Quoth the raven

Christine Schwab offers the raven Astrid a treat.

We humans learn some of our earliest life lessons from our brothers and sisters, watching what toys our siblings play with and what treats they stash away for later. In Austria, a biologist is investigating how such social learning happens in a bird — the raven. This story is from the audio series One Species at a Time.
