The following paragraph was added to the Abstract:

Only carcasses judged to have been killed after the previous search should be included in 
the fatality data set submitted to this estimator software. This estimator already corrects 
for carcasses missed in previous searches, so carcasses judged to have been missed at least 
once should be considered “incidental” and not included in the fatality data set used to 
estimate fatality. Note: When observed carcass count is <5 (including 0 for species known 
to be at risk, but not observed), USGS Data Series 881 (http://pubs.usgs.gov/ds/0881/) is 
recommended for fatality estimation.
