Weight, Morning Awakening and Evensong. 533 



the time of its last song is thus known. And when the record of 

 the evening has been completed, the species are ranked in their 

 true order. The earlier records of the season were begun about 

 6.30, or an hour before sunset; the later about 6.45, or from thirty 

 to forty minutes before sunsetting. A few species always dropped 

 out almost at once. Other species continued their songs for some 

 time, either singing constantly or after intervals of rest resuming 

 their songs. Still others sang from the beginning to the close. 

 All the species which entered into the morning awakening records 

 arc included in even-song, except House Sparrow and White- 

 breasted Nuthatch, a full quota of voices having been heard by 

 visiting the several locations. In the season of 1913 thirty evening 

 records were taken, covering a wider range of location, between 

 June 2 and July S inclusive. These have been combined with the 

 records of 1912 in drawing up the averages presented in the table 

 of even song. Records previous to these two seasons have been 

 only exceptionally retained. 



As stated in the first paper, all these records show that even-song 

 i Iocs not extend as long after sunset as matins precede sunrise. 

 For while the earliest nine singers in morning awakening precede 

 sunrise by an hour to an hour and twenty minutes, the latest nine 

 singers in even song cease singing from twenty-seven to thirty- 

 seven minutes after sunset, a shortening of thirty-five to forty 

 minutes. And it also continues to hold true by the records of 1912 

 and L913 that the order of the awakening, generally speaking, is 

 reversed in the evening. So the flycatchers, the sparrows, and the 

 thrushes are the latest singers, just as they are the earliest in the 

 morning. The thrushes, however, are invariably the last of all, 

 Wood Pewee, Alder Flycatcher, and Scarlet Tanager only ranking 

 with them. Five of the thrushes, Wood, Hermit, Robin, Veery, 

 and Olive-backed, continue to sing from twenty-seven to thirty- 

 seven minutes after sunset. The Bluebird's record does not extend 

 as Lite by ten minutes. Black-billed Cuckoo's, Belted Kingfisher's, 

 and Olive-sided Flycatcher's calls cease about the time of the Blue- 

 bird's song. The Barn Swallow's record is twenty-seven minutes 

 after sunsetting. Five common sparrows, Savannah, White- 

 throated, Vesper, Chipping, and Song, and the two flycatchers, 

 the Least and Phoebe, cease singing just earlier, or from twenty-
