some localities at least, to the earlier part of the night. (About 10 o'clock 

 in the evening is, I think, a favorite time.) The Song Sparrow, however, 

 does often indulge in song in the very early morning, before he gives evi- 

 dence of having awakened for the day. The records of the eleven mornings 

 are as follows : — 



May 14, 1913. Sunrise 4.24. Song Sparrow sang once at 3.24, then 

 was silent till 3.58, when it began to sing continuously. Robin began at 

 3.25. Chipping Sparrow sang at 3.40, then was silent till 3.47, when it 

 began to sing continuously. (This preliminary song was an unusual 

 occurrence in my experience.) 



May 31, 1913. Sunrise at 4.10. Robin singing when I awoke at 3.15. 

 Song Sparrow sang at 3.20 and again at 3.27, and began frequent singing 

 at 3.29. Chipping Sparrow began at 3.35. 



June 1, 1913. Sunrise at 4.10. Robin singing at 3.12, when I awoke. 

 Song Sparrow sang at 3.19 and again at 3.22, and began frequent singing 

 at 3.24. Chipping Sparrow began at 3.32. 



June 19, 1913. Sunrise at 4.07. I awoke at 2.45. Song Sparrow sang 

 once at 2.47; another Song Sparrow sang once at 3.07; first bird sang again 

 at 3.20, then at 3.29; second bird began a song-period at 3.48. Robin 

 began at 2.50 (unusually early). Chipping Sparrow began at 3.29. 



July 12, 1913. Sunrise at 4.18. Robin singing at 3.15 (estimated), 

 when I awoke. Song Sparrow sang once at 3.30. Chipping Sparrow 

 began at 3.35. 



July 18, 1913. Sunrise at 4.23. Awoke at 3. Robin began at 3.42. 

 Song Sparrow sang once at 3.52 and began continuous singing at 3.58. 

 Chipping Sparrow began at 3.56. 



April 10, 1914. Sunrise at 5.12. Song Sparrow began at 4.38. Robin 

 began calling at 4.42 and singing at 4.43. The Song Sparrow on this early 

 spring day thus awoke 34 minutes and the Robin 30 minutes before sun- 

 rise. As compared with late spring and early summer singing, the Robin 

 was late rather than the Song Sparrow early. 



May 29, 1914. Sunrise at 4.11. Robin began at 3.17. Song Sparrow 

 had sung once about 10 minutes earlier but did not sing again till after 3.45. 

 Chipping Sparrow began at 3.33. 



June 10, 1914. Sunrise at 4.06. Cloudy and cold. Robin calling at 

 3.23; began singing at 3.24. Chipping Sparrow began at 3.40. Song 

 Sparrow's beginning later and not noted. 



June 14, 1914. Sunrise at 4.06. Robin began at 3.12. Chipping 

 Sparrow sang once at 3.20, again at 3.26, and began morning song at 3.2s. 

 Song Sparrow sang twice at 3.41; began in earnest at 3.46. 



June 17, 1914. Sunrise at 4.06. Out at 2.45 and listening carefully in 

 all directions about my house for the earliest bird-notes. Nothing heard 

 till 3.13, when Robin began. Chipping Sparrow sang once at 3.20; began 

 in earnest at 3.23. Song Sparrow began at 3.40; another at 3.41. Just 

 before 4.30 the two Song Sparrows were among the more conspicuous 

 singers to be heard. Then- failure to begin singing earlier than 3.40 was 

 evidently not due to any marked waning of the song-impulse. '
