Adult male.--Head, sides of neck and breast, and lower parts bright

cinnamon-rufous, much lighter on throat and chin, darker on flanks,

under tail-coverts, and rectrices; above including wings and tail

dark brown; most of the feathers except remiges and rectrices,

edged with fine rufous dots; feathers of neck covered with irregular

vermiculations of rufous and blackish brown; sides of neck and of

body and crop marked with a few black cross-lines; neck and its sides

glossed with amethystine changing to green; metallic colors extending

faintly onto back and rump; rectrices from above dark brown, except

two outermost pairs which are cinnamon-rufous, each crossed by a

diagonal black bar; next pair similar but more obscurely colored;

inner webs of primaries edged with cinnamon. Iris of three rings,

outermost reddish or crimson, middle ring black, innermost pale

straw; skin around eye dirty brown; eyelids and basal half of bill

crimson; distal end of bill brown; legs and feet bright crimson;

nails brown. Length, about 394; three males average, wing, 189; tail,

200; exposed culmen, 16; tarsus, 23.

Adult female.--Nearly like the male but with very little if any

metallic gloss; neck and its sides black, barred with light cinnamon;

crop and lower throat more or less barred and vermiculated with black.

Young.--A young bird from Sibuyan with tail less than half grown

differs from the adult female in the throat- and breast-feathers being

blackish brown, edged with rufous, and in having bars of upper parts

more sharply cut, being produced by solid colors rather than by dots;

the rectrices seen from above have narrow rufous tips and from below,

each is crossed by a narrow, subterminal gray line.

The adult plumage is here described from a pair of birds taken at

Irisan, Benguet Province, on May 1, 1903. That these were breeding

birds was shown by dissection and was noted on the tags. If the

rusty edges are absent from the wing-coverts of fully adult birds

then it must require two or possibly three years for them to attain

that plumage.

"Exceedingly common in some localities. Frequents open ground

surrounded by patches of second growth. When flushed it frequently

alights in trees. Eyes yellow; legs and feet red. Length, 370;

culmen, 19; wing, 165; tail, 184; tarsus, 22; middle toe with claw,

33." (Bourns and Worcester MS.)

"Common among the mountains of north Luzon, and found nesting on

the summit of Monte Data, where the large tracts of dead bracken

ferns afford it good protection. I saw a young one nearly ready

to fly on 28th of January on this mountain. This dove is also

plentiful in the lowland forests, and is distributed throughout the

Archipelago." (Whitehead.)
