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.) 45. MACROPYGIA PHÆA McGregor. DARK CUCKOO DOVE. Macropygia phæa McGregor, Bull. Philippine Mus. (1904), 4, 9; Phil. Jour. Sci. (1907), 2, sec. A, 338; McGregor and Worcester, Hand-List (1906), 13. A-la-gá-dang, Calayan. Batan (McGregor); Calayan (McGregor). Adult.--Similar to Macropygia tenuirostris but larger and darker; cinnamon edgings on inner primary webs and rufous edging of wing-coverts narrower or obsolete. The sexes differ as in the preceding species. Male (type).--Bill brown with reddish base; legs dark reddish brown; nails brown; iris of three rings, outer crimson, middle black, inner straw. Length, 413; wing, 198; tail, 198; exposed culmen, 18; tarsus, 24. Female (type).--Colors of bill, legs, and eyes as in the male. Length, 406; wing, 196; tail, 195; exposed culmen, 18; tarsus, 22. This species is rather abundant in Calayan; in habits it does not differ from Macropygia tenuirostris. The species is rare in Batan, Batanes, where a nest containing one egg was taken, June 12. The egg is pure white and measures 37 by 27. Family PERISTERIDÆ. Tarsus slender and unfeathered; bill slender and weak, gape small, nostril covering swollen; tail slightly graduated; colors plain or brilliant; size moderate. Subfamilies. a1. Plumage mostly brown, gray, and vinous; very little if any metallic color.
