BIRDS OF NORTH AND MIDDLE AMERICA 



365 



Large and stoutly built very short-tailed Odontophorinae (wing about 

 127-158 mm.) with short tail (less than half as long as wing), large 

 and stout feet (tarsus nearly one-third as long as wing, sometimes 

 slightly longer), heavy bill, more or less extensively naked orbital region, 

 and feather of posterior portion of pileum more or less (but not con- 

 spicuously) elongated, forming, when erected, a bushy crest of broad, 

 round-tipped, decurved or decumbent feathers ; sexes alike in coloration. 



Bill relatively large and heavy, the chord of exposed culmen (from 

 extreme base) equal to two-fifths to nearly half the length of tarsus, the 

 depth of bill at base greater than distance from anterior end of nasal 

 fossa to tip of maxilla and equal to or greater than its width at rictus; 

 culmen strongly convex, rounded, narrower and more ridge-like basally. 



Figure 20. — Odontophorus gujanensis. 



Outermost primary equal to or slightly shorter (sometimes much shorter) 

 than ninth (from outside), the third, fourth, and fifth, fourth, fifth and 

 sixth, or fifth to eighth longest. Tail two-fifths to nearly half as long 

 as wing, mostly concealed by coverts, the rectrices (12), however, firm, 

 broad, with rounded tips. Tarsus nearly one-third as long as wing, 

 sometimes more than one-third as long, nearly to quite as long as middle 

 toe with claw, very stout, the planta tarsi, on both sides, with a continuous 

 row of transverse scutella (larger and more continuous on outer side). 

 Plumage and coloration. — Feathers of pileum elongated, broad, soft, 

 and flattened (webs not conduplicate), forming, when erected, a bushy 

 crest; orbital (sometimes also loral) region more or less extensively 

 naked. Coloration dull, various tones of brown or brown and rufous
