ECONOMIC RELATIONS OF OUR BIRDS 
few berries which it occasionally eats are valueless compared with the service 
wliich it is capable of rendering. 
Food: Of twenty-nine specimens examined, one had eaten ants; three, three 
ichneumon-flies, two of them Thalessa hmatorf, the other a small species having 
an extent of wing of one-tenth of an inch; eight, twenty-six caterpillars; 
three, six diptera, three of them tipulids; seventeen, forty-seven beetles; three, 
six hemipterous insects; four, seven grasshoppers; one, a small dragon-fly; one, 
a very large spider; and two, ten harvest-men. Curculios, elaters and leaf-chaf¬ 
ers, some of them three-fourths of an inch long, were repi’esented among the 
beetles. From the stomachs of three young birds less than a week old were 
taken four caterpillars, one fly, one small grasshopper, one hemipterous insect, 
together with undetermined fragments. 
Wasps, hornets, humble bees and other large winged insects; also, cherries, 
huckleberries and other fruits (Wils.). Insects found among tall cottonwood 
trees, and frequently a kind of bee found on laurea bushes (Cooper). Insects 
and their larvae, preferring beetles, wasps, etc.; also, berries and gi’apes (De Kay).

Mr. Thure Kumlien informs me that he obtained a pair of these birds breed¬ 
ing near Busseyville, in May, 1877. The bird appears, however, to be out of 
place, 
Food: Insects and berries (Cooper). The stomach of a specimen examined by 
Dr. Suckley contained insects, principally coleoptera, among them many frag¬ 
ments of a large BujJrestis, found generally on the Douglas fir-trees (Coues).
