call operation and call behavior actions

[zyx]

Hello,

   What is the difference between call operation and call behavior actions? Someone can give me some examples?

[Geert Bellekens]

CallOperation action calls an operation, where a CallBehavior action will call a Behavior.
Operation is a Behavioral feature, not a Behavior.
From UML 2.3:

CallBehaviorAction is a call action that invokes a behavior directly rather than invoking a behavioral feature that, in turn,
results in the invocation of that behavior. The argument values of the action are available to the execution of the invoked
behavior. For synchronous calls the execution of the call behavior action waits until the execution of the invoked behavior
completes and a result is returned on its output pin. The action completes immediately without a result, if the call is
asynchronous.

Can be a call behavior action the call of an activity and a call operation the call of a method?
