Answer: classical conditioning.
Explanation: The bird associates the pain or discomfort it experienced from the wasp sting with the sight of the wasp. In this scenario, the sight of the wasp serves as a stimulus triggering the bird's memory of the painful experience. This association leads the bird to avoid the wasp in the future, helping it to minimize the risk of being stung again. This type of associative learning, where an organism connects a particular stimulus with a specific outcome or response, is called classical conditioning.
