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

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

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.
