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, 
jdoes 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 
it 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 
it 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 
it 3.20, then at 3.29; second bird began a song-period at 3.48. Robin 
oegan at 2.50 (unusually early). Chipping Sparrow began at 3.29. 
July 12, 1913. Sunrise at 4.18. Robin singing at 3.15 (estimated), 
vhen I awoke. Song Sparrow sang once at 3.30. Chipping Sparrow 
>egan at 3.35. 
July 18, 1913. Sunrise at 4.23. Awoke at 3. Robin began at 3.42. 
!ong Sparrow sang once at 3.52 and began continuous singing at 3.58. 
Shipping Sparrow began at 3.56. 
April 10, 1914. Sunrise at 5.12. Song Sparrow began at 4.38. Robin 
egan calling at 4.42 and singing at 4.43. The Song Sparrow on this early 
pring day thus awoke 34 minutes and the Robin 30 minutes before sun- 
, ise. As compared with late spring and early summer singing, the Robin 
:,ras late rather than the Song Sparrow early. 
May 29, 1914. Sunrise at 4.11. Robin began at 3.17. Song Sparrow 
lad sung once about 10 minutes earlier but did not sing again till after 3.45. 
Shipping Sparrow began at 3.33. 
June 10, 1914. Sunrise at 4.06. Cloudy and cold. Robin calling at 
i.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 
Iparrow sang once at 3.20, again at 3.26, and began morning song at 3.28. 
long 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 
ill directions about my house for the earliest bird-notes. Nothing heard 
ill 3. 13,. when Robin began. Chipping Sparrow sang once at 3.20; began 
n earnest at 3.23. Song Sparrow began at 3.40; another at 3.41. Just 
>efore 4.30 the two Song Sparrows were among the more conspicuous 
lingers to be heard. Their failure to begin singing earlier than 3.40 was 
widen tly not due to any marked waning of the song-impulse.
