TENNESSEE WARBLER 125 



Mass., and northern New York and New England. In the 

 vicinity of New York city, however, and throughout most 

 of southern New England, including the neighborhood of 

 Boston, it occurs chiefly as a migrant. It is often very com- 

 mon throughout May, and again in late September and early 

 October. It may then be seen wherever migrating warblers 

 are found, — in the village streets, about houses, and along 

 the edges of streams or swamps. It generally keeps well 

 up in the tops of trees, where it often clings like a Chicka- 

 dee to the ends of small twigs. 



Like many of our other warblers the Parula has two 

 songs : one is easy to learn, a series of zee-like notes, which 

 rise quickly and end in a little zip, as if one were winding 

 up a little watch ; the other, though of a less distinctive 

 form, has the same hoarse quality. 



This is our smallest warbler, and should be confused with 

 no other bird, if one can get a view of the bluish head, the 

 yellow throat, and white n-'uig-bars.

The Tennessee Warbler is a migrant through New York 

 and New Englana, in May and September ; it is usually 

 very rare, though sometimes common in the autumn in the 

 lower Hudson Valley. On migration it frequents apple or- 

 chards and tall woodland trees, but in northern New Eng- 

 land, where it breeds sparingly, it frequents larch swamps 

 and occasionally spruce growth. On account of its lack of 

 bright colors it is the least likely of the rare warblers to 

 come under the notice of any but an expert field ornitholo- 

 gist. Its song is a series of sharp slfs, like a Black-poll's,
