Red-tailed Tropicbird Phaethon rubricauda 



Munro (1942) reported that he had seen "tropicbirds" flying over

 ture records pertaining to the occurrence of this species on Pearl and 

 Hermes Reef. Red-tailed tropicbirds have been reported previously 

 from all the rest of the Hawaiian Leeward Islands (Bryan and Green- 

 way, 1944; Richardson, 1957; Kenyon and Rice, 1958). A summary
