YELLOW-CHEEKED PARROT. 



Adults {sexes alike). — Forehead (broadly) and greater part of 

 lores dull veiTnilion or bright nopal red; lower portion of lores, rictal 

 region, and suborbital region chrome yellow (rarely red, like forehead 

 and lores); crown and occiput with feathers banded with light 

 yellowish green (on middle portion) and lavender or light lavender- 

 violet (subterminally), and narrowly margmed at tip with black, 

 the feathers sometimes pale purplish red or pinkish basally (this 

 concealed) ; hindneck clear parrot green, the feathers rather broadly 

 margined terminally with black, this sometimes preceded by a narrow 

 subterminal bar of lavender or hght lavender- violet; general color 

 of upper parts clear parrot green, the scapulars and interscapulars 

 indistinctly margined terminally with black; four outer secondaries 

 with outer webs pure poppy red for greater part, the distal portion 

 blue-black or black tinged with dark violet-blue, sometimes with a 

 narrow edging of green or hghter blue; basal half (approximately) 

 of primaries clear parrot green, the distal portion blue-black or very 

 dark violet-blue, their inner webs black or slate-black; distal third 

 (more or less) of tail clear light yellowish green, the middle pair of 

 rectrices mostly (sometimes wholly) green; inner webs of rectrices 

 with the darker green proximal portion passing into dusky toward 

 inner edge, those of the two outermost rectrices becoming light yellow 

 basally and, usually, with a more or less distinct subbasal spot of 

 red;" suborbital region (broadly), lower part of loral region, and 

 rictal region yellow (chrome yellow to light cadmium) ; auricular 

 region, malar region (except upper anterior portion), and sides of 

 throat (sometimes whole throat) clear bright yellowish green, the 

 throat often intermixed or suffused with pale red; under parts lighter 

 green, or more yellowish green, than upper parts, the feathers of 

 chest and breast more or less distinctly margined terminally with black 

 (except in worn plumage), the throat sometimes more or less inter- 

 mixed with red; smaller under wing-coverts light yellowish green, 

 those along carpo-metacarpal edge more yellowish (sometimes green- 

 ish yellow); under primary coverts dull green (malachite), pass- 

 ing into pale greenish yellow terminally and on edges (partly) ; under 



o There is great variation among specimens which do not otherwise differ materially 

 in the coloration of the lateral rectrices. Sometimes the red is so much reduced in 

 extent as to amount to a mere trace, while, more rarelj^ it is wholly absent. Occa- 

 sionally the red invades the outer web also.
