ern New Jersey, northern Illinois and northern Nebraska northward 

 to Newfoundland and the Great Slave I^ake region ; the breeding 

 range seems to be limited to the AUeghanian and Canadian faunce.

 and occasionally north to the Rio Grande River and Texas. 



The Nashville Warblers do not hurry into Maine afthe ap- 

 proach of spring weather, but rather prefer to await the time when 

 warm weather is more surely established. They appear in southern 

 Maine about May yth, and in the region about Bangor the average 

 date of arrival is about May 15th, varying somewhat from as early as 

 the loth to as late even as the 20th. 



During migration they may be found in scattered bands (asso- 

 ciated with other Warblers and very often accompanied by one or 

 two Tennessee Warblers), frequenting the edges of woods and 

 thickets and almost always to be found at this season in alder thickets 

 and bushes bordering roads, brooks, rivers, ponds or lakes. A 

 smaller proportion of individuals may be found scattered by ones 

 and twos through open hard-wood growth and in the taller trees. 



They are quiet, unpretentious little bus}bodies, silently passing 

 from twig to twig in search of food. They do not seem to make any 

 particular demonstrations of love or affection for their companions, 

 nor have I ever observed the ceremony of selecting their mates, such 

 as so commonly occurs with some others of our Warblers. 



During the nesting season they frequent rather open hard-wood 

 growth, most often placing their nest on some mossy hummock near 

 the edge of the woods. They will by choice seek birch growth in 

 the vicinity of Bangor, nesting either near the edge of the woods or 

 in a bushy pasture or thicket. In northern Maine I have found 

 them nesting on hillsides among rather open spruce growth, placing 

 the nest in moss on the ground. 



Nest building begins soon after the birds are established in their 

 summer homes. Presumably the female does most of the work, as 

 while watching an individual nest building I heard its mate in a 

 near-by sapling repeatedly singing "pea-cie-pea-cie'hit-I-hit-I-hit."
