Some bat and bird fatalities that are discovered and used in fatality rate estimation may not be related to wind-energy projects, even though the cause of death cannot be determined. Natural mortality and predation may be (i)___, but the level of this background mortality in project areas typically has (ii)___. However, background fatalities can be (iii) ____.
It's suggested that fatality might not be related to the project. This could be an indicator to evaluate other causes of mortality.
The first blank gets its clue from here, since the other possible reason for mortality "may be" natural, hence the word __responsible__.
Since the cause hasn't been determined , it can be assumed that the second blank would indicate the same.
The third blank is to state and contrast that although background fatalities in this case have been disregarded as an option, they possibility is actually __significant__.
