278 BIRDS. 



6. Mergus americanus. American merganser. — Michigan: This 

 is a common migrant and summer resident, breeding north of latitude 

 44°. 



One was seen near the end of Sand Point in the water of the bay 

 July 11. and another was in Turtle Bay on the south side of the 

 Point on July 18. The nest of this species was not found by our 

 party, but Mr. Edward Arnold* found it nesting on North and Stony 

 Islands. 



7. Lophodytes cucullatus. Hooded merganser. — Michigan: 

 Common migrant and summer resident, breeding north of latitude 

 44°. 



A small flock was seen in the rushes at the extreme end of Sand 

 Point on August 12, and a female was seen on Long Lake near the 

 end of the Point on June 24. The fisherman told us that the species 

 was very common at the Point both in the spring and fall, and that 

 it breeds on Charity Island. 



8. Anas platyrhynchos. Mallard.— Michigan: Common migrant 

 and summer resident: breeds throughout the state in suitable lo- 

 cahties. (On North Island, May 12, 1903. Arnold, loc. cit.) 



A flock of eight was seen flying near the end of Sand Point on June 

 14, and no doubt bred in the wet marshes somewhere in the vicinity. 

 The fishermen told us that it is abundant at Sand Point and Rush 

 Lake in spring and fall. 



9. Anas rubripes. Black duck. — Michigan: Common migrant 

 and summer resident, breeding in suitable marshes inland, as well as 

 along the Great Lakes. 



A flock of ten was seen June 14 near the end of Sand Point, and 

 single birds were seen after this in the grass}^ swamp that bordered 

 the bay. At Rush Lake they were common after August 10, and 

 one was seen on Stony Island on July 12. On June 15, two females 

 were seen to fly up from a wet grassy marsh near the end of the Point. 

 These birds circled about the marsh several times and then lit near 

 the spot where they were flushed. Later other birds were seen with 

 broods of young that were unable to fly, and these seemed to feed 

 among the islands of rushes and tall grass near the end of the Point. 

 After the young became large enough to fly we often saw them flying 

 across the Point to Turtle Bay on the south side, where they seemed 

 to feed on the wild rice, generally returning to spend the day in the 

 shelter of the rush islands. At Rush Lake the crop and stomach of 

 the single bird taken was found to be full of the roots of the wild 

 celery, and the shallow water where the ducks fed was covered with 

 the plants which had been pulled up, only the roots being eaten.
