The Raptor Health V3 software allows wildlife managers to use a mathematical model and 17-sequential years of data to examine the localized population-scale impacts to raptors arising from one or more documented sources of mortality. The mathematical model within Raptor Health V3 is the closed-system Lefkovitch matrix, where a closed-system is defined to be no gains or losses to the population from dispersal. The Raptor Health V3 allows the user to input demographic parameters as well as time series data (counts of nesting pairs and counts of mortalities). Comparative demographic quantities produced by the Raptor Health V3 software include annual and bi-annual abundances of hatchlings, non-breeders, and breeders, growth rates (long-term, transient, cumulative, and stochastic), stable stage distributions, reproductive values, and dominant elasticities. The Raptor Health V3 software automatically generates Kruskal-Wallis statistical tests to compare differences in median growth rates, as well as quantifies the bias introduced to the results through the use of the algorithm as an estimator. Default values in Raptor Health V3 depict parameters of bald eagles and eagle nesting and mortality data collected by biologists at the New York State Department of Environmental Conservation.
