Likewise, the field-lark spends the summer in the North, and in the fall and winter he makes his home in the South. (Fig. 118.) 253a. Make a list of the kinds of birds, found in the county. How many kinds are permanent residents, and how many visit for only a part of the year? 254. The Feeding Habits of Birds. The farmer is interested in the birds because they eat the insects that destroy his crops. The illustrations. Figs. 119 and 120, show how much of each kind of food some common birds eat. Some birds, like the swallows and scissor- tailed flycatcher, live on insects almost entirely. Others, like the dove, eat nearly all weed seeds and gram, but most birds eat some of both. It will be interesting to Fig. 118. Meadow lark or field lark.
