Simplified Displacement model: Foraging Birds

This model, written in R, simulates the effects of offshore wind farms upon seabird foraging behaviour, and the ultimate consequences of this for adult and chick survival. The model has been designed for use with four specific proposed offshore wind farms in the Forth-Tay region, and for use with five specific species (guillemot, kittiwake, puffin, gannet and razorbill). Much of the code can be readily-applied to different species, wind farms and SPAs, but some will not fit. It was not designed to provide general code for modelling the effects of any wind farm in any geographical area.
