This little Falcon, like the Peregrine, is resident, locally, through- 

 out the State, but is comparatively rare. Like its larger relative, 

 if nests in cavities of large trees in the forest, Imt wliere suitahle

 flight and its courage and enterprise in attacking birds as large or 

 even larger than itself, though generally it only preys upon smaller 

 birds, such as Grakles, Ked-winged Blackbirds, liobins, and Pigeons."
