Question

Quizplus · Accepted Answer

Tinbergen's experiment, which observed the relationship between the distance of a nest from broken eggs and the likelihood of eggs being taken, is an example of the evaluative approach in ethology. This approach involves assessing how different variables affect animal behavior, in this case, the impact of nest proximity to broken eggs on predation rates.
