Yes, that is a common name for the peregrine.

Your peregrine thoughts have illumined my mind.The Peregrine Falcon (Falco peregrinus) is also known as the Duck Hawk, in America.The peregrine may reach a speed of 200 miles per hour, in a dive.
There is no such word as perefin. A Peregrine falcon is a bird of prey, however, and is known as the duck hawk in North American countries.

The Peregrine Falcon is much faster. He is a predator, and can be taught to hunt for and return to a human trainer .
The peregrine falcon feeds on birds like pigeons, grouse, pheasants and waterfowl. Especially fond of ducks, hence the old name, "duck hawk".
That is not entirely true. When you measure the flight speed of the birds you have to account wind, height and temperature in order to get true speed in still air. Speeds in range of 100mp/h for merganser or a spine tailed swift are highly unrealistic for low level flight propelled solely on muscle power and are definitely helped by relatively strong winds. It was concluded in one long Peregrine Falcon study that lasted almost 48 years that no pray specie that Peregrine pray upon was faster in level flight. To substantiate that, here is one link where you can see falcons hunting ducks. They dominate the air with ease! http://www.youtube.com/watch?v=G-FZdIrKyBk&feature=related There are no Peregrine Falcons in video, but it is known fact that the Peregrine is faster than Prairie Falcon both in level flight and in a stoop.

The world's fastest flying bird (in level flight) is spine-tailed swift recorded at 170 km/hr. Though some racing pigeons is also said to have been clocked at similar speeds or even more.The peregrine falcon (Falco peregrinus) is the fastest living creature, reaching speeds of at least 124 mph and possibly as much as 168 mph when swooping from great heights during territorial displays or while catching pry birds in midair.Peregrine FalconWhen the Peregrine Falcon spots prey it goes into a controlled dive easily reaching speed of 200 MPH or 320 KM/H.The fastest speed the Peregrine Falcon reached ever recorded was an amazing 242.3 MPH or 390 KM/H.It is also the fastest animal on the planet.
On the short burst the Peregrine Falcon has the fastest speed during its power dive. If you mean 'travel' in a more distance producing sense then certain duck and mergansers have been know to keep up with aircraft during take-off.
