This retiring and peculiarly terrestial species, though a common summer resi¬ 
dent, is not as abundant as its two broods should tend to make it. Doubtless 
some fatal enemy holds it in check. Groves, thickets and woods crowded with 
underbrush, in upland situations, are its favorite haunts. From those resorts it 
only makes occasional visits into the adjoining fields or gardens, if near at 
hantl. It is a large, strong bird, and capable of doing great miscliief to the 
insects that infest its haunts. 
Food: Of seventeen specimens examined, five had eaten small seeds; one, 
wheat; one, oats; one, raspberries; one, seven moths; three, nine beetles; one, 
ants; one, a wasp; one, an ichneumon; two, three grasshojipcrs; two, two cock¬ 
roaches; one, a fSpectriim feinoratuinj, and four of its eggs; and 
one, a larve. 
Worms, beetles, and eggs of insects (Wilson). Earth-worms, wire-worms, 
and the larvm of insects (De Kay). Worms, insects and seeds (Samuels). 
Beetles and seeds of weeds (Forbes). 
Note.— The following is found as a foot-note in Birds of Northeastern Illinois: 
“ Through Dr. Ho}^ I learn that tw'o specimens of P. arcticus have been taken in Wisconsin, one 
near Milwaukee, where it is now preserved, and a second opposite Dubuque, Iowa. He has seen 
both specimens and is positive of their identity.”
