BIRDS—FRINGILLIDAE-PIPILO OREGONUS. 
513 
The tail feathers are only moderately graduated on the sides ; the outer about .40 of an inch 
shorter than the middle. The outer tail feather has the terminal half white, the outline 
transverse ; the white of the second is about half as long as that of the first; of the third half 
that of the second. The chestnut of the sides reaches forward to the black of the neck, and is 
visible when the wings are closed. 
A young bird has the prevailing color reddish olive above, spotted with lighter ; beneath 
brownish white, spotted thickly with brown. 
In most western specimens the white of the base of primaries is connected with that on the 
middle so as to have the entire edge of these quills white. One specimen, 8193, from Fort 
Leavenworth, has a few white spots on the scapulars only, the wing coverts without them, 
exhibiting an approach to P. arcticus. This is probably a hybrid between the two.
