Table 3.
A comparison of the distance traveled, speed, and time until being caught by the owl with/without shelter. The distance (m/min) describes the metric distance traveled by the rodent in each phase, comprising locomoting and non-locomoting periods. However, since the duration of phases was different for each rodent, data are "normalized" per minute of observation. This measure is not interchangeable with speed (m/sec) that refers only to the locomoting periods, and was calculated by dividing the distance traveled with the duration of traveling that distance (excluding all non-locomoting periods).
| Behavior | Phase of owl attack | Without shelter | With shelter |
| Distance traveled (m./min.) | Pre-appearance | 4.32 ± 1.6 | 4.16 ± 1.62 |
| Appearance | 1.80 ± 1.7 | 0.36 ± 0.68 | |
| Attack | 27.6 ± 6.0 | 52.3 ± 6.8 | |
| Post-attack | 15.04 ± 4.24 | 5.6 ± 2.07 | |
| Speed (m/sec) | Pre-appearance | 0.37 ± 0.46 | 0.54 ± 0.01 |
| Appearance | 0.82 ± 0.78 | 0.54 ± 0.05 | |
| Attack | 0.65 ± 0.93 | 0.83 ± 0.86 | |
| Post-attack | 0.96 ± 0.66 | 0.58 ± 0.02 | |
| Time until being caught (min) | 38.3 ± 6.8 | 83 ± 28.7 | |
