Estimates of death rate per meal <i>C</i> of oriental white-backed vultures, the annual rate of decline of the vulture population and the percentage of excess vulture mortality that is attributable to diclofenac poisoning <i>E</i>, based upon concentrations of diclofenac in liver samples taken from

A significance test of the difference between the rate of population decline estimated from diclofenac surveys and road transect counts of vultures and the level of support (% of bootstrap/Monte Carlo replicates) for diclofenac poisoning being the main cause (>50% of excess mortality) or the sole cause (100% of excess mortality) of the vulture decline are also shown. Results are given for calculations that used a dose-response model including and excluding an outlying datum (Gb11), for two plausible values of the interval between meals F (days) and for the bounds of the likely range of pre-decline annual adult survival probability S0.
