- The Hudsonian Chickadee is resident in I^abrador and the Hud- 

 son Bay region. It is given as a resident of Northern New England,: and 

 breeds on the Island of Grand Manan, New Brunswick. Audubon found' 

 a nest of this Chickadee in L,abrador, built in a decayed stump about 

 three feet from the ground and composed entirely of the finest* fur of 

 various quadrupeds, chiefly of the northern hair, and all so thickly and 

 ingeniously matted throughout as to seem as if felted by the hand of 

 man. Mr. Montague Chamberlain mentions several nests that were 

 found in New Brunswick, one of which was built in a cavity of a tele- 

 graph pole and others built in decayed stumps. He says that when 

 this species is excavating for its nest it sometimes enters from the side 

 of a tree and not invariably from the top of a stump. Mr. James W. 

 Banks, during the seasons of 1885 and 1886, discovered three nests, the 

 entrances of which were at the side of a decayed stump. One of these- 

 nests is about two inches deep and is set on a cushion of dried moss, 

 and besides the felted fur there is considerable dry moss mixed, 

 throughout. The entrance was about six inches from the top of the 

 nestt 



The eggs are usually six or seven in number. A set of seven in Mr. 

 Norris' cabinet was taken June 9, 1876, at Grand Manan, New Bruns-, 

 wick, from a cavity in a dead tree about five feet from the ground,; 

 They are- creamy-white sprinkled with hazel. Sizes .55 x .48, .58 x .46, 

 .60X.46 , .56X-.47, .56X.47, .56X.47, .55X.48. The eggs of the
