Clustering HMM Events Identifies Sand Disturbance Events

(A) Example of clusters identified in a 60 s period. HMM transitions are color coded based on their cluster membership. Scale bar, 10 cm.

(B) Number of clusters identified per hour based on trial type. “Feeding only” are trials containing four females. “Build trial” contain four females and one male that builds a bower. The boxplot shows quartiles of the dataset while the whiskers show the rest of the distribution unless the point is an outlier.

(C) Before and after images (20 s) for eight example clusters. Left and middle panels show raw grayscale images. Right panel shows heatmap displaying pixel value differences in the left and middle frames. Yellow indicates large changes. Blue indicates no change. Scale bar, 1 cm.
