CYANOCITTA STELLERI PERCONTATRIX van Rossem
NEVADA CRESTED JAY
ОглавлениеA. J. van Rossem (1931) obtained four specimens of crested jays in southern Nevada, three from the Charlestons and one from Sheep Mountain, to which he gave the above scientific name and which he describes as “similar in head markings and in general body coloration to Arizona, New Mexico, and Colorado specimens of Cyanocitta stelleri diademata (Bonaparte), that is with the supra-orbital region extensively white, the lower eyelid narrowly white and frontal streaks white or bluish white, but differing from that form in having the back and sides of neck ‘deep neutral gray’ (color terms in quotations from Ridgway, Color Standards and Color Nomenclature, 1912) instead of ‘mouse gray.’ Differs from Cyanocitta stelleri annectens (Baird) of the northern Great Basin in decidedly paler coloration throughout, more extensively white eyelids and longer crest.”
He gives the known range as “Transition Zone in the Sheep and Charleston Mountains, Clark County, Nevada.” This race seems to be closely related to the long-crested jay, which it probably resembles in habits.
