Vegetable food. — The vegetable food consists entirely of a few 

 berries and seeds. No trace of any product of cultivation was found, 

 except possibly 2 seeds of raspberry or blackberry found in 1 stomach, 

 but those wore probably wild. The only possible criticism that can 

 be made is that the bird may distribute a few poison-ivy seeds, for 

 1 seed of this noxious plant was found in 1 of the stomachs. 



The following fruits and seeds were identified: 



Elderberry (Sambucus canadensis). . . 2 



Blueberry ( Yaccinium sp.) 1 



Alternate-leaved dogwood" (Cormis 



alternifolia) 1 



Rough-leaved dogwood (Cornus as- 



perifolia) 1 



Poison ivy (Rhus toxicodendron) 1 



Blackberry or raspberry (Rubus&p.). 1 



Poke berry (Phytolacca dccandra) .... 2 



Panic grass seed (Panicum sp.) 2 



Food of nestlings. — Among the stomachs were those of 2 broods of 

 nestlings, and these were separately considered to discover possible 

 differences in diet. One brood of 2 was labeled "just hatched," and 

 the food was found to consist of grasshoppers, 52.50 per cent; bugs 

 (Hemiptera), 32.50; and spiders, 15 per cent. The other brood of 4 

 was simply designated as "nestlings," with no hint as to their age. 

 Their food consisted of grasshoppers and crickets, 66.25 per cent; 

 flies (Diptera), 12.50 per cent; caterpillars, 17.50; and spiders, 3.75 

 per cent. This food does not differ essentially from that of the adults, 

 except that the softer elements have been selected. The grasshop- 

 pers were, many of them, immature, and they entirely filled one 

 stomach.
