The eggs of the Chingolo Song-Sparrow resemble those laid by 
the species of the genus Zonotrichia. The ground-colour varies from 
bluish- or greenish-white to a pale blue. The markings are dull 
brick-red and vary considerably. Some eggs are only very faintly 
speckled, while others are thickly covered with spots and blotches 
which cover more than half the shell, and between these two types 
there are numerous intermediate forms, Many specimens are fairly 
evenly marked all over, others have the markings more thickly 
disposed at the broad end, where they form a zone or cap, Many
