spirit and a still earlier close of even-song, except, it may be, in 

 the case of a few species like Wood Pewee, Red-eyed Vireo, Indigo, 

 Bunting, and Hermit Thrush, which continuing their singing well 

 into August are vigorous singers throughout July. 



The Oven-bird in even-song not infrequently makes the flight 

 song its last utterance. When this is not its last song, it often has 

 been given several times during the final hour of singing. On July 

 7, 1912, three flight songs were given at about ten minute intervals, 

 7.18, 7.27, and 7.37 o'clock. In 1913 on nine evenings out of seven- 

 teen a flight song was the final song and was given at 7.32, 7.35, 

 7.3"), 7.38, 7.43, 7.44, 7.44, 7.56, and 8.01, the variation in minutes 

 after sunset being from 9 to 16, except on the two occasions of 

 latest song, when the rendering of the flight song was 31 and 35 

 minutes after sunset, corresponding in some degree to the quite 

 usual very early song in morning awakening. 



Song Sparrow and Chipping Sparrow at the close of the day also 

 give infrequent repetitious of their songs as their earliest songs in 

 morning awakening are infrequently given. In the case of Song 

 Sparrow in the evening of July 24, 1912, there were but eight 

 repetitions of the song in the last twenty-five minutes of the bird's 

 singing. Chippies sing no hurried trills in the evening as they 

 regularly do in the morning awakening. 



Three records of the Wood Thrush in 1912 average 27 minutes 

 after sunset and 7. .">.") o'clock; the latest is 34 minutes on July 5. 

 On this occasion, as I entered the woods at 6.43, the thrush Mas 

 singing, and he sang much of the time up to his last song a half- 

 minute after S.02, then gave a few calls which ceased at 8.03 o'clock. 



Twenty records of Hermit Thrush average 33 minutes after sun- 

 set and 8.02 for calls as well as the song; the latest are 40 minutes 

 on two occasions when the calls extended to 8.09 and S.10, the song 

 having ceased at 8.07 and 8.05, respectively. On one other even- 

 ing the song also extended to 8.05 o'clock. 



Twenty-five records of the Robin average 33 minutes after sun- 

 set and S.01 for calls as well as song. Calls are usually given for 

 several minutes after the birds have ceased to sing. Sometimes 

 the song ends much earlier. The latest record is 45 minutes and 

 8.15 for last calls, when the song ceased Imt one minute earlier. 

 The variation in time of last note is fifteen minutes, but if the latest
