In this video from Nature, researchers test whether crows have the ability to pass information on to other crows as well as their young. The study focuses on several crows and tracks them through their first year of life. In the experiment, researchers wear a mask signifying danger and track how the crows communicate that danger to one another and to their young. They then try to discover if the young crows will use the information and remember the "dangerous" face in the future once they have left the nest.
This video is available in both English and Spanish audio, along with corresponding closed captions.
