A Plea for the Birds 337 



Two species of bluebirds inhabit the Western States, 

 the mountain bluebird and the Western bluebird. 



The birds of beautiful plumage are the insect eaters. 

 Nature intended the birds to do their work by 

 ridding the earth of insects. It is claimed that 

 insects carry germs that cause two thirds of the 

 world's diseases. The greater the number of 

 insects, the greater the loss of life. Saving a bird 

 means saving human life. A wren will eat from 

 twenty-five to fifty worms in fifteen minutes.
