SONG BIRDS OF OBC'HAIW AND WOODLAND. 211 



The food of these birds has l)een much discussed, and it 

 has been clearly shown that they eat a larijer })roportion of 

 fruit and a smaller proportion of insects than most birds. 

 Here in Massachusetts they often merit the name of Cherry 

 Birds, for they descend on the cherry trees in considerable 

 flocks, and destroy a large quantity of fruit. Professor Beal, 

 however, in examining one hundred and fifty-two stomachs, 

 found that only nine l)irds had eaten cultivated cherries, and 

 that more than hah" the food consisted of wild fruit. 



]\Irs. Mar}' Treat writes of a town in which the elms liad 

 been defoliated for several years by the elm-leaf beetle, ])ut 

 the Cedar Birds came, and 

 the trees were afterwards 

 comparatively free from the 

 beetles. Durino- the time 

 when the adult birds feed on 

 cherries, the young are fed 

 very largely upon insects, 

 although fruit is given them 

 as they grow older. These 

 birds feed so much on wild 

 fruit as it ripens, that it con- 

 stitutes nearly seventy-five 

 per cent, of their food ; but 

 later, after the young are reared, they turn flycatchers, and 

 taking a high perch on some tree near a lake or river or 

 on the borders of the Avoods, they sally out after flying- 

 insects. Grasshoppers, beetles, crickets, ichneumon flies, 

 crane flies, and lacewings are all devoured bv them. Bugs 

 and bark lice are also on the bill of fare. While these birds 

 are sometimes a pest to the fruit grower, they are, on the 

 whole, beneficial to agriculture, and deserve protection.

TANAGERS. 



This group of brilliant woodland birds is represented here 

 by but two species ; one of these, the Summer Tanager, is 

 very rarely seen ; the common Scarlet Tanager is one of 

 the most valuable birds of orchard and woodland.
