ROSEATE TERN. 
STERNA DOUGALLI. 
The Roseate Tern is a periodical visitant in Great Britain, 
and has been named Sterna Dougalli in compliment to Dr. 
McDongall, who first noticed the bird on the Cnmbray 
Islands in the Frith of Clyde ; since which it has been found 
to breed annually on several parts of our coast. 
The geographical distribution of the Roseate Tern extends 
over many parts of the European continent, but nowliere 
in greater numbers than on the Fern Isles, the Scottish 
coast, and the coast of Northumberland; on the Dutch 
coast it is sometimes met with in the months of August and 
September. 
The localities frequented by the present species, are the 
rocky shelves of the spots before enumerated, where the com¬ 
mon tern abounds, and the eggs procured have been found 
among those of that species ; and it seems probable that the 
birds in question breed in companies, as those found were 
in groups of ten to twenty. More than the partial and im¬ 
perfect information on the subject of the Roseate Tern here
