BROAD-WINGED HAWK. 205 



that each hawk captured 200 grasshoppersTa day, and that there 

 were 200 hawks, the daily catch would thus be 40,000 grasshoppers. 

 At this rate these hawks would destroy 280,000 grasshoppers in a 

 week, or 1,200,000 in a month." And yet this is one of the species 

 for whose destruction a bounty has recently been offered 1

This species was first described by Wilson, who met with two 

 individuals in the woods near the Schuykill, but does not appear to 

 have seen it again. 



In Southern Ontario the Broad-winged Hawk is often very com- 

 mon in the spring. Toward the end of April, or early in May, should 

 the weather be clear, great numbers are seen soaring at a consider- 

 able height, and moving in circles toward the North-West. 



About the same time, singly or in pairs, it may be met with in 

 the woods, usually sitting quietly on the lower branch of a tree near 

 some wet place watching for frogs. A few pairs remain during 

 summer, but the greater number pass on to the North- West, and in 

 winter none have been observed. 



Late in April, or early in May, the Broad-winged Hawk has been 

 reported at Ottawa, Toronto, Hamilton and London. It does not go
