poses, it is the same song. I am inclined to describe it as slower and 

 more pronounced, but after all the difference is minor. 



Arthur H. Howell (1932) describes the song of virens as *'a drowsy, 

 drawled ditty of four or five notes, wee-wee-wee-su-see, the next to 

 last note on a lower pitch and the final one distinctly higher." This 

 portrays quite well the song of waynei, except for the number of 

 notes, which are much oftener seven than less, the first five being 

 exactly alike, the sixth descending, and the seventh ascending. 



Frank M. Chapman (1907), quoting Gerald Thayer, says oivirens 

 that "most of the individuals in a region sing nearly alike ... but 

 about one in forty does queer tricks with its voice. Among the com- 

 monest of these tricks is the introduction into all parts of the sono- 



of a pronounced quaver or tremulo The song is sometimes dis''- 



guised almost past recognition." He states further that the "delib- 

 erate song of five (sometimes six or eight) notes, is the one usually 

 described in books." 



I have never noted any "quaver or tremulo" in the song. It may 

 occur, but in the scores of times I have heard the song it has not taken 

 place. Nor can I recall any song of eight notes. Occasionally, ^ayna 

 will utter only five notes, but this is the marked exception and not the 

 rule. Certainly, individuals in a given region sing exactly alike, and 

 indeed, all the specimens I ever heard sounded alike, except for the 

 occasional slight variation in number of notes. 



FaU.—T\\Q length of stay of waynei in its summer range has not yet 

 been determined with certainty. Few departure dates have been re- 

 corded, but in all probability the bird is a rather early migrant. 

 Occurrence of the song decreases markedly after the nesting season^ 

 making the birds' movements much more difficult to trace. It will be 

 recalled that young were noted flying on May twenty-fourth, in the 

 Dismal Swamp of Virginia. South Carolina birds were seen to fly 

 "a few feet" on April twenty-eighth, almost a month earlier. The 

 North Carolina records show that yotmg were noted "in June" prob- 

 ably early in the month. That multiple broods are raised is also some- 

 thing of an open question, though it seems that in South Carolina two 

 are raised. Henry H. Kopman (1904) states that on July 30, 1897, 

 he took one at Beauvoir, Miss., on the Gulf coast, and later comments 

 (1905) that "Professor Cooke [W. W.] is inclined to think" that the 

 Beauvoir bird was a stray. Probably it was a stray, and in view of 

 what we know today, the chances are that the bird was a specimen of 

 waynei. Many of the birds of course linger much later than that ; on 

 September 29, 1935, Earle R. Greene [MS.] noted one at Lake Mat- 

 tamuskeet, N. C. This is doubtless a rather late date and may be 

 taken as about the limit of its stay along the Atlantic coast.
