We report observations of Hooded Crows (Corvus cornix) hanging upside down in the wild, for both playing and harvesting acorns. This behavior was recorded in six different events at the same site (Villa Chigi's urban park in Rome, Italy) and, in two cases, involved two individuals at the same time. Hanging behavior has been observed mainly in captive Northern Ravens (Corvus corax) and in few cases in wild corvids. Our observations indicate hanging behavior can be used to obtain food. These observations confirm that corvids have enormous plasticity that can be adapted to obtain food.
