I 'JO Bin r. Summer Birds of Soitthurtftrn Saskatchewan. [oct* 



9, 1905, where they were nesting in a Large shallow bulrush slough. They 

 occupied an area approximately LOOO yards lone by 100 yards wide and by 

 counting tin* nests in an area 10 yards square, I estimated that there 

 were from 15,000 to 20,000 nests in the colony. Many oi the eggs that 

 we collected were heavily incubated and some of them were hatching at 

 that time. We visited this colony in 1906 but were disappointed to find 

 it entirely deserted, probably owing to the fact that the Blough had been 

 nearly dry earlier in the season when they were beginning to breed. We 

 found three other, smaller, breeding colonies in L 906 at Crane bake. Reedy 

 bake and Many Island bake, finding eggs as late as June "JO. 



S. Sterna forsteri. FORSTER's 1Vk\. bare. A few birds were seen 

 at Many Island bake on June IS. 1906, and on July two specimens were 

 taken here by Pr. bishop. This species is not recorded by Prof. Macoun 

 tart her west than Indian Head. 



0. Sterna hirundo. Common Tern. Common but nowhere very 

 abundant, bound breeding at all of the larger Lakes, principally on the 

 islands. Eggs were found on June 1 and 7. L905, on June 13, 11 and 15 

 and on July 0. 1906. 



Scattering birds were frequently seen near the creeks at Long distances 

 from the lakes. 



10. Hydrochelidon nigra surinamensis. Hi icx Tern. Common in 

 certain localities, particularly shallow BV, get water sloughs or wet meadow - 

 over which a number of these terns were generally to be seen hovering. 

 It was only in these shallow grassy sloughs that we found them breeding 

 where their eggs were laid on floating masses of dead vegetation. They 

 are late breeders. We did not find their eggs until June 24, 1906, when 

 several fresh sets were collected. 



ii. Phalacrocorax dilophus. Double-crested Cormorant. — Al- 

 though this species is recorded by Prof. Macoun as breeding at Crane bake. 

 I did not see it at all either season, but Pr. bishop reports finding four 

 nests, with from 1 too eggs each, on the island in Big Stick bake, on July 

 21, 1906. I visited this island on June 11 and 15, 1906, but no cormorants 

 were seen. No specimens were taken but they were undoubtedly of this 

 species. 



12, Pelecanus erythrorhynchos. American White Pelican. Com- 

 mon, blocks of pelicans were seen almost daily at Crane bake and at 

 big Stick bake, frequenting the islands, but 1 was unable to find them 

 breeding. The others were more fortunate for on July IS and 21, 1906, 

 they found 1 I nests on the island in big Stick bake. 4 with 1 egg and 10 

 with 2 eggs each, lather these birds are late breeders or their first nests 

 had been destroyed. A large flock oi pelicans containing at least 150 birds 

 was seen at Many Island bake on July 13, 1000. 



13, Merganser americanus. Amsrk w Merganser,— Uncommon. 

 One or two birds were seen by Mr. Job at Crane bake on June 15, 1905, and 

 we - w . .lock of 11 birds here on June 23, 1000. 



On the island in l>is: Stick bake on June 14, 1906, we found 3 ducks'
