1 16 FALCONID^ : HAWKS. 



apparently prevented their breeding there that year, as 

 they probably otherwise would have done ; at least no 

 nest was that year discovered. In 1868 Hawks of this 

 species were seen about the mountains, and, although 

 they reared their young there, all effort to discover their 

 nest was ineffectual. The present year (1869) they 

 commenced to lay in the old nesting-place, but as they 

 were robbed when but one egg had been deposited, they 

 deserted it, and chose a site still more inaccessible. 

 Here they were equally unfortunate ; for, during a visit 

 to the mountain in company with Mr. Bennett, April 28, 

 we had the pleasure of discovering their second eyrie, 

 and from which, with considerable difficulty, three freshly- 

 laid eggs were obtained. Not discouraged by this 

 second misfortune, they nested again, this time de- 

 positing their eggs in the old eyrie, from which all, 

 excepting the last set of eggs, have been obtained. 

 Again they were unfortunate, Mr. Bennett remov- 

 ing their second set of eggs, three in number. May 23, 

 at which time incubation had just commenced. The 

 birds remained about the mountain all the summer, 

 and, from the anxiety they manifested in August, it 

 appears not improbable that they laid a third time, and 

 at this late period had unfledged young.

 American Naturalist, v, 1871, p. 82. Our latest accounts 

 of the nidification are given by Mr. F. H. Knowlton in 

 the Nuttall Bulletin, v, 1880, p. 57, from observations 

 made at Brandon, Vermont, where a pair of Duck Hawks 

 are known to have bred for more than twenty years. 



As to the distribution of the Duck Hawk in New 

 England there is little to note, the bird being of general 

 though infrequent or irregular occurrence, excepting in
