Oviraptor modernus is normally a gentle herbivore and mainly feeds on leaves, fruits, shrubs, nuts, seeds, roots, tubers, and bulbs, but can also feed on insects, fish, and, rarely, carrion to supplement its diet. Despite its genus name and its meaning, Oviraptor modernus does not feast on eggs of other dinosaurs, unlike how popular media showed. It is almost entirely covered in feathers, making it resemble a large ground bird, and like many ground birds, Oviraptor modernus is a social animal and lives in flocks up to about 7-13 members in a single group. During mating seasons, the throats and wings of male Oviraptor modernus turn red and they use these bright colors to intimidate each other until one looses, and the winner gets a right to mate. The eggs are laid around 1-2 months after mating seasons, the eggs hatch around 2-3 months after being laid, and the young are cared for by their mothers until they are old enough to fend for themselves.
