ORDERS OF BIRDS— FLIGHTLESS DIVERS 
the fact. Of all birds that love water, I think 
the Penguin loves it most. It will lie on its 
side at the surface, and in sheer playfulness 
and excess of joy, beat the water with its upper- 
most wing, wriggle about, then turn over and 
splash with the other. 
In the sea, a flock of Penguins is readily 
mistaken for a school of dolphins, because they 
dive so persistently, in order to swim with their 
wings, and thus get on in the world very much 
faster than if they sat up and paddled with 
their feet. 
There are about twenty species of Penguins, 
of which the Emperor is the largest, and the 
King Penguin second. All are found in the 
southern hemisphere. The largest Emperor 
Penguin ever weighed and recorded, weighed 
78 pounds! Needless to say, these birds live 
almost wholly upon fish, in the capture of which 
they are the most expert of all birds.
