The specimens of Jltiffed Clrouse i'rom tlie Pacifie coast dilfer very greatly 

 from others in much darker tints of coloration, altiioiigh the jiattern is 

 ])recisely the same. The ujjper parts are dark orange-chestnut, mottled with 

 black, the cordate light spots very distinct. The feathers of the brea.st are 

 strongly tinged with reddisli-yellow ; those of the sides marked with broad 

 and consiiicuous bars of black, instead of the obsolete brown. The under 

 tail-coverts are orange-chestnut, with indistinct bars of black, and an angular 

 terminal blotch of white. All the ligiit brown l)lotches and edgings of the 

 eastern variety are here dark Ijrown or black. Tiie jugular band between 

 the rutlles is very conspicuously black. S])ccimens from Kastern Oregon and 

 Washington have dark gray tails, ami thus incline toward var. mnhelloiilcs. 



Haiuts. The "Western IJuifed (lrou.se was found aljundant by Dr. Sui'k- 

 ley iu the timbered districts throughout Oregon and Wasinngton Territory. 

 Its habits seemed to be identical with those of the eastern birds. t)wing 

 to the mildness of the season in the vicinity of P'ort Steilacoom, the males 

 commence drumming as early as January, and in Feln'uary they are heard 

 to drum throughout the night. In the autumn they collect in gre.-it num- 

 bers iu the cmb-apjtle thickets near the salt marshes at the mouths of the 

 rivers emptying into Puget Sound. Tiiere they feed for about six weeks 

 on the ri])e fruit of the northwestern crab-apple, the I'ljrm rivularis of 

 Nuttall. 



Dr. Cooper also .ipeaks of this Grouse as very abundant everywhere about 

 the borders of woods and clearings. It was common near the forests east of 

 the Cascade Mountains uj) to tlie 4'.ith degree. These liirds vary in plu- 

 mage there, a ])ale-grayish hue ])redominating. West of the mountains they 

 are all of a very dark brown. There was, however, no ])erceptil)le difference 

 in their htiliits or cries from tliosu of the same liird elsewhere.
