157. [641] Hcliiiiitthoiilttla pinus (Linn.). Blue- winged Warbler.* 



Abundant migrant. Rare summer resident (C. H. B. B. W. E.). 

 April 19 to September 28. Song April 19, 1903. 



Orchards and open woods are the favorite haunts of the Blue-winged 

 Yellow Warbler. 



On a bright day after a rainy morning in April, 1903, warblers of this 

 species were observed to move from one part of the country to another 

 about three miles away in from six to eight hours. In the morning 

 they were plentiful in the orchard and clearings south of the city, while 

 none were to be observed anywhere north of town. In the afternoon 

 these conditions were reversed, they were common and singing in the 

 orchards north of town, while they were entirely absent in the places 

 where they had been seen in the morning. Their movements even for 

 the shortest distances were always in the same direction, they flew from 

 limb to limb, from tree to tree, in the same general trend, toward the 

 north.
