George Guelph's Migration Notes. 



Mr. Guelph's scientific survey of 

 wildbird migration on the shores of 

 Lake Ontario follows: 



"To those who love the birds simply 

 from an aesthetic standpoint, to the 

 student who wishes to become more 

 familiar with the birds, or to the nat- 

 uralist desiring to make a scientific- 



study of the mysteries of bird migra- 

 tion, there is no better vantage point 

 than along the shore of Lake Ontario. 

 It is the main line of flight, the aeriai 

 highway of both land and water birds 

 in going to and returning from their 

 nesting grounds to the north. Some 

 species of land birds fly directly 

 across the lake, but the great bulk of 

 them follow closely along the shore. 

 In the Spring their flight is from West 

 to East, and in the Fall it is the re- 

 verse. 



"There are over two hundred spe- 

 cies of birds which may be looked 

 for regularly along the lake during 

 the time of migration, besides about, 

 twenty other species which may oc- 

 cassionally be found, and twelve 

 which have been recorded but a few 

 times, and are very rare. Then, also, 

 there is always the possibility of find- 

 ing something new. 



There is but a short period between 

 the time when ice first begins to show 

 signs of breaking up in the Spring 

 and the freezing again in the late Fall 

 but what some species of birds are 

 migrating. Hardly have the late 

 Spring migrants all passed north be- 

 fore some species are beginning to 

 return on their southern journey. 

 The past Spring the Loons were still 

 seen on the lake up to the fifteenth 

 of June. The bulk of the Ring-billed 

 and Herring Gulls did not leave until 

 about the twentieth of June. By the 

 first of July the Bronze Grackles were 

 beginning to be seen in small flocks, 

 and by the eleventh the Barn Swal- 

 lows were gathering in the marshes 

 at evening to roost. Most of the 

 young Red-winged Blackbirds had be- 

 gun to leave the marshes by the fif- 

 teenth. As early as the seventeenth 

 of July the Black-crowned Night 

 Herons began to appear, and by the 

 twenty-third they were seen daily.' 

 They usually continue to straggle 

 along until the latter part of Septen>
