The tail leathers are only moderately graduated on the sides ; the outer about .40 of an inch 

 shorter than the middle. Tlio outer tail leather has the terminal half white, the outline 

 trausverse ; the white of the second is about half as long as that of tlie first ; of the third half 

 that of the second. The chestnut of the sides reaches forward to the black of the neck, ami is 

 visible when the wing? 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, 81'J3, 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.
