356 MICHIGAN SURVEY, 1908. 



until nearly forced to for the sake of safety. Nearly all the smaller 

 woodpeckers protect themselves by dodging around the trees, but the 

 Pileated, possibly because of its large size, rarely attempts this, but 

 flies away with a rapid, iindulatory motion. When in full flight the 

 white in the wings is very striking and seems to catch the attention 

 when otherwise the bird might pass by unnoticed in the dark woods. 



39. Colaptes aiiratus liitens (412). Northern Flicker. 



Range: Northern and eastern North America west to the eastern 

 slope of the Rocky Mountains and Alaska. Occasional on the Pacific 

 slope from California northward. 



Stations: Rock Harbor; Spruce and Balsam Forest, I, 2-3. Tama- 

 rack and Arbor Yitae swamps, 1, 4. 

 Partial Clearing, I, 1 ; along Benson Brook, II, 1, II, 4. 

 Siskowit Bay, Forest V, 4; Old Burning, V, 9. 

 Washington Harbor, border of forest and open clearing, 

 I, '04. 



Breeding: A young of the year was taken July 31. 



While not a rare bird, it was not very abundant in the east end of the 

 island, undoubtedly owing to the scarcity of suitable timber to nest in. 

 Several individuals were seen, the first one on July 6 at the edge of 

 the balsams along the clearing from the light-house to the fisherman's 

 cottages at Rock Harbor (I, 3). They were occasionally noted in the 

 cedar swamp at the end of Tonkin Bay (I, 4), and also in the birch 

 forests near McCargoe Cove (II, 4). A young of the year was taken 

 July 31 in the balsam-spruce forest ( 1,3). 



They were rather scarce at Siskowit Bay probably because the timber 

 was mostly green balsam and spruce, as this bird prefers clearings and 

 burned areas where it can get larvae from decaying trees, or where 

 ant hills are abundant. The most favorable conditions existed at Wash- 

 ington Harbor where large clearings afforded the much coveted ants 

 as well as dead trees. At this point, therefore, the birds were very 

 common and continued to increase in number throughout our stay. 

 Many of these birds were found dead during September but I was 

 unable to determine the cause; it might possibly have been due to some 

 parasite. The keeper at the club-house told me that the birds con- 

 tinued to increase through October and that towards the end of the 

 season hundreds died, but he did not know the cause of their death. 

 The Flicker probably gathers at the southwestern end from all over 

 the island and possibly many come from the north shore, remaining 

 here where such favorable conditions exist, until cold weather neces- 

 sitates their journey onward. 



40. Antrostomus rovifcnis. (417). Whip-poor-will. 



Range: Eastern North America to the Plains, and from Latitude 

 50° south to Guatemala. 



Stations : Border of clearing, II, 1. 



One of these birds was heard calling in the edge of the clearings along 

 Benson Brook. 



41. Chordeiles rirniiiiaiiuft (420). Night Hawk. 



Range: Northern and eastern North America, west to the great 

 plains and central British Columbia, and from Labrador south through 

 tropical America to the Argentine Republic.
