But people have actually tried to pin down a reasonable real-world estimate. Here\u2019s what has been deduced:\n\n---\n\n### \ud83d\udc26 Key Assumptions\n\n- We\u2019re talking about a European swallow (*Hirundo rustica*), since that\u2019s the one for which data is available.  \n- \u201cUnladen\u201d means no load (e.g. not carrying food or anything else).  \n- Flight is roughly level, not in a dive or against strong wind.  \n- \u201cAirspeed\u201d is the bird\u2019s speed through the air (not relative to the ground).\n\n---\n\n### \u2699\ufe0f Actual Estimates\n\nFrom several studies and estimates:\n\n- The average cruising airspeed of an unladen European swallow is about **11 meters per second**, which is roughly **24 miles per hour**. ([style.org](https://style.org/unladenswallow/?utm_source=openai))  \n- In one wind tunnel study, efficient wing flapping for these swallows (7\u20139 wingbeats per second) corresponded to flight speeds in the range **8\u201311 m/s**. ([style.org](https://style.org/unladenswallow/?utm_source=openai))\n\n---\n\nSo, putting it neatly:\n\n---\n\n**Answer:** ~11 m/s \u2248 **24 mph** (for a European swallow in level, unburdened flight).\n\n---\n\nIf you meant an *African swallow*, or flight under different conditions (e.g. carrying something, flying uphill, against wind), the speed might differ significantly \u2014 though data for those cases is much less clear. Want estimates for those too?"
