I did not positively identify this species, although many terns were seen 

 daily. Mr, Alfred Eastgate tells me it nested at Kavanah Lake, Ramsey 

 County, in 1898. 



13. Sterna hinindo Linnseus. Common Tern. 



Bent, 1921, p. 133; a large colony at Stump Lake, June 15, 1901 ; p. 244; egg 

 dates, North Dakota, thirty-six records. May 31 to July 15. 



The skins of an adult and two young in the Museum of Zoology Collec- 

 tion were taken at Devils Lake, July 8, 1919, by Crystal Thompson. 



This species is an abundant summer resident\of the Devils and Stump 

 lakes region and the writer visited large colonies on sandy islands in both 

 lakes. The Devils Lake colony on July 15, 1920, contained only nests 'with 

 full sets, many of them fresh. Nearly all nests of the Stump Lake colony 

 had young, some able to fly, on July 25. 



14. Hydrochelidon nigi'a surinamciisis (Gmelin). Black Tern. 



CouEs, 1878, p. 656; a colony of this species was found breeding at Pembina in 

 June, 1873, and others were seen later nt the Mouse Rivtr. Coles, 1897, p. 39; Time 

 ;8. 1843, Audubon saw a black tern which, no douljt, bred there, at Fort Union, Wil- 

 liams County. 



A large flock, comprised of hundreds of both adults and young, was seen 

 at Lake Upsilon from July 30 to August 7, 1920. The species was seen at 

 Devils Lake, May 23, 192 1. It is an abundant summer resident in all suit- 

 able habitats throughout the state and feeds chiefly on small fish and' crus- 

 taceans.

1917, p. 6; tolerably common migrant, no records of its breeding except in Devils 

 and Stump lakes. Bailey, 1918, p. 175; records a visit to the colony noted above on 

 the bird rocks at Devils, Lake. Bext, 1921, p. 133; visited in June, 1901, a colony of 

 about seventj'-five pairs on an island in Stump Lake. 



A juvenile skin in the Museum of Zoology Collection was taken at the 

 Devils Lake colony on July 15, 1919. This was the last year this species 

 nested on Bird Island. Another juvenile in our collection was taken at the 

 Stump Lake Bird Reserve, June 23, 1919. This was collected by Crystal 

 Thompson, who also collected nests and birds for a habitat group in the 

 Biological Station Museum at Devils Lake. 



A set of two eggs collected j\Iay 30, 1896, at Sweetwater Lake, Ramsey 

 County, by E. S. Bryant, is in the [Museum of Zoology Oological Collection. 



It was a rare summer resident as late as 1918, when Crystal Thompson 

 found a small colony nesting on Bird Island. On July 15, 1920, I counted 

 thirty-three old nests and saw one adult bird. This colony left the lake per- 

 haps because of the scarcity of fish and because it was disturbed by campers. 

 On July 25, 1920, the colony on the Bird Reserve at Stump Lake was vis-
