The Accuracy of Behavioural Data Collected by Visitors in a Zoo Environment: Can Visitors Collect Meaningful Data?

Figure 6

Results of bootstrapped PCA examining differences between ethogram data and different visitor segments. Black = ethogram data for group of otters, red = fun time families, green = sensualists, dark blue = social naturalists, light blue = expert birders, and pink = learn together families. No other visitor segments were included, since in total they contained <20 responses. Pairwise comparisons between social naturalists and sensualists also indicated no significant differences occurred between these categories. Cumulative proportion of variance explained by first 3 principal components = 0.997.
