bird, but less common than the Brazilian Cardinal, with which 
it is often associated, both in freedom and captivity. It is said 
to gather in flocks to the number of several hundreds, but I have 
never seen more than three in company, and in such cases the 
adage seemed to be verified, — “Three’s a crowd.” As there is 
no trace of red on the bird the name Yellow Cardinal can hardly 
be justified except on the ground that it is “the name of the 
thing.” 
31. Diuca minor Bp. — A common bird among scattered 
bushes or thickets in comparatively open ground. It disappears 
during the coldest weather, but makes its appearance again in 
little flocks late in July or early in August. These soon scatter, 
and through the summer the male is commonly heard chanting 
a rather short and not particularly pretty song from the top of 
some low bush or from a fence post. The nest and eggs were 
not taken. 
32. Zonotrichia pileata ( Bodd .). Chingolo ; Chingo- 
lito. — By far the most familiar if not the most abundant bird 
of the family. It is resident through the year at Concepcion, 
and also much farther south. It spends most of its time on the 
ground, but I think is never met with in any numbers at a dis- 
tance from shrubs or trees of some kind. The nest is built on 
the ground, usually under a tuft of grass, a thistle, or almost 
anything which will conceal it. In one case I found it placed 
within and beneath the battered rim of an old tin pan beside the 
road. Three eggs are usually laid, seldom four, and never, to 
my knowledge, more ; but the Cowbird ( Molothrus bonariensis ) 
usually adds one or two more and sometimes even four or five. 
More than half the Sparrows’ nests found contained eggs of 
the Cowbird, and quite frequently I found them deserted, 
evidently from that cause. The earliest nest found was October 
4, and from that time until late in December they were constantly 
noticed, sometimes a half dozen in a morning’s collecting. 
Undoubtedly two broods are reared by many of the birds if 
not all. The eggs vary widely in color, but the ground-color is 
always bluish-green, sometimes sparingly and irregularly spotted 
with coarse markings ; at other times profusely and evenly 
sprinkled with minute dots, the markings being different shades 
of brown.
