276 BIRDS. * 



The facts seemed to show that the warblers cross the Bay nearer its 

 head, and that the sandpipers strike across nearer the mouth, probably 

 not only because they are stronger fliers but also because the best beaches 

 are nearer Lake Huron. The sandpipers seemed without exception 

 to follow the beach north and east and probably continue round the 

 end of the thumb, and from some point on the east coast fly down to 

 southern Ontario. 



The follo'^ing list gives the results of our work upon the ornis of the 

 region. Besides the collecting of specimens and the recording of ob- 

 servations, however, stomachs and parasites were saved in every case. 

 The former are reserved for future study, the latter have been reported 

 upon elsewhere in this volume by Prof. Shull. 



LIST OF SPECIES. 



1. Podilymbus podiceps. Pied-billed grebe. — Michigan: Common 

 as a migrant and locally common as a breeder throughout the state. 



On August 15, two were seen at Rush Lake a,nd three at Turtle Bay 

 on the south side of Sand Point, August 24. It was not found 

 breeding, although at Rush Lake and also on the Point the conditions 

 seemed favorable. "We were told by residents that it is very 

 abundant in the spring. 



2. Gavia immer. Loon. — Michigan: Common as a migrant and 

 locally common as a breeder throughout the state. 



One specimen was seen flying over Sand Point early in the morning 

 of June 16. This bird no doubt had a nest along the marshy shore 

 of Wild Fowl Bay. Mr. Frank Brackenbury, a fisherman, told us 

 that in the spring of 1908 more than twenty-five loons were found 

 in the pounds and entangled in the nets on one line of fish stakes. 

 It is well known that this species lives on fish which it pursues to a 

 great depth and is often caught on set lines as well as in gill and 

 pound nets. 



3. Larus argentatus smithsonianus. American herring gull. — 

 Michigan: Common as a migrant and locall}' common as a breeder 

 north of latitude 44°. 



The herring gull was first seen June 17, when about twentv-five 

 lit on the top of the fish stakes on the north side of Sand Point. 

 After this date it was seen here only occasionally until August 17, 

 after which it was common every day. On July 15, it was seen at 

 Stony Island, and at Oak Point four were seen on August 2, and 

 afterward occasionally during our stay near there. The fishermen 

 said that a few of this species breed each year on Little Charity Is- 

 land, a small rocky island about twelve miles to the north of Sand 

 Point. They also reported the species as very abundant both in
