The inhambu-guaçu (Crypturellus obsoletus) is a forest tinamídeo inhabiting the Atlantic forest in Brazil, in almost all altitude levels, and its most powerful presence above 400 m. In South America occur some subspecies. Occurs in the Brazilian states of Bahia (southern end) to Rio Grande do Sul.
Is between 28 and 32 cm. The general females are slightly larger and have more reddish hue of color. It has very strong vocalization ascending scale, with the longest female to male vocalization. Also emit different piados warning and socialization. Commonly, during the female vocalization, males interleave piados the corner.
The geographical race Crypturellus griseiventris obsoletus, also called inhambu-poca-bamboo, occurs in Brazil in the Amazon region; showing little difference as to the general color; especially the belly and head and beak more gray little longer. But well differentiated vocalization, remembering vaguely of C. obsoletus obsoletus, the Southeast and South of Brazil. Amazon also occurs in another geographical race, oCrypturellus obsoletus hypochracea.
It feeds on seeds, small fruits, insects and worms.
Mates from September to December. Its nest on the ground is very little developed, based on some dry leaves, under some foliage or beside some trunk; and your posture is to 2-3 eggs of pink-purple color, incubated an average period of 19 days by the male.
It is found in primary forest, in stretches of dense vegetation and undergrowth, and secondary forest. Given the significant reduction in the areas of primary Atlantic Forest, replaced by secondary forests and pine and eucalyptus plantations (containing understory of native forest), the inhambuguaçu showed a large population growth in recent decades, due to the greater availability of suitable habitat. Rather turn the other tinamídeo as macuco (Tinamus solitarius), which occurs exclusively in the Atlantic Forest Elementary.
