Now is a good time to remove blackbird roosting locations, such as cattails. Cattails serve as blackbird habitat, so it is in the sunflower producer’s best interest to get rid of as much as possible. The USDA can help with blackbird control. Visit: Blackbirds (sunflowernsa.com) for a map with phone numbers for USDA Wildlife Services personnel that can help North and South Dakota producers who have blackbird problems. They will respond to you during the damage season by providing loaner cannons and pyrotechnics. These offices will provide further assistance in an attempt to break up large roosts. Using a combination of cattail management, cannons, harassment, desiccants, and repellants can be even more effective when used together.
