"The peregrine falcon is the fastest animal on Earth. Faster than the cheetah or gazelle. Faster than the fastest dolphin or shark. Faster than any bird. In a dive it can break two hundred miles an hour."
"Jake was flapping his wings a little more than the rest of us. He had adopted a falcon morph. [...] Then, to my amazement, I saw something go zipping right past us, faster than either me or Tobias. It was Jake. His peregrine falcon's smaller wings made it harder for him to float on the thermals. But those same wings made him unbelievably fast in diving."
The peregrine falcon is the raptor morph used by Jake and James. This morph have been used in almost every book. This is smallest raptor morph out of all the Animorphs, although it is the fastest of all the bird morphs. James is the only Auxiliary Animorph to have and use this morph as well.
