The timescale is defined in terms of the foragers’ behavioral actions that vary in duration from about a few seconds to a minute. In the model a year is defined as 360 days, and a day is 12 hours or 720 minutes, where we focus on daylight time in a day. Thus foragers can complete many hundreds of behavioral actions in a day and learn from them. Energy expenditure (metabolism) occurs every minute. Digestion occurs every 100 minutes (DIGESTIONTIME). Foragers can live maximally for 20 years, but can die before that at any minute.
