replaced by glossy bottle green; chin, throat, and malar region like the 

 forehead but with a little more blue in the sheen and the lower throat 

 becoming bottle green; a complete (usually) white collar around the base 

 of the neck separates the head and neck coloration from that of the body 

 although in some cases the bottle green continues on the middorsal area 

 for a very little distance posterior to the collar ; interscapulars with their 

 exposed portions bright buff yellow with a terminally widening median 

 wedge of bright blue-green black and with edgings of the same, but slightly 

 duller and narrower ; from the base of the median wedge-shaped marks 

 a fuscous to fuscous-black band goes off toward the sides of the feathers 

 in a posteriorly pointed diagonal, leaving a large, white, terminally pointed, 

 triangular space in the center of the feather ; the basal half of the feather 

 dull sepia; in the lower (posterior) interscapulars, the so-called hackle 

 feathers, the white triangles are transformed into bands of white with 

 median fuscous shaft marks and extend into the visible pattern of the 

 overlapping feathers, largely replacing the buff-yellow ; these posterior 

 interscapulars also have the bright green terminal median wedges re- 

 placed by dark fuscous (the whole interscapular area varies greatly 

 according to the amount of P. c. colchiciis blood in the strain, the buff- 

 yellow becoming more tawny or orange-tawny, the bottle green more blue- 

 black in birds with a larger amount of pure colchicus blood in them) ; 

 scapulars and inner greater and median upper coverts Kaiser brown to 

 Hay's russet with a terminal light magenta gloss and with large white 

 to light buff centers edged with black and sometimes mottled sparingly 

 with the same ; lesser inner upper wing coverts with the russet borders 

 narrow or missing, leaving the feathers white bordered and centered with 

 fuscous to fuscous-black ; rest of upper wing coverts light gull gray to light 

 neutral gray, paling to white at the bend of the wing; long innermost 

 greater coverts and the long scapulars neutral gray much tinged with 

 pale olive-buff and broadly edged, but not tipped, with Hay's russet (in 

 birds with more colchicus than torquatus blood all the gray feathers are 

 olive-buff, sometimes almost buffy brown, and the russet edges are heavily 

 washed with purplish) ; secondaries pale buffy brown, incompletely barred 

 along the basal half or more of the shaft with backward-pointing, diagonal, 

 white, wavy bars, which are narrowly edged with dusky buffy brown, 

 these marks not showing in the folded wing and sometimes almost be- 

 coming longitudinal wavy marks running toward the base of the feathers; 

 the innermost secondaries with narrow lateral edgings of Hay's russet ; 

 primaries darker and more grayish, less buffy, brown and crossed on both 

 webs with wavy whitish bars except on their terminal portions ; upper 

 back like the scapulars, but with the white centers medially marked with 

 deep bottle green ; back, lower back, and rump greenish glaucous to deep 

 lichen green, laterally and posteriorly extensively tinged with glaucous- 

 gray ; the feathers of the median part of the back and lower back with
