The useful part

Every fall, the entire North American mainland population heads south to their wintering grounds. What makes this migration unusual is that the bulk of the migratory population passes any given point along their route in a two-week period.These birds are forest buteos, who live in the boreal areas of Ontario and Quebec. They are a compact, crow-sized hawk and the smallest buteo passing over our raptor watches.

How it works

  • They are a prey generalist, eating insects, small mammals, reptiles, and birds.These raptors need to fly on thermals, which is the most energy-efficient way to migrate.
  • They typically fly after a cold front has passed through, with northwest winds pushing them along.

What to take from it

They don't fly over water because there is no lift or thermal generation.

Details worth keeping

In September, one of the most-hoped for raptors is the Broad-winged Hawk. Among the earliest raptor migrants, Broadies fly in large flocks.
