Harris’s Sparrow 363 
and a number of dark, purplish-brown, zigzag lines, 
principally at the hinder end. They vary very much 
in size, but average ‘80 x °70. 
Morrison found this bird nesting in trees and bushes 
twenty feet up, in the Arkansas Valley near Fort Lyon, 
where the ground was liable to be flooded. 
Genus ZONOTRICHIA. 
Medium to rather large Sparrow-like birds, with small, conical bills, 
and with nostrils, partly at any rate, concealed by bristles; wings 
fairly long and pointed, but the difference between the primaries and 
secondaries less than the tarsus; the ninth (outer) primary about 
equal to the fifth or fourth, the intervening sixth to eighth being the 
longest ; tail long, nearly or quite equal to the wing, always above 
‘90 of the wing, slightly rounded or double rounded; plumage with 
streaky back, and a crown either wholly or partially black. 
As restricted by Ridgway, this genus is confined to North America, 
including Mexico. Of the six recognized forms no less than five have 
been found in Colorado, but only two of these are at all commonly 
met with.
