How Fast Can Ravens Fly?
[science] The Common Raven cruises at roughly 25–50 km/h in level flight and can reach approximately 80 km/h (50 mph) or more in a dive. Speed is not what distinguishes ravens as fliers — it is their aerial agility. Ravens are exceptional soaring birds and perform complex aerobatics during courtship and social displays that few birds of similar size can match.
Flight Speed: The Numbers
[science] Precise measurement of wild bird flight speed is methodologically difficult. Published figures for Common Ravens draw on radar tracking, wind-tunnel experiments, and field observations:1
- Cruise speed (level flight): approximately 25–50 km/h. The lower end represents relaxed travel; sustained powered flight runs closer to 40–50 km/h.
- Maximum speed (dive/powered descent): approximately 80 km/h or more. Figures above 100 km/h are sometimes cited but are not well-supported by systematic measurement.
- Soaring: in strong thermal conditions, ravens can maintain altitude at slow speeds of 15–25 km/h while expending minimal energy — soaring economy comparable to large raptors.
For comparison: Peregrine Falcons dive at 300+ km/h; Golden Eagles cruise at 50–70 km/h; American Crows cruise at around 40–50 km/h. Ravens are solidly fast but unremarkable among large birds in terms of straight-line speed.
What Ravens Are Famous For: Aerial Agility
[science] The most striking aspect of raven flight is not speed but manoeuvrability. Ravens are among the most aerobatically accomplished of large birds:1
- Courtship displays: breeding pairs perform complex aerial displays — soaring together, diving, tumbling, and rolling; pairs sometimes fly in tight synchrony with wingtips nearly touching.
- Play flight: young ravens and non-breeding flocks engage in extensive aerial play — barrel rolls, inverted flight, diving, chasing, and object-dropping. This is documented in both wild and captive birds.
- Wind riding: at cliff edges and mountain ridges, ravens exploit turbulent wind to perform prolonged aerial acrobatics — hovering, side-slipping, and tumbling in strong gusts.
- Mobbing and evasion: ravens regularly mob much larger raptors (eagles, buzzards) and can outmanoeuvre them in tight aerial combat due to superior agility at lower speeds.
Wing Shape and Flight Style
[science] The Common Raven's wings are long and broad — wingspan 115–150 cm — with deeply fingered primary feathers ("fingers") at the tip. This wing shape is adapted for:1
- Efficient soaring and gliding — broad wings generate high lift at low airspeeds.
- Powerful flapping flight — relatively long arm and hand allow high stroke amplitude.
- Manoeuvrability — the ability to adjust individual primary feathers gives fine control over lift distribution.
The characteristic wedge-shaped tail (a key identification feature) also contributes to aerial control, acting as a rudder in tight manoeuvres.

Frequently Asked Questions
What is a raven's top speed?
The Common Raven can reach speeds of approximately 80 km/h (50 mph) or more in a dive or powered descent — recorded in wind tunnel and field studies. In direct level flight, cruise speed is typically around 25–50 km/h, with higher speeds possible in short bursts or with a tailwind. These figures are consistent with other large corvids (rooks, crows), all of which are fast fliers for their size.
Are ravens fast fliers compared to other birds?
Ravens are fast and highly manoeuvrable for large birds — not in the class of falcons or swifts, but significantly faster and more agile than comparably sized raptors such as buzzards. Their long wings and relatively light build (for their size) produce efficient flapping flight. They are best known not for straight-line speed but for exceptional aerial agility — soaring, tumbling, and executing complex manoeuvres in strong winds, particularly during pair courtship displays.
Can ravens soar like eagles?
Yes. Ravens are capable and frequent thermal soarers. In areas with strong updrafts (mountain ridges, thermals over open ground), ravens soar for extended periods with minimal wingbeats. They exploit thermals and ridge lift in a manner similar to raptors, and are regularly observed soaring alongside vultures, eagles, and other large raptors. This soaring ability significantly extends their foraging range.
