316 Wright, Morning Awakening and Even-Song. [july 



7. The Wood Pewee's (Myiochanes virens) voice has not 

 always been within hearing. Eight records give the average time 

 of its first song as 3.06 o'clock. The earliest record has been 2.58 

 and the latest 3.12 o'clock. A single singer only usually joins 

 in the concert, and his plaintive song has reached the ear in an 

 occasional way. 



8. The Vesper Sparrow {Pooecetes gramineus gramineus) also 

 comes into the group of birds which sometimes sing before 3 o'clock. 

 The earliest occasion was at 2.49; the next earliest at 2.58 o'clock. 

 The average time of beginning to sing, based on nine records, is 

 3.07 o'clock. Sometimes two birds have been within hearing. 

 The singing is continued commonly for forty-five minutes or an 

 hour without long pauses. 



9. The Hermit Thrush {Hylocichla gidtaia yallasi) invariably 

 calls for a few minutes before breaking into song. When a bird 

 has been located near, the calls have always been first noted; but 

 when the birds are more distant, the song comes as the first voicing 

 heard. Therefore the species has been assigned its place on the 

 basis of the time of its beginning to sing. Three or four singing 

 birds have sometimes been within the range of hearing. The 

 average time of the first call heard, based on ten records, has been 

 3.06 o'clock. The earliest records are 2.56 and 2.59 o'clock. 

 The average time of the first singing is 3.11, or five minutes later 

 than the first call. The song is always continued in the beautiful, 

 calm manner characteristic of the species, first in one of the three 

 registers and then in another with endless variety of change, quite 

 indefinitely; with pauses, to be sure, but it is likely to be heard 

 much of the day, even at noon. At Cherry Pond the first singing 

 »f a Hermit Thrush in the morning was at 3.10 o'clock. 



10. Phcebe (Sayomis pha>hc). The usual time of awakening 

 places the Phoebe tenth among the earliest birds. Ten records 

 furnish the average time of 3.11, when the song has first been 

 heard. The earliest awakenings ha\e been 2.57 and 3.05 o'clock. 

 The song is usually continued without much pause for an hour or 

 more. On June 11, 1904, a near bird broke out demonstratively 

 at 3.10, contributing the Phoebe song of the morning. 



11. Savannah Sparrow {Passcrculus sandwichcnsis savanna). 

 The light voice of this bird is sometimes not near enough to be
