24 Joint Bulletin 2 



October 1, my pet sparrow mounts to his perch and bursts into 

 song, the last time I hear him this season. 



October 21, song sparrow in lane — latest date. 



Fall Records fob 1914. 



September 15, young song sparrows in "The Bottomless Basin" just 

 able to fly. This is the latest record for young birds that I have. (Prob- 

 ably third brood). 



September 16, song sparrows about the premises become shy, hiding 

 in the stone and wood piles. Are quiet and attract almost no attention. 



September 22, song sparrow running in the garden paths and eating 

 alyssum and mignonette seeds. 



September 23 to 26, saw from 4 to 10 sparrows daily about the 

 premises and in the lane. 



October 10, beautiful, warm day, song sparrow in full song, sur- 

 passingly sweet. 



October 20, my pet sparrow still living in woodpile. 



October 24, latest date for the sparrow this year. Often it is seen 

 late in November. 



Nests. 



Description of nest found June 7, 1915: In bush one foot from 

 ground, made of grass stems, dry leaves, lined with fine grass and a few 

 fine roots. Depth of nest about 4 inches on outside, 2*4 inches on inside. 

 Five eggs, light bluish green, wreathed with rufous brown, pretty well 

 spotted all over. 



Time of Nest Building. 



From observations on my garden birds I draw the following gen- 

 eral conclusions: Nest building about one week, probably varies a day 

 or two from that. I think the female does the greater share of the 

 work, as surely the male spends much time singing. 



Incubation about two weeks. 



Young birds in nest about two weeks, also. 



Parents accompanying young about one week.
