Some Butterflies Are Secretly Cannibals

The video explores unexpected behaviors in butterflies and cockatoos. Butterflies, particularly milkweed species, have been observed feeding on caterpillars, possibly for alkaloids. This behavior was discovered accidentally by scientists in Indonesia. The video also highlights a study on Goffin's cockatoos, which use a set of tools to access seeds from a tropical fruit, showcasing advanced cognitive skills. Both studies reveal surprising survival strategies in these animals, prompting further research into their behaviors.
