260 BIRDS OF ONTARIO. 



distributed, each pair taking possession of a certain "limit," which 

 is valiantly defended against all intruders, no bird, however large,, 

 being permitted to come with impunity near where the Kingbird's 

 treasures are deposited. It is partial to pasture fields, a favorite 

 perch being the top of a dry mullein stalk. Here the male sits like 

 a sentinel, issuing his sharp note of warning, and occasionally darting 

 off to secure a passing insect. When the breeding is over and the 

 young are able to shift for themselves, he gets over his local attach- 

 ments and quietly takes his insect fare wherever he can find it r 

 allowing other birds to do the same. 



The food of this species consists almost entirely of insects, which 

 it takes while on the wing. It may be considered a friend of the 

 farmer, for although it does take a few bees now and then, it more 

 than compensates for these by the large number of injurious insects 

 which it destroys. 



The contents of the twelve stomachs examined by Dr. King, of 

 Wisconsin, were as follows : Four haql eaten seventeen beetles ;. 

 four, four dragon flies ; one, a bee ; one, six crane flies ; one, a large 

 moth ; one, a butterfly ; and three, a few raspberries. 



It is common throughout Manitoba and the North-West, retiring 

 south when its supply of food is cut off by the advance of the season.
