What is the bite force of a cockatiel?

Cockatiels have a relatively weak bite force compared to other birds of prey. They typically use their beaks for cracking seeds and nuts, and for preening their feathers. The bite force of a cockatiel is estimated to be around 8 pounds per square inch (PSI), which is comparable to the bite force of a small parakeet. In comparison, the bite force of a large bird of prey like an eagle can exceed 500 PSI.
