386 MICHIGAN SURVEY, 1908. 



Stations : Eock Harbor, Rock Ridge Clearing, II, 3. 



Washington Harbor, Clearings, I, '04; Open Forest, II, 

 '04; X, '04. 



Breeding: July 11, nest with setting bird. 



Migration : September 6 to 21 on. " The residents reported large flocks 

 in October. 



This bird is rather rare, considering the island as a whole, but. occurs 

 in limited numbers wherever favorable conditions exist. The clearings, 

 both natural and artificial, at Eock Harbor afforded suitable habitats, 

 and at this place most of the Robins were found. At Siskowit they were 

 reported by the light-house keeper as occasionally nesting on Menagerie 

 Island and at the large clearing near the end of the bay (VII, '04) a 

 few were observed September 9 and 10. These latter were probably 

 migrating. They were regular nesters at Washington Harbor, the clear- 

 ings and other changes brought about by the agency of man, furnishing 

 conditions better suited to their needs than the balsam-spruce forest 

 which covered the island. Our observations at this latter point were so 

 late in the season that no nests or young birds were found, but the resi- 

 dent at the club-house (I, '04) and also on Washington Island (X, 04) re- 

 ported that the birds nested at both places during the latter part of 

 June. Only scattered individuals were observed at the club-house until 

 September 6, when the real migratory movement commenced. 



Breeding Notes: A nest with the female setting upon it was found 

 July 11. It was situated in a small birch tree on the edge of a clearing 

 on one of the rock ridges along the trail to McCargoe Cove (II, 3). The 

 nest was placed about fifteen feet from the ground. Several pairs of 

 these birds were observed at similar locations and probably nested 

 wherever found. 



113. Sialia sialis (766). Blue Bird. 



Range: Eastern United States to the eastern base of the Rocky 

 Mountains, north to Manitoba, Ontario and Nova Scotia, south in winter 

 from the middle states to the Gulf States and Cuba. 



Stations : Washington Harbor, clearings and burned area, I, '04. 



Breeding : Found near nest August 18. 



Migrating : August 22 to September 12. 



The Blue Bird is a rare summer resident on the island. None of this 

 species were observed during our stay on the island the year previous, 

 and the few families which came to the clearing at Washington Harbor 

 were the only ones observed throughout this season. 



Breeding Notes: A nest of this bird was found in a birch stub near 

 the edge of the third clearing. It was located in a Downy Woodpecker's 

 hole about fifteen feet above the ground. On this date, August 18, the 

 young had left the nest, but still kept in its immediate vicinity.
