Of course, being able to fly fast means nothing if your heart and lungs can't keep up. That's where the peregrine's aerobic fitness comes in. A bird gets its flight power from the metabolic activity in its muscle fibers. Red muscle fibers, designed to increase oxygen uptake, enable birds to efficiently metabolize energy and maintain prolonged flight, while white muscle fibers fatigue rather quickly.
Not only do peregrine falcons have ample red muscle fibers, but their large, strong hearts and highly efficient lungs and air sacs keep their muscles fueled with oxygen. Other birds can't even breathe when flying at speeds half as fast [source: Rizwan ]. Living atop high cliffs or buildings doesn't hurt their speed accumulation either, since objects naturally gain speed and lift from the upward rushing wind , as they descend.
If you dived from a building half a mile off the ground, you would probably achieve a pretty good clip as well. Whether you could grab a juicy pigeon at the end of that dive and fly back to your nest and snack on it is an entirely different story.

Peregrine Falcon Speed " ". During level flight, with motion generated by wing-beats alone, they can reach speeds between mph. This is one of the fastest known speeds for level flight with only a few species of duck, wader and pigeon known to reach similar speeds in comparable flight.
Most species of wild bird will have many different flying styles which they use in different situations. Birds will reach different speeds during these different flight styles. Migrating birds will often have a fast and steady rhythm, often using the wind to assist them. General flight will be more pedestrian whilst display flights and predator prey interactions can result in short sharp bursts of fast flight. It is during aerial pursuit where extremely fast speeds are reached by both predator and prey and this is where the peregrine is in a league of its own.
Birds of prey often use a controlled dive known as a stoop whilst hunting. This hunting technique is amongst the most spectacular of wildlife behaviour across the animal kingdom. The actual speed that a peregrine reaches in a stoop will be effected by the wind speed and duration of the dive, which will vary in every situation. Because of these variables there is not a confirmed top speed however it is thought that it is possible for a peregrine in ideal conditions to reach speeds of up to mph which is phenomenal.
The forces that the peregrine is exposed to during a stoop are mind boggling. What makes it even more fascinating is that at the end of the stoop, this unique raptor is still able to deliver a controlled blow and to carry away the unfortunate victim.

Mountain hare culls continue despite 'voluntary restraint" Coalition calls to introduce urgent safeguards for mountain hare populations. The peregrine falcon can do this because it has a one-way air flow into its lungs. The peregrine falcon has air sacs that keep its lungs inflated even when exhaling. The peregrine falcon also has a very strong heart that beats between and times per minute, allowing the oxygen to travel throughout the bird at high rates so it does not fatigue quickly.
The amazing speed of its heartbeat allows the peregrine falcon to flap its wings up to four times per second, contributing to its speed. Lorena Barba posted on December 12, at pm. It is really an amazing animal … great info about its powerful respiratory system and heart! Are the images taken from the sites you listed in your source list? I think it would be nice to add a caption.
