There are a number of birds which are valuable 
friends to all the people because they are scavengers. 
The Herring Gull, which is the commonest gull of the 
harbors of the United States, and which is also found 
on inland lakes and rivers, by feeding upon all kinds 
of refuse animal and plant materials makes the waters 
about our cities more healthful. This is especially true 
of the coast cities which dump their garbage into the 
waters not far distant. The Turkey Vulture, the Black 
Vulture or Carrion-Crow, and the California Condor 
make the fields and woods of the country more health- 
ful by devouring the carcasses of animals, and the first 
two species eat the offal from slaughter houses and even 
scraps of meat from the markets in some of our South- 
ern cities. 
The most valuable group of birds from the stand- 
point of the farmers, the orchardists, and the gardeners
