BIRDS — PKINGILLTDAE — PIPILO OEEGONUS. 



)13 



The tail feathers are only moderately graduated on the sides ; the outer ahout .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 ahout 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 hlack 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.
