Table 1. Ethogram and activity budget by housing condition and time of day.
Values rounded to three decimal places, anything below three decimal places are rounded to 0.000. Unobserved behaviors are noted as such. Mean difference was calculated by subtracting Complex housing value from Standard housing value.
