DRC-1339 is a pesticide used to induce mortality in pest birds and is being used successfully to reduce bird damage to a variety of agricultural products. The feasibility of using live decoy traps baited with DRC-1339-treated rice baits is being evaluated for reducing blackbird damage to sunflower in North Dakota. To estimate the take associated with the use of the DRC-1339-treated rice baits, we developed a bioenergetics simulation to estimate bait consumption by red-winged blackbirds, yellow-headed blackbirds and common grackles. This simulation incorporates a module to estimate mortality based on the amount of treated bait eaten by individual birds and the species-specific dose response to DRC-1339. Simulation results for mixed gender populations of varying species composition are presented.
