Abstract: Abstract Optimal foragng theory has been an area of increasing interest (for a review see Pyke 1984, Stephens & Krebs 1986). Time budget parameters are of vital interest when modelling optimal foraging. In particular animals that show behavioral changes in foraging over short time intervals (ie. a day) are likely to show small scale variation in the time budget during the day. Especially for large, long lived animals, some difficulties are involved when estimating these kind of parameters (see also Engen & Stenseth 1987). Partly, the difficulties are caused by sampling problems when estimating time intervals as for example activity periods, and partly the cost of sampling data restricts the number of observations.
