BIRDS OF BERMUDA. 189 



From April 30 to May 11, 1875, there were not a few visitors, and sev- 

 eral specimens were obtained. Five of these birds frequented the grassy 

 slopes in the vicinity of Warwick Camp, while I was going through the 

 annual course of musketry there with my company. They disappeared 

 on May 11, without my having been able to procure a specimen.
