STRIGID^.— SUKNIA ULULA. 81 



in regard to their eggs, is derived from Richardson's Northern Zoology. We are 

 there informed that it builds on a tree. Its nest consists of sticks, grass, and 

 feathers. It lays two white eggs. It is exclusively an Arctic species, and is com- 

 mon to the northern regions of both continents. Occasional specimens are obtained 

 in different parts of the United States, though none, so far as I am aware, farther 

 south than New Jersey. It is, however, a rare species,' excepting in the Arctic 

 regions, where it is said to be quite abundant. Only a single specimen is kno'vvn 

 to have been taken in Great Britain, and it has only occasionally been met with in 

 Germany. From this we may infer that it is as rare a bird in the more temperate 

 parts of Europe as in the corresponding regions of America. 



' Mr. Audubon, in his account of the Hawk Owl, states that he had received a letter from me inform- 

 ing him that the Hawk Owl is very common about Memphremagog Lake in Vermont, &c. This was 

 a mistake, and an unintentional misquotation of what I wrote. I did not make this statement as of my 

 own knowledge, for I had never been in that region, but as the information given me by a resident of 

 that part of the country, which I have since had reason to believe is incorrect. The Hawk Owl is 

 probably a rare species throughout Vermont.
