 and which he performed with commendable vim. 



Within the coverts of dense woods, the male 

 invariably seeks the tallest tree-tops, seldom 

 changing his position unless to seize a passing 

 insect, or to obey the call of a kindred species. At

 the trees are covered with leaves, he is seldom

 birds, which his stationary position materially 

 assists in bringing about. In orchards and gardens 

 adjoining occupied dwellings, it is true that his 

 behavior is marked with less shyness and greater 

 freedom. The less danger which such places
