What is the fastest bird in the world?

In level flight, a peregrine falcon is nearly as fast as a pigeon, and has next to no chance of catching up with the latter in a hot pursuit, especially so, because of the pigeon's superior stamina and incredible aerial acrobatics. The needle-tailed swallow, at 169 km/hr (~105 mi/hr), is the fastest bird ever clocked in level flight.

Fastest in what regard? This question needs to be phrased better
