brooks: FALKLAND ISLAND BIRDS. 147 



They breed in the western part of the Falkland group where T was 

 iniable to go, and are to be seen in small numbers flying oft' any shore. 



During the latter part of February they were seen between the 

 Falklands and the Strait of Magellan, and through the entire straits 

 but not entering the Pacific where only D. cxsidana was observed.

 The fleshy eye-ring is bright red in life.

 their backs, and are unable to rise. They also feed on penguin eggs. 



They are very pugnacious about a carcass, the adults fighting

 daring only to fight other young birds. The young in fighting make
