Some eggs of the West-American Tree-Sparrow resemble those 
of S. monticola, but the majority of those in the Collection are 
more brightly coloured and in some clutches the markings are much 
larger. The ground-colour is pale green, spotted and mottled with 
bright reddish-brown, the markings being often dense and confluent 
at the broad end, where they sometimes form an imperfect cap. 
Underlying the surface markings are many smears and clouds of 
purplish-grey. Eggs of this species, if all are correctly identified, 
vary greatly in size. The larger ones closely resemble the eggs of 
Zonotrichia leucophrys and its allies and should possibly be referred 
to one of those species. They measure from ‘7 to °86 in length, and 
from °55 to *63 in breadth.
