110 LAND-BIRDS AND GAME-BIRDS 



borders of the Great Lakes, through Ohio, southern Illinois 

 (Ridgway), down the Mississippi Valle}', across into Texas 

 and so on into Mexico and Central America where the}' winter. 

 Returning in spring they (at least D. castanea) pursue a more 

 southern route, keeping along the coast as far as the New 

 England States, where they ascend the Connecticut Valley, 

 generally avoiding eastern Massachusetts." 



(d). " The first part of the song is like that of the Black- 

 poll Warbler, but it has a terminal warble similar to that of 

 the Redstart to which it bears a striking resemblance, with the 

 exception that it is given with less energy." The Bay-breasted 

 Warblers are usually' silent during their migrations.

 ous (-ash? ) and black. Croion clown to the eyes black. Sides of 

 the head and under parts, white. Sides of the breast marked 

 "with black streaks which crowd into a fine chain running to the 

 bill. Wing-bars and tail-blotches, white. 9 . Dusky olive- 

 green above, black-streaked. Under parts not (usually) pure

 Green," though coarser. It is usually placed near the ground, 

 in an evergreen, and always in the thick woods. It has never 

 been found in Massachusetts, but in northern New England it 

 is generally finished in the latter part of June. The eggs of 

 each set, usually four, average about •GSX'iiO of an inch, and 

 are commonly (grayish-?) white with spots and blotches of 

 purplish and different browns. The blotches predominate, and 

 are scattered over the whole egg. Other forms occur.
