AGRICULTURAL EXPERIMENT STATION, 65 
mon in the river bottoms. It is generally known as the Bee 
Martin. Stomachs of the specimens secured contained traces 
of beetles, grasshoppers, black ants, red raspberries, black- 
berries, and wild cherries. 
88. GREAT CRESTED FLYCATCHER. 
Myiarehus crinitus (Linn.). 
Summer resident; common along the rivers where heavy 
timber abounds, This species differs from the rest of the fam- 
iliy of Flycatchers, inasmuch as it builds its nests in holes in 
trees and stubs. Occasionally it nests close to farm buildings. 
In never excavates holes for itself, but finds a natural hollow 
or a deserted Woodpecker’s hole. In eastern Pennsylvania its 
food consists largely of the following insects: Amzsopterix 
pometaria and A, vernata, Pieris oleracea (Oleracea Butterfly ), 
P. rape (the imported cabbage butterfly), Coléas philodice 
(sulphur butterfly), corn worm (Gortyna zee), house fly 
(JZusca domestica), white-lined house fly ( Zabanus lineola), 
stabie fly (Stomoxys calcitrans), red ant Lormica sanguinea), 
field cricket ( Gryllus abbreviatus), mosquito ( Culex teniorhyn- 
chus), and red-legged locust ( Caloptenus femur-rubrum), be- 
sides large numbers of beetles. They occasionally feed upon 
the fruit of wild strawberry (//ragaria virginiana) and wild 
red raspberry (Rubus strigosus). 
89. PEACE BE, 
Sayornis phcebe (Lath.). 
; 
Summer resident; common. This agreeable bird was met 
with everywhere. Its food, like that of all Flycatchers, con- 
sists mainly of insects. In addition to the insects mentioned 
under the last species the following have been found in stom- 
achs of those killed in eastern Pennsylvania: Crane fly ( 77pzla 
ferruguinea), banded horse fly ( Tabanus cinctus) Turnus but- 
terfly (Papilio turnus), ground beetle) Lachnosterna quercina). 
I have also found them feeding occasionally on the fruit of red 
cedar ( Funiperus virginiana) and red currant (A7bes rubrum).
