FEEDING HABITS OF THE CHIPPING SPARROW 1 03 



The above record will give a fair idea of the activity of these 

 parents during the day. Between 5 and 6 o'clock food was 

 brought fourteen times; between 6 and 7, seven times; 7 and 

 8, eleven times ; 8 and 9, twelve times ; 9 and 10, ten times ; 10 

 and II, seventeen times; 11 and 12, ten times. The after- 

 noon hours were equally well filled. During the first hour (12 

 to i) fifteen visits to the nest were made, while the second hour 

 saw twenty-one visits recorded. Between 2 and 3 the parents 

 came twelve times ; between 3 and 4, nine times ; between 4 

 and 5, thirteen times ; between 5 and 6, nine times ; between 6 

 and 7, ten times. The day's work closed at 7 :5o, when it 

 was too dark to see the late worm should he still be wandering 

 about.

 above and at the end of the bulletin :

6 :i7 — The female (?)• returned, fed, and flew away. 

 6:28 — One parent returned, fed, and flew away. 



6:34 — One parent returned with a large, green worm ; the nestling 

 to which it was given had considerable difficulty in swallow- 



ing It. 



6:39 — One bird returned with some small insect. 



6 :44 — One parent brought a small, dark-colored larva resembling 



that of a saw-fly. 

 (A man working a lawn-mower near the nest was probably 



the cause of this interval of sixteen minutes.)
