"^"igos^^J EiFRiG, The Spring Migration, 1907, at Ottawa, Out. 7 



That the nesting of the birds, whose coming had been so delayed, 

 was also somewhat postponed, is almost self-evident. In fact this 

 was not only caused by lateness of arrival, but also by the lack of 

 cover in trees and swamps. Thus the Robins and Redwings, 

 having been here even earlier than usual, in many cases commenced 

 nest building much later, waiting no doubt for the leaves to come 

 out and the cattails to grow to screen their nests from view. Per- 

 haps for the same reason more Robins put up their establishments 

 on houses, under verandas, over doors and windows and like situa- 

 tions, than I have ever seen before. 



The following list will serve to further illustrate some of the points 

 made above. It is not by any means a complete list of all species 

 to be recorded here. Birds like Redpolls, Crossbills, many ducks, 

 hawks, etc., are omitted for apparent reasons. Some species, like 

 the Brown Thrasher, the Olive-sided Flycatcher, the Black-billed 

 Cuckoo, Osprey, etc., were not seen by me till June or July, after 

 being installed in their breeding places for some time.
