BIRDS OF THE CAMBRIDGE REGION.

mentioned, it was overlooked by several keen and diligent collectors, among 

 whom may be mentioned Mr. H. W. Henshaw and Mr. Ruthven Deane. It 

 has since increased in numbers and extended its range until at the present time 

 it is rather generally and commonly distributed in summer throughout most of 

 the country lying to the northward of the Lyman estate in Waltham and to the 

 westward of the town centers of Waverley, Belmont and Arlington. It fre- 

 quents deciduous woods and thickets, preferring to all other places springy runs 

 shaded by gray birches, old pastures growing up to birches and wild apple trees, 

 and dry hillsides covered with a young sprout growth of oak, hickory or maple. 

 As a rule it shuns evergreen trees, but at its seasons of migration I have occa- 

 sionally seen it feeding, with Warblers of other species, in the tops of large 

 white pines. In 1883 a male was shot by Mr. H. M. Spelman on May 14, and 

 a female by Mr. Charles R. Lamb on May 18, among the large hemlocks in 

 the grove at Fresh Pond. I, also, have found the species within the limits of 

 the city of Cambridge on one occasion — August 21, 1875, when I killed a young 

 female in full autumn plumage in the Maple Swamp. Miss Bertha T. Parker 

 tells me that she saw an adult female near the Museum of Comparative Zoology 

 (in Palfrey's Woods) on May 9, 1900.

Nuttall, apparently, did not meet with the Nashville Warbler living, although 

 he states ^ that it " occasionally proceeds as far north as ... . the neighborhood of 

 Salem in this state." In common with Audubon and Wilson he regarded it as
