Swallow and sparrow are different birds. Seems that Sparrow is also named "Northern European sparrow"
If you really mean Sparrow, do you mean Passer domesticus or Passer montanus ?
If you meant Swallow then:
- Swallow/Speed : 50 – 65 km/h
- The airspeed velocity of a (European) unladen swallow is about 39 km/h
