Life History, Abundance, Activity, and Special Behaviors
The species is arboreal and nocturnal, and occurs in continuous forest. Males mainly call at night from perches that vary from 0.5 - 4 m in height. Clutches contain about 33 eggs that are deposited in small bodies of water formed in epiphytes, terrestrial bromeliads, bases of Mauritia palm leaves, and holes in trees. Tadpoles develop to metamorphosis in the water bodies in which the eggs were deposited. Females return to the deposition sites at intervals of about five days and, usually in amplexus with the same male, produce eggs that serve as food for the tadpoles.

Osteocephalus taurinus has separate vocal sacs on each side of the head, and adult O. taurinus are twice as long as adult O. oophagus.
