white, thickly marked with cinnamon- and olive-brown, with frequently a 

 wreath about the larger end, '70 x "50. Date, Waynesburg, Pa., May 14; 

 New Haven, Conn., May 20; Cambridge, May 23; Lancaster, N. H., 

 June 7; Black Hawk Co., Iowa, May 19; se. Minn., May 24. 



When any one tells me he has seen a "Wild Canary," I feel reason- 

 ably sure he refers to the Yellow Warbler, for the casual observer at 

 once betrays his inexperience by entirely overlooking the bird's streaked 

 breast and slender bill. It has, it is true, the general appearance of a 

 yellow bird, and its bright colors and preference for gardens, orchards, 

 the shrubbery of our lawns or bushy brooksides, instead of the woods, 

 frequently bring it to the attention of those to whom most birds are 

 strangers. It is an active bird, and its song wee-chee, chee, chee, cher- 

 wee though simple, has a pleasing, happy ring.
