Table 3. Notation of parameters, variables and indices.

Name	Description
Parameters
P	carcass detection probability: probability that an animal that has been killed by a rotor blade is found by a searcher
A	proportion of carcasses lying in the search area: dependent on the spatial distribution of the carcasses and the search area
S	daily carcass persistence probability: probability that a carcass remains in the area for 24 hours
F	searcher efficiency: probability that a carcass lying in the search area is found by the searcher during one search
Indices
I	turbine
T	day
R	simulation
Variables
cit	number of carcasses found at turbine i at day t, “count”
Nit	number of collisions per day, collision rate
Ni.	total number of collisions at turbine i
Ait	acoustic activity measures, total number of bat calls during night t at turbine i
Wit	median over night t at turbine i of the mean wind speed during 10 min intervals
zAit, zWit	standardized (to a mean of zero and a standard deviation of one) acoustic activity and wind speed variables
