The black cap, pointed bill and long forked tail distinguish 

 terns from gulls. The male is very attentive and often stands 

 by his mate while she is incubating. These birds belonged to a 

 good sized colony nesting on the beach. Within a few feet there 

 were several other nests. Note the sharp-pointed bill for spear- 

 ing small fish.

 Georgian bay, Canada. (July 6, 1912) Bailey 



Eggs are laid in a mere depression in the sand or in rubbish 

 or seaweeds. Though just hatched the young birds make a pre- 

 tense of defense.
