Abstract : In response to the need for a modeling system for the northern pintail (anas acuta), we adapted the productivity component of the mallard model to northern pintails. We modified only the productivity component. Our specific objectives were to (1) compare the similarities and differences in breeding biology of northern pintails and mallards and identify aspects of northern pintails with inadequate data, (2) modify the productivity component of the mallard model as necessary for northern pintails, (3) conduct sensitivity analysis of the northern pintail productivity component, and (4) test the northern pintail model with available field data or expert opinion on the species breeding biology.
