Young.--A young male taken May 11 is blackish brown; head and neck glossed with green; chin, throat, and breast mottled with gray; wings faintly glossed with green; primaries and secondaries slightly tipped with dull rufous; alula and all upper wing-coverts barred with dull rufous; tail black strongly glossed with green. Wing, 160; tail, 180; culmen from base, 29.
Grant gives the following description of an immature male:
"The immature feathers in the upper parts are dull brownish black, devoid of any gloss; the immature tail- and flight-feathers are similarly colored, but slightly glossed, and the latter are indistinctly barred with pale rufous on both webs. The throat, breast, and belly are brownish black, indistinctly marked with buff; the rest of the plumage is similar to that of the adult."
"Frequents bushes in open fields like C. viridis. Very common in Mindoro. Four males average, 445 in length; wing, 167; tail, 268; culmen, 37; tarsus, 35; middle toe with claw, 40. A female measures, 476 in length; wing, 176; tail, 279; culmen, 32; tarsus, 42; middle toe with claw, 42. Iris red; bill, legs, and feet black. Food insects." (Bourns and Worcester MS.)
The Mindoro coucal builds a bulky globular nest of grass, with an entrance on one side. A nest found in April was situated in a thick bed of giant grass. The two eggs are dull white and covered with a thin layer of a white, chalky substance; their measurements are 27.4 by 21.8 and 24.3 by 21.

"Sexes alike.--Forehead, crown and nape, sides of face, chin, throat, and upper breast greenish black; the coarse shafts of the feathers shiny black, the webs with a faint greenish tinge; hind neck and back, sides of neck, wing-coverts, and breast smoky brown with faint greenish tinge; hind back and rump slaty black, tips of feathers with greenish tinge; upper tail-coverts and upper surface of tail uniform dull metallic green; shafts of feathers jet-black from base to tip; upper surface of wings earthy brown with metallic green gloss like the tail, except on the four outer primaries, which have little gloss; abdomen browner than breast and with less metallic wash; flanks, thighs, and under tail-coverts like rump; under surface of tail black with faint metallic blue gloss; under wing-coverts and axillars like breast; under surface of wing uniform blackish brown. Seven males measure as follows: Length, 424; wing, 150; tail, 216; culmen, 40; tarsus, 42. A female measures, 495 in length; wing, 158; tail, 233; culmen, 44; tarsus, 43." (Bourns and Worcester.)
Steere's coucal is somewhat like the Mindoro coucal but its breast and neck are smoky brown while the entire plumage of the Mindoro coucal is black glossed with green. The two species are fairly abundant in Mindoro and inhabit thick grass patches and jungle.
