In mythology, crows can indicate both good and bad omens, depending on the number of crows and the context. A single crow is often thought to be a bad omen, but seeing two could indicate good luck is eminent. Seeing three suggests impending change. In fact, in many cultures and folklore crows symbolize transformation, especially spiritual and emotional change. The Vikings believed crows could serve as intermediaries between the mortal world and the divine, allowing them to access insights from otherworldly sources. Here, in Amsterdam, crows are very much urban creatures and city dwellers, just like their fellow feathered friends the doves, sparrows, great tits, and parakeets.
