The main purpose of this legislation is to create grant programs aimed at supporting the populations of migratory waterfowl in North America. It focuses on enhancing habitat conservation efforts by introducing specific tools and practices that can improve the success rates of nesting waterfowl. Key provisions of the legislation include the establishment of two main grant programs. The first is a hen house grant program, which will provide funding to eligible entities to build and maintain nesting structures known as "hen houses" in the prairie pothole region.
