Sunlight Likely Powering Oviraptor Incubation, Taiwan Study Finds

Taiwanese researchers built a life-size oviraptor nest to test egg incubation and found that environmental heat, especially sunlight, likely played a bigger role than body warmth, implying a hybrid and less efficient incubation method than modern birds; warmer conditions reduced temperature gaps across the nest, while colder conditions caused up to 6°C differences between inner and outer eggs.
