The Lesser White-rumped Redpoll is a very rare winter visitant 

 to the extreme northern portion of the State. I have seen speci- 

 mens in the collection of Mr. E. W. Nelson, that were collected in 

 the vicinity of Chicago, hut I am unable to give dates of their 

 capture. The National Museum likewise possesses specimens from 

 Mount Carroll, collected hy Dr. H. Shimer. This species breeds 

 abundantly throughout the subarctic districts, from northern Labra- 

 dor to western Alaska, whence numerous specimens both of the bird 

 itself and its nest and eggs have been sent to the National Museum ; 

 but we have not, as yet, any account of its distinctive habits.
