CATALOGUE OF CANADIAN BIRDS. 721 



July 29th, showed that the southern migration had commenced. 

 We found an empty nest 30 miles below Dawson and heard that 

 the birds bred near Fort Yukon. Although robins were by no 

 means common at Caribou Crossing, I found, on June 25th, 13 

 empty nests, most of them evidently built that year and four 

 empty nests of the Alma thrush, in a small patch of spruces. The 

 red squirrels which lived in a hollow tree near by probably knew 

 of the location of most of these nests. Osgood took a well grown 

 young robin here on June 26th. {Bishop.) 



Breeding Notes. — This species nests at Scotch Lake, N.B. 

 from April to August. Four broods have been hatched in one 

 nest in one season. The nest always has earth in its composition 

 and is lined with leaves of grass; eggs three to five; I have known 

 the birds to move the eggs from one nest to another when the 

 first place had become too public. The period of incubation is 

 ten or eleven days and the young stay in the nest fourteen days. 

 {W. H. Moore.) Nests are placed on stumps and fences, in sheds 

 and around buildings and in trees almost from the ground to 50 

 feet up in large trees. The nest is made of grass with a bed of 

 mud and a lining of grass. Eggs taken at Ottawa in April, May, 

 June and July. (Gameau.) Nest very bulky, composed of vege- 

 table matter, leaves, moss, stems and weeds, grass, hair and wool; 

 inside is a neat cup of mud lined with fine vegetable matter; eggs 

 five of a rich greenish blue colour. No markings or spots. {G. R. 

 White.)
