The Secretary read a letter from Mr. N. B. Moore of Min- 

 neapolis, Minn., stating that he had taken a pebble of con- 

 siderable size from the stomach of a common night-hawk, 

 shot in Iberville Parish, Louisiana. The Avriter considered 

 this to be an interesting fact, because the bird is of insectiv- 

 orous habits, and feeds while on the wing. He also i-emarked 

 upon the increasing distribution of the same bird. 



Mr. Audubon, in his " Birds of America," states that this species is 

 seen in Louisiana only during its migratory passage, chiefly in spring. 

 They now breed there, though, so far as I know, hardly so far south 

 as the parish named; yet even there I saw, last spring, some symptoms 

 indicating a disposition to breed ; and I am convinced that these birds 

 are now accustomed to breed in localities unfrequented by them for 

 that purpose, when Audubon resided in Louisiana, thirty-five or forty 

 years ago.
