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.
