RED-BILLED PIGEON. 



Adult male. — Head, neck, chest, and breast plain purple-drab, 

 usually duller (sometimes decidedly grayish) on pileum, often deeper 

 (deep livid brown) on hindneck, much paler (pale grayish vinaceous 

 to dull vinaceous-white) on chin and upper throat; back, scapulars, 

 and proximal secondaries and greater wing-coverts, uniform deep 

 hair brown or light fuscous; rump and upper tail-coverts clear bluish 

 gray (between slate-gray and plumbeous), the tail similar but darker 

 (dull slate color to dark neutral gray); smaller wing-coverts (for 

 greater or less part) ° vinaceous-brown or livid brown, those not 

 thusly colored clear bluish gray; greater coverts bluish gray, the 

 outermost (distal) coverts narrowly edged with white (distally at 

 least); secondaries similar but darker and duller (less bluish), very 

 narrowly and indistinctly edged with paler; primaries gray (nearly 

 neutral or light neutral gray), narrowly edged with whitish, at least 

 on longer quills; abdomen, sides, flanks, and under wing-coverts 

 plain bluish gray (somewhat lighter than color of rump), the axillars 

 and under wing-coverts similar but slightly paler; terminal half 

 (more or less) of bill whitish to pale horn color, the basal half (includ- 

 ing cere) light pink to rosy red; eyelids lake red or carmine; iris 

 orange-yellow to reddish orange; legs and feet lake red; length 

 (skins), 320-347 (335); wing, 180-198.5 (192.4); tail, 105-127 

 (118.7); culmen, 13-16 (14.3); tarsus, 23-28 (25.8); middle toe, 

 28-31.5 (29.8). 6 



Adult female. — Similar in coloration to the adult male and not 

 always distinguishable, but usually slightly duller, with pileum more 

 grayish, and reddish brown patch on lesser wing-covert area more 

 restricted; smaller; length (skins), 300-370 (329); wing, 184.5-207 



° Sometimes the entire lesser covert area, except along margin of the wing, is of 

 this reddish brown color, but occasionally the greater part of the area is bluish gray, 

 there being much individual variation in this respect. 



* Fifteen specimens.
