WARBLERS 553 



Davie describes a set taken at Listowel, Ontario, June 7, 

 1895. The nest was placed in a cluster of raspberry vines in 

 hardwood timber. The nest is composed of shreds of leaves, 

 fibers of bark, grass, rootlets and hair. The eggs measure 

 0.79 X 0.56, 0.81 x 0.57, 0.81 x 0.56, 0.80 x 0.57. These eggs 

 are described as being similar to Mr. Thompson's set save that 

 in two of the eggs the markings are sparingly distributed over 

 the surface as well as at the larger end and in one specimen 

 the markings are fine and pretty evenly distributed through- 

 out. (Davie, N. & E. N. A. B., Ed. 5, p. 450). 



Mr. Thompson describes the song as " beecher-beecher- 

 beecher-beecher-beecher-beecher " or another type as " fru- 

 chapple fru-chapple fru-chapple whoit." (P. U. S. N. M. 13, 

 p. 621-622). In Warbler Songs, p. 49, the following are 

 ascribed to this species : — "wheat-a; wheat-a; wheat;" "wheat, 

 our winter wheat;" " chip-che-a-wee; chip-che-a-wee; chip- 

 chee-a-wee; " "wheat, winter wheat, winter wheat, winter wheat; " 

 "wheat here; " "wheat; " "wheat-it-ta, wheat-it-ta, wheat." In 

 habits the species is said to be largely terrestrial, seeking much 

 of the food on the ground, and seldom save in migration being 

 found in the trees. The call is a "chip" or a "chuck."
