The relationship between margin of error in tick burden estimates and number of locations sampled. Margin of error was averaged over 1000 data sets simulated under scenarios that varied in mean tick burden and the degree of variation in mean tick burden at the location, brood and individual chick levels. The grey line shows the target margin of error of ± 25%.
