| Quantity | Brief description | |
| Landscape Cells | ||
| Coordinates | Determine the position of the cell (cell center) in the model landscape. | |
| Size | The size of a cell (length (l); width (w)) represents a real-world dimension of 100 m x 100 m. | |
| Number | 10.201 cells, which corresponds to 102 km² | |
| Habitat quality (hq) |
The cells can take integer values for habitat quality (hq) between
0 and 3. hq = 0 represents unsuitable foraging habitat, e.g., forest.
hq = 3 represents the best foraging conditions, e.g., grassland with a
favorable mowing regime. |
|
| Red Kite | ||
| Coordinates | Determine the position of the Red Kite in the model landscape. | |
| Flight distance | Length of a straightforward flight: 100 m | |
| Circling radius | Radius of a soaring circle during foraging flight: 100 m | |
| Flight speed | Average speed of the Red Kite: 15 km/h (Bruderer and Boldt 2001) | |
| Flight height probability (pfh) | Probability that the raptor ranges at a height swathed by a WT rotor; based on empirical flight height distribution | |
| Flight through rotor probability (prsa) | Probability that the raptor flies through the rotor-swept area and does not pass through. | |
|
Physical collision probability (pBAND) |
Probability of a bird being hit by a rotor blade if passing orthogonally to rotor-swept area. |
|
| Collision avoidance probability (pav) | The likelihood of a Red Kite actively avoiding collision with a WT. | |
| Probability of circling and flying forward (pf) | Controls flight behavior during the search flight (see Fig. 2). The variable pf indicates the probability of flying forward. The probability of performing a left respectively a right full circle is (1-pf)/2. | |
| Maximum residence time on cell (T) |
Determines how long the agent occupies the same cell, given that all
neighboring cells are of lower habitat quality. |
|
| Wind turbine | ||
| Coordinates | Determine the position of the WT in the model landscape. | |
| Hub height (hh) | Height of the rotor center: 78 m | |
| Rotor blade length (r) | Half of the rotor diameter: ½ of 82 m = 41 m | |
