Fig. 3

Removing the negative recorded flight heights introduces biases in the distribution of the remaining flight heights. Left group of panels: in simulations, where the true flight height is known. Right group of panels: in the raptor case studies, where the corrected flight height is assumed to represent the true flight height. In all panels, the x-axis features the variance in the true (or corrected) flight height. The y-axis features the percentage bias in a mean flight height; b collision risk (proportion of time spent between 60 and 180 m above ground); c variance in flight height; and d skewness of the distribution of flight height. A percentage bias of + 10% means that the focal quantity is 10% larger after we remove the negative records
