Birds are excellent source of food. Chickens and turkeys
are examples of birds which supply man with great quantities
of meat. Chickens and other birds also supply eggs. Farmers
consider most birds as friends because they destroy insect
pests and the seeds of weeds. Birds are useful to people. Salt
Lake City has a monument to sea gulls, which ate up many
thousands of crickets that threatened crops of the Mormon
farmers. Many birds of prey destroy harmful mice, rats, and
ground squirrels.
