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 this Halloween season podcast, Ari Daniel Shapiro journeys to Austria to learn how such social learning happens in a spooky bird—the raven. Image Credit:

Same bird as in XC454467. Source: Lisa Rae McMaster, Portland Oregon, with permission. Recording obtained from video (https://youtu.be/Fm5WwH07NfM), with online audio converter (https://online-audio-converter.com/). Audio normalized to maximum amplitude -3.0 dB with Audacity. Observer notes: "‘My’ scrubby has been coming around for the last 7 or so years (only one to feed from my hand) and I swear this is the first time he/she has ‘sung’ to me. It’s been happening for the last few weeks...." "It’s so weird because I have been feeding this bird almost daily for years and have never noticed these sounds..." " I actually just found an old video on my phone dated 2010...so I’ve had a relationship with this bird for 9 years..."
