ber. They preferred the dead brush of the burning and the low open 

 alders and birches along the road and clearings. 



50. Otocoris alpestris (474). Horned Lark. 



Range: Northeastern North America, Greenland, and northern parts 

 of the Old World ; in winter south in eastern United States to the Caro- 

 linas, Illinois, etc. 



Stations: Washington Harbor, clearing, I, '04. 



Migration: September 13 to 21. 



Large flocks of Horned Larks appeared at the first clearing early in 

 the morning of September 13. The birds continued to increase in number 

 for several days, and were found almost entirely at the first clearing, 

 which was considerably the largest. They were eminently birds of the 

 open, not even being found in the most open forest. They showed little 

 preference between the plowed ground and the grassy meadow, and fed 

 on insects as well as seeds. Little fear was shown, and when shot at 

 upon the ground they often rose up in a whirling flock and after circling 

 about the clearing would return to the same spot. It was a common 

 occurrence to see them rise suddenly, seemingly without cause, and fly 

 rapidly away only to wheel about and return to their old feeding 

 grounds after having gone a quarter of a mile or so. Occasionally Amer- 

 ican Pipits were seen in company -with them, but usually because the 

 feeding grounds of the two flocks overlapped. The first flocks numbered 

 from 30 to 50, but soon they grew to two or three hundred, the birds 

 being very gregarious at this time of the year and seldom found alone. 

 In a good series taken at random from different flocks the females seemed 

 to predominate. The birds were all highly colored, especially the males. 



51. Gyanocitta cristata (477). Blue Jay. 



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

 countries south to Florida and eastern Texas. 



Stations : Rock Harbor, clearing along Benson Brook, II, 1. Sis- 

 kowit Bay, Forest, V, 4; clearings, Y, 1. II, 2. II, 3. Ill, 5. 

 Washington Harbor, clearing, I, '04; Forest, II, '04. 



Resident: July 13 to September 20. 



Without doubt many of the Blue Jays winter on the island and none 

 were seen which showed any indications of even a local migration, either 

 from one part of the island to another or to the mainland. They were 

 fairly common in the swamps and along the rock ridges at Rock Harbor. 

 On July 13 several were seen in a tamarack swamp (II, 2) and a flock 

 numbering six or seven were found along a rock ridge (II, 3), feeding 

 in the mountain alders along the edge of the rock clearing. They were 

 also noted at Sumner Lake on July 26. At Siskowit they were only 

 occasionally met with, one specimen being taken on the trail to Sisko- 

 wit Lake (V, 4) August 15. At Washington Harbor they were very 

 common and were recorded nearly every day of our stay. The Blue 

 Jays preferred the dry open birch forest and cleai'ings or old burnings. 

 Occasionally they were found in the swamps and also in the balsam 

 forest along the river. It was, however, a bird of wide distribution and 

 was liable to occur in any habitat.
