This exquisitely beautiful and graceful bird is quite abundant on the prairies of southern 
Texas, and is everywhere conspicuous among its kindred species. It is usually known as the 
scissor-tail from the habit of closing and opening the long feathers of the tail like the blades 
of a pair of scissors. The adult female is very similar, though rather smaller. The young 
is not conspicuously different, only lacking the concealed patch of the head.
