ported the Hudsonian Curlew to be a "very rare migrant," and 

 appearing with the Long-billed Curlew.* Mr. Robert Ridgwax' 

 reports this species as much rarer in Illinois than the long-billed 

 species, and says, it "never remains within the State during the 

 breeding season."f 



Its range includes the whole of both North and South 

 America and the West Indies. It breeds very far north and 

 winters chiefly south of the United States.

As shown by records, this species was formerly a common 

 migrant, but at the present time it is certainly a very rare migrant. 

 Mr. Robert Kennicott, in his "Catalogue of Animals observed in 

 Cook County, Illinois," || reports the Eskimo Curlew simply with 

 the notation "common." This note, however, becomes of little 

 value, for Mr. Kennicott lists the bird under the common name 

 "Esquimaux Curlew" and gives the scientific name "Numenius 

 Hudsonicus." I am not aware that hudsonicus has ever been 

 called Eskimo (or Esquimaux) Curlew, though the two species 

 have been somewhat mixed by earlier writers. 



Its range extends over the whole of eastern North America, 

 breeding in the Arctic regions and in its migrations reaching 

 the southern extremity of South America.

This fine bird is now a quite rare migrant. I have always 

 found it in company with other maritime species. I have 

 taken an adult specimen in full breeding plumage in August,
