A mockingbird drinking water from a bird bath illustrates both external and internal stimuli. The external stimulus is the presence of the bird bath, which provides a source of hydration in the environment. The internal stimulus is the bird's physiological need for water, driven by thirst and the need to maintain hydration. Together, these stimuli motivate the mockingbird to engage in the behavior of drinking.
