In short, yes. However, setting a silhouette spread that “works” is an art form. You must understand where the geese are likely to come from, how they might circle, and where they’ll want to land. Then you’ve got to make sure that you angle your decoys appropriately. You want them at slightly different angles so that as geese circle your spread they see the broadside of at least some decoys. However you don’t want them all facing random directions, either. It takes time in the field to master this. I’ve found that silhouette decoys are most effective in the early season or while hunting a feed. In these scenarios geese are generally flying lower so they can better see the silhouette decoys. Trafficking in high-flying migrators is usually easier with a spread of full-body decoys.
