335. Sterna fluviatilis, Nauuiann. The Common Tern. 



Favier includes this species in his notes, and states that they 

 are found near Tangier in large flights on the coast during 

 migration, passing south during September and October. Pos- 

 sibly he may mean the previous species. 



The Common Tern is frequently seen in autumn and spring in 

 the Straits, and may very possibly be found nesting near Cadiz. 



Crown black, below white.

Spanish. Catalinita (Arevalo). 



"This small Tern is seen near Tangier, passing in small 

 flights along the coast and on the rivers and lakes. They arrive 

 during May, and return in September, some, however, remaining 

 in the country to breed. They all retire south for the winter." 

 Favier. 



The Little Tern occurs on the Spanish as on the Moorish side 

 and, keeping to the sea-coast, is the latest to arrive of all the 

 family. They are nowhere very abundant ; but a few nest near 

 the mouth of the Guadiaro about the end of May, as well as in 

 other localities on the coast. 



The earliest date on which noticed was on the 10th of May ; 

 and the latest was on the 25th of October. 



Primaries white, with black tips, edged on the inner web with black and 

 usually on the outer web. Length 15-16 inches.
