Fall migration. — In common with other hawks of this and other 

 genera, the broadwing sometimes travels southward in large loose 

 flocks. Observations of these flights have been made from several 

 points, notably in the vicinity of New York City and in New Jersey. 

 They generally occur in September, when as many as 1,000 birds 

 have been estimated in one flock.

 4; and Athabaska Landing, September 5. Manitoba — Shoal Lake,
