64 BIRDS OF THE PUBLIC GARDEN 



short distance to another perch. The same 

 thing was repeated, and still the bird did 

 not fly from the Garden. The characteristic 

 traits of this species of hawk were well 

 brought out, therefore, by its manifestation 

 of sluggishness and an absence of suspicious 

 fear, also by its short flights. It prolonged

n. AMERICAN SPARROW HAWK 



Falco sparverius 



On one occasion only, in the early morn- 

 ing of May 9, 1908, has a Sparrow Hawk 

 been seen within the Garden. It was found 

 perching high in the tall gingko tree which 

 stands near the Ether Monument, and it 

 did not take wing for perhaps ten minutes, 

 when it flew off over the line of Common- 

 wealth Avenue in the direction of the Fens, 

 where it has been found to be a usual bird 

 during the winter season.
