AI interpretation · Mobbing alarm

Mobbing calls are the rough opposite. When a hawk slides overhead or an owl is spotted at noon, crows recruit each other into a chorus of compressed, urgent caws — tightly packed in time, spectrally rough, audibly stressful. Kevin McGowan's Cornell field studies catalogued these recruitment chains: one bird sees, calls; three arrive; ten more follow. Some flocks remember and re-mob the same individual predator for years. Our one mobbing recording captures a textbook moment — a small group screaming down from a cottonwood at a human who got too close. The cluster sits high in the embedding space, separated from territorial by call rate alone.
