"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."

 Mindoro. Four males average, 445 in length; wing, 167; tail, 268;

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.
