upon which the booby will dash down so violently as t© kill itself or else will

The Darter ( Plotus ) exists as an African species as well as an American 
one. The head and neck look 
as if they belonged to a long- 
beaked snake; and in swim¬ 
ming it does not expose its 
large body, so that the resem¬ 
blance is thus increased. Add to 
this that in diving it is quicker 
than a flash and the propriety of 
its popular name is evident. 
The Sea-Swallow, or Tern 
(.Sterna hirundo ), is a gull which 
has been named from the swal¬ 
low-like, forked-shape of its tail. 
Jet black is the color of the top 
of the head and on the back 
of the neck; the under parts 
are white, and the rest of the 
body a gray ashen color; the 
legs, feet and bill are like red 
coral though the extremities are 
perfectly black. It builds the 
rudest kind of a nest out of 
sticks, stones and grass. 
Another species of the tern is 
the Noddy {Anous stolidus). It 
flies like a night-hawk, although 
its habits are not nocturnal. It 
builds its nest sometimes on the rocks and sometimes in the trees. It is a 
slovenly housekeeper, and uses the same nest year after year, adding to the 
structure until it becomes relatively 
gigantic, but never troubling itself 
about any house-cleaning. The noddy 
is about a foot and a quarter in length, 
and its nest is robbed of the eggs for 
the supply of the table. It dresses in 
a chocolate color, but varies this by 
buff on the top of the head and the 
forehead, by brownish gray on the back 
, of the head, and by black on the bill, 
on the legs, and on the feet. 
The Scissors-bill Gull (Rhyncops 
nigra) is met with alike in America 
and in Africa, and the lower mandible 
shuts into a groove in the upper in a 
manner to justify its popular name, 
grows lighter until at the base it is the color of Guinea gold. It feeds mostly 
BOOBY.
