CYANOCITTA STELLERI STELLERI (Gmelin). 

 STELLER'S JAY. 



Adult male. — Head (including crest), neck, and upper portion of 

 chest, plain black or sooty black, the forehead usually more or less 

 streaked with blue (cerulean or azure) and chin and upper throat 

 usually more or less streaked with pale grayish; back and scapulars 

 plain dark sooty brown (less brown or more slat}' in fresh plumage); 

 rump and under parts posterior to chest blue, varying from greenish 

 blue (china l)lue) to a less greenish hue, the upper tail-coverts similar, 

 but brighter (almost cerulean blue); wing-coverts and primaries dull 

 cerulean or sevres blue, the greater coverts usually with narrow (some- 

 times indistinct) bars of black; secondaries deep cobalt or dull ultra- 

 marine blue, with four to six innermost ones (including tertials) marked 

 with sharply defined (usually very distinct) curved bars of black; tail 

 dull cobalt blue, with terminal portion usually distincth' l)arred with 

 black and with indications of bars farther toward base: bill, legs, and 

 feet black; iris brown; length (skins), 282-317 (800.2); wing, 114-100.5 

 (151.5); tail, 133-150 (138.6); exposed culmen, 27.5-32 (31); tarsus, 

 41.5-50.5 (46.5); middle toe, 22.5-26 (24.7).'^

 able, but usually slightly smaller, with black bars on secondaries and 



« It is exceedingly difficult to draw the line satisfactorily between this form and 

 C. c. cristnfa, for the reason that, as in similar cases, there is a gradual transition 

 between the extremes. After carefully examining, comparing, and measuring a 

 very large scries, however, it seems that there is upon the whole more difference 

 between Florida specimens and those from other Southern States than between the 

 latter and northern exami)le&. This is no less true of coloration liian nf size. (See 

 average measurements imder C. cristata, on page 348, footnote.)
