ECONOMIC RELATIONS OF OUR BIRDS. 
quarrelsome disposition of this species. According to his observations, Hawks, 
Owls, Crows, Crackles, Jays and Cuckoos are about the only birds which it reg¬ 
ularly attacks. For these it is always on the alert, and with good reason, no 
doubt. He also states that a pair of these birds once had their nest in an apple 
tree in which the Baltimore Oriole and the Robin had their nests at the same 
time, and that the three families appeared to entertain the most amicable rela¬ 
tions. My own observations are in harmony with these statements. A pair of 
Warbling Vireos once had their nest in an oak tree in a pasture which also bore 
a nest of the Kingbird. The two nests were only four feet apart, and both con¬ 
tained half grown young when the discovery was made. 
The only apparently serious objection to this species with which I am ac¬ 
quainted is its destruction of dragon-flies, and of these insects it appears to be 
veiy fond. How serious this objection may be, future investigation must decide. 
Food: Of twelve specimens examined, four had eaten seventeen beetles; four, 
four dragon-flies; one, a bee; one, six crane-flies; one, a large moth; one, a but¬ 
terfly (Pieris protodice); and three, a few raspberries. 
Bees, the large black gad-fly and other insects (Wilson). Insects, among them 
bees, and some berries (Cooper). Mostly winged insects, occasionally grasshop¬ 
pers and bees (Samuels). Dragon-flies are a favorite food; it also eats bees and 
may-beetles (J. L. Hersey, Am. Nat., Ill, 437). Of seven stomachs examined, 
two contained hymenoptera; one, a wasp; flve, lepidoptera; two, caterpillars; 
four, beetles; one, ground-beetles; three, orthoptera; one, crickets; one, locusts; 
two, grasshoppers; one, a spider; one, a harvest-man; ‘one, wheat; and one, 
fruit (Forbes). Of the food of two specimens shot in an apple orchard, canker- 
worms, which infested it, made forty-three per cent., vine-chafers f Anomala 
hinotataj seventeen per cent., spring-beetles (MelanotusJ ten per cent., scaven¬ 
gers twenty [per cent., Lampyridae three per cent., and various hymenoptera 
seven per cent. (Forbes).

Group I. Class b. 
This species is certainly rare in Central Wisconsin, but is given as a rather 
common summer resident in Northeastern Illinois, and Dr. Hoy gives it as 
breeding at Racine. It is said to inhabit damp swampy woods, and to be quar¬ 
relsome toward birds smaller than itself. 
Food: Bees, and other winged insects until fall, when it eats berries (Wilson). 
Insects, grapes and berries (De Kay). Winged insects, berries, caterpillars, 
crickets and grasshoppers (Samuels). Insects as long as they can be obtained, 
then grapes and several species of berries.

Probably accidental in Wisconsin. Dr. Brewer states that one specimen was 
obtained by Dr. Hoy near Racine, and sent to Mr. Cassin for identification.

Class b. 
This familiar and confiding species arrives early in April and remains until the 
beginning of October. During this long stay it leads a busy, useful life, though 
not one wholly unalloyed with mischief. It is an expert fly-catcher, but, like
