen, and Beaver 

 Lake, where 7 were observed, all on June 21. 



Five were seen on Dewey Lake, eastern Cherry County, on October 7, and 

 2 others on Pelican Lake, October 12, 1915. 



* COMMON TERN. Sterna hirundo. 



A single individual at Dewey Lake on June 5 was the only individual noted.
