The Duck Hawk breeds here and there on a few steep 

 cliffs along the Hudson and in New England. Mount Tom 

 and one or two other cliffs in Massachusetts, Eagle Cliff and 

 Dixville Notch, N. H., and Lakes Willoughby and Mem- 

 phremagog, Vt., each has an eyrie of these noble hawks.

 or a still rarer winter resident. In April and May, and 

 again in September and October, it is not infrequently seen 

 along the sea-shore, where it preys on the sea-fowl and 

 shore birds. When one approaches the cliff where a pair

 readily be known by its size, by the cut of its wings and 

 tail, and by the black "mustaches"
