Prediction: Zebras are more cryptic than sympatric non-striped herbivore species. Draw a line for each of the three species studied (zebra, impala, and wildebeest) to indicate the probability of observing a pelt of the species over time from 7:10 pm to 8:00 pm. A probability of 1 on the y-axis indicates that the pelt was seen by all observers, and a probability of 0 indicates that the pelts were not visible. All pelts could be seen at 7:10 pm.
