Abstract

This report describes the Wader Energy Balance and Tidal Cycle Simulator WEBTICS. The model simulates food uptake of Oystercatchers (Haematopus ostralegus) and a distribution of the birds over exposed parts of tidal areas. The mudflats are described on input as a number of spots which have a position, height and surface area. Spots may contain prey items characterized by type, weight and density. The program simulates tidal cycles and calculates the fraction of time the average and ideal bird has to spend feeding in order to meet its energy requirements. These foraging intensities are combined into a stress index for the winter. Besides historical data on weather, prey distribution, tides and fishing, there are bird and prey parameters on foraging, prey growth and energy conversion. Model output files can be processed in a spreadsheet. Also bitmapped images and movies are produced.
