As soon as a pack of Tiger striped male raptors (Dr. Wu's 1st genetic variant) seeking new territory found their way to the northern interior of Isla Sorna, they encountered a second tribe of raptors. These raptors look radically different, being more bird-like with males sporting quills as a Mohawk and females being lighter in color.
Despite being somewhat less aggressive than the tiger striped variants these raptors will fight fiercely for their turf in the same way they never stopped hunting down the human intruders when they took their precious eggs.

Out of all the JP raptor designs the JPIII variants are my favorite....
