"Mr. McGregor further states that on these islands “the San Benito Sparrow 
far outnumbers all other land birds taken together.”” He examined three dif- 
ferent nests, all of which were placed on the ground under small bushes. 
One found on March 30 contained three eggs. It ‘* was sunken level with the 
ground, which served to support the thin walls. The outside is of large grass 
straws while the lining is of finer grass and a few feathers. The three eggs 
measure respectively .83 X .58, .82 X .61, .81 X .60. They were slightly incu- 
bated [when taken on Aptil 1]. They are well marked all over with flecks 
and blotches of umber brown on a ground color of faint bluish white. One 
egg has one or two blackish hair lines on the large end.”

The birds collected by Mr. Frazar have rather stout bills for bimaculatus, but 
they are typical of that form in respect to coloring and to the relative lengths 
of their wings and tails. 
Mr. Belding gives this sparrow as “ rare,” but states that he saw it in several 
localities. Mr. Frazar took only four specimens, two at San José del Cabo on 
October 21 and 27, respectively, and two at Triunfo on December 5 and 15. 
No one else has reported the bird from the Cape Region, nor does it seem to 
have been detected elsewhere on the Peninsula. It has occurred at various 
places in California, and in the summer of 1875 was found by Mr. Henshaw 
breeding at Santa Barbara directly on the coast. Most of the birds which 
visit Mexico and Central America in winter are said to be passerinus, but 
Salvin and Godman mention! a Mexican specimen which is “as pale as 
another, marked by Mr. Ridgway himself as C. perpallidus.”
