Birds of Celebes: Cuculidae. 
cinnamon), closely mottled with sooty, the flanks and under tail-coverts almost entirely 
of this colour (near Manado, 0 10872). 
D. Male with earliest appearances of adult plumage. Head, hind neck, and some sprouting 
feathers in the tail blue-black; rest of upper surface very dark glossy green, the 
quills with blue reflections; a pale stripe from rictus to side of neck; chin and throat 
hlacldsh, passing into brownish green on chest; rest of under surface sooty brown, 
varied with cinnamon, especially on the breast and upper abdomen (Manado, 0 1844). 
Three other [cf] specimens, apparently . slightly less developed, have the tail, 
like the back, very dark green, with greenish or bluish reflections; the cinnamon 
colour greatly predominating on the under surface and the long rictal stripe of white 
varied with cinnamon or brown broader and more distinct. 
E and e. First plumage and Q]. Above dark glossy green, uniform, approaching to black 
on the head, chin and throat dusky; rictal streak of fulvous white passing into the 
cinnamon-brown of sides of neck; under surface cinnamon, each feather crossed with 
two or three fine brace-shaped bars of dusky (C 5181 and three others). In one the 
bars on the under surface are quite absent (C 1843). Tail-feathers of the two others 
obscurely barred with dark cinnamon (C 263, C 1845). Bill in C 5181 dark horn- 
brown, under mandible paler; in C 263 and 1845 darker horn; in 1843 black. 
Nestling, Plumage uniform above, apparently similar to the above, and below similarly 
cinnamon with brace-shaped bars (Tomohon, 15. IV. 94: P. & P. Sarasin). 
c. Female with earliest appearances of adult plumage. Head, neck and mantle bluish black, as 
in male with earhest appearance of adult dress (see supra]', hack and wing- coverts 
varied with somewhat obscure bars of rufous brown (cinnamon-hazel); wings comjDOsed 
of old dusky feathers, uniform as in the young, and of new ones (some of them 
sprouting) crossed with cinnamon-hazel and black bars, the black ones a little the 
broadest; tail similarly composed of new feathers — some of them growing — barred 
with cinnamon-hazel and black, one old feather is dusky with the cinnamon markings 
very obscure; chin and throat black, slightly touched up with wlntish brown; rictal 
streak white; under surface fulvous cinnamon, crossed with narrow brace -shaped 
blackish bars. Bill blackish horn-colour (near Manado, 0 10869). 
From the circumstance that the third and fourth quills of one wing and .the 
third and fifth of the other are old feathers, but are nevertheless considerably marked 
with imperfectly-formed bars of cinnamon in their basal two -thirds, we. infer that 
this specimen may be a second-year bird passing into its third phase of dress. The 
quills, in what we take to be young specimens in first plumage, are uniform, but 
perhaps our four young ones are all males. Another [$] specimen (0 266), appa- 
rently of the same age as the above is somewhat more melanistic in character. 
b. Female a little older. Like the last, but with no remains of a younger dress. Head, 
neck and mantle bluish black; rest of upper surface evenly barred with cinnamon- 
hazel and black; chin and throat black; below fulvous cinnamon, finely barred with 
dusky (near Manado, C 10871). 
a. Adult female. Like the last, but with the head, neck, clnn and throat cinnamon -hazel 
with dusky edges to most of the feathers, giving a somewhat streaked appearance; 
the cinnamon -hazel bars of the upper surface much broader than the black ones 
(Q, Kema, 7. Aug. 93: P. & F. S.). In C 3581 the bill is dark horn-colour, the under 
mandible paler; in C 10870 almost all black. 
Three other specimens afford transitions between the immature stage b and the 
adult stage a (N. Celebes, C 265, 5183, 264).
