OENITHOLOGY. 



This handsome species is apparently a more northern bird than the 

 succeeding, but the two have been constantly confounded with each 

 other, and with Ihis falcinellus of the Old World, so much so, in fact, 

 that it is almost impossible to separate their synonymy. 



This bird is larger than the South American species alluded to in 

 the article immediately succeeding, and which appears to be a summer 

 visitor to the southwestern countries of the United States. The pre- 

 sent species we have never seen from South America. 



Specimens in the collection of the Expedition are labelled as having 

 been obtained in Oregon, into which country this species appears to 

 extend its migration in summer, probably inhabiting the entire western 

 coast of North America. This and allied species are regarded as form- 

 ing the genus Falcinellus, Bechstein, adopted by the Prince Bonaparte 

 in his Monograph of the family Tanialidce, in Conspectus Avium, II, 

 p. 149. 



Dr. Pickering mentions this bird as occurring at Vancouver, Oregon.

This species inhabits apparently nearly the entire southwestern 

 regions of the continent of America, from New Mexico and California, 

 to Patagonia. It is of frequent occurrence in Peru and Chili, and,
