66 THE BIOLOGICAL REVIEW. 



seem to feed on insects which they collect on the spruce 

 trees. 



Last summer I found two Kingfisher's nests ; in one there 

 were seven eggs* and in the other six. In one nest I found the 

 9 sitting, and in the other the cT', thus showing that the c? 

 assists in the duties of incubation. 



(December 20, 1892.) I have lately seen three specimens of 

 a rare bird, the Hudsonian Chickadee (Parus hudsonicus). It is 

 a little larger than the common species [Parus atricapillus) ; 

 the crown is dull black ; the upper parts, wings and tail darkish 

 slate color ; all the under parts the color of the breast of 

 the adult cT Sitta canadensis. I saw one near my place on 

 November 4, 1892, and two more about eight miles north of my 

 farm on November 8, 1892. And again, as I was driving past 

 the same place on December 10, 1892, I saw what I took to be 

 the same two birds on the same tree. I stopped my team and, 

 getting out of the sleigh, I had a good look at them, for they 

 were not at all wild, and allowed me to go within about three 

 feet of them. They seem to frequent the second growth pine 

 and spruce trees. 



So far I have not been able to collect any specimens. It is 

 snowing nearly every day here, and there is now very deep 

 snow, and this is most likely to be a very severe winter, and 

 probably the greater severity of the weather to the north has 

 caused a southern migration. 



Canada Jays (Perisoreus canadensis) have been very numerous 

 this winter ; they frequent dooryards and wherever they can 

 pick up any kind of food. Pine Grosbeaks are also numerous 

 and very tame and I have collected some very fine specimens. 



(January 9, 1893.) I have not seen the Hudsonian Chicadees 

 again. The snow is over two feet in depth, and very dry and 

 loose, making it very difficult to go about in the woods, so I 

 have not been able to do any collecting. Pine Grosbeaks and 

 Canada Jays are still common, although they have been moving 

 southwards for some time. 



All last winter .Pine Siskins (Spinus pinus) were very 

 numerous about here, but about the middle of April (1892) they 

 all disappeared except one pair, and they commenced to build
