CEOPHLffiUS LINEATUS MESORHYNCHUS (Cabanis and Heine). 



PANAMA PILEATED WOODPECKER. 



Similar to C. I. lineatus '^ but decidedly smaller ; under parts of 

 body much darker brownish buffy with the blackish bars much less 

 regular, often in form of spots rather than bars; throat usually 

 much more broadly streaked with blackish, black areas more sooty 

 (especially remiges), and under side of wing more decidedly yellowish

Adult male. — Pileum and nape (including conspicuous occipital 

 crest) bright poppy red; rest of upper parts plain black, becoming 

 more sooty, or dark grayish brown, on primaries and distal sec- 

 ondaries, the longer primaries indistinctly tipped with paler (except in 

 worn plumage) ; outermost scapulars with outer web and tip of inner 

 web white, forming a broad white stripe along each side of back; 

 a broad stripe of white along side of neck, contracted in width at 

 upper end and thence continued, as a narrow stripe, beneath 

 auricular and orbital regions to nostrils, the post-nasal and loral 

 portions, however, dull yellowish (buff to nearly tawny) instead of 

 white; auricular and suborbital regions and posterior portion of 

 loral region plain brownish slate or slate-gray ; malar region crimson ; 

 chin and throat streaked with white and blackish in variable rela- 

 tive proportion, but usually in approximately equal amount; fore-

 brown, usually with a fairly definite posterior margin but some- 

 times merging insensibly into the paler coloration of more posterior 

 parts; ground color of remaining under parts pale brownish buff to 

 clay color, more or less distinctly barred or spotted with sooty black 

 or dusky; under wing-coverts and basal half (approximately) of 

 inner webs of remiges immaculate buff-yellow (fading into paler, or 

 yellowish white, in old feathers or very old skins); bill dark horn 

 color or dusky, the mandible paler basally; iris light yellow to white; 

 legs and feet dark horn color or dusky (in dried skins), light bluish
