colored, but slightly glossed, and the latter are indistinctly barred with 
pale rufous on both webs. The throat, breast, and belly are brownish

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.
