Conant Creek, Idalio. 



Nearly fresh. 



I found but one uest of Brewer's chipping' sparrow. It was placed 

 on a sage-brush about one foot above the ground, and was composed 

 entirely of the stalks of dry grass, lined with finer pieces of the same. 

 Its external diameter measures 2.80 inches by 2.30 in depth; inside, 

 2 inches broad by 1.60 deep. The eggs are greenish blue, spotted with 

 chocolate brown, the spots being most numerous at and forming a ring 

 around the large end.

This nest was found on a bush in a marsh, about six feet above the 

 ground. It was composed of dry swamp-grass, covered on the outside 

 with dead leaves, with here and there a little green moss. It was cup- 

 shaped, very compact, and was lined with fine stalks of dry grass and 

 hair. It measured about 4.25 inches in external diameter by 2.75 deep. 

 It was 1.90 inches deep inside by 2.30 broad. The eggs were light 

 greenish blue, spotted and blotched all over with dark brown.
