that each hawk captured 200 grasshoppers a day, and that tb.ere 

 were 200 h'awks, 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 specie.?, 

 for whose destruction a bounty has recently been offered !

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-winiged Hawk has been 

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