Distribution of echo incidence points on obstacle walls during the first and last flight. a The histogram shows the probability of echo incidence points being located at various distances to the inner edge of the obstacle (acrylic walls) during the first and last flight. b Box plots summarize data on the distances between echo incidence points and the inner edge within the inner half of obstacle walls for the first and last flight, while the black whisher plots represent model-related means (black circle) and associated 95% confidence intervals. These results are based on a model that fit the data well (based on residual plots) and that explained significantly more variance than its null model (χ2 = 12.95, df = 1, p < 0.001). In addition, the effect of the spatial-learning-factor in the model was found to be significant (χ2type-II-Wald = 13.0, df = 1, p < 0.001)
