Ravens vs Crows: How to Tell the Difference?

Physical Adaptations: Ravens vs Crows

Ravens boast a larger size and a higher wing aspect ratio, letting them soar and glide effortlessly. This efficient flight style conserves energy. Contrastingly, crows have shorter wings which afford them swift and agile flight, an advantage in bustling urban settings. Ravens’ feet, longer with extended talons, help them grip bigger prey and perch on rugged terrains like cliffs. Crows, with their compact feet, handle varied terrains from branches to pavements with ease.

Historical Coexistence with Humans

Throughout history, ravens and crows have coexisted with humans. Crows, adapting remarkably well to urban settings, have become a common sight in cities worldwide. They utilize human-made structures for nesting and even exploit city resources for food. On the contrary, ravens, traditionally more wilderness-bound, hold significant places in various cultures. For instance, in Norse mythology, the god Odin had two ravens named Huginn (thought) and Muninn (memory) that flew all over the world to bring him news. This symbolizes the bird’s association with wisdom and knowledge.


Distinguished members of the corvid family, ravens and crows showcase distinct characteristics despite their apparent similarities. Ravens, generally larger, display wedge-shaped tails and emit a throatier croak, while crows have fan-shaped tails and a clear caw. Both demonstrate remarkable intelligence, with ravens being seen as more advanced in certain cognitive abilities. Ravens frequently feature in myths and legends, whereas crows thrive seamlessly in urban environments. These differences, alongside their unique behaviors, diets, and cultural significance, underline the uniqueness of each bird.
