As was shown in a recent thread, there is a lot of confusion as to using electronic calls when hunting migratory birds.
Regardless of it is the spring or fall season, or what decoys are or are not present, electronic Snow Goose calls are legal.
From "Ask F&W What is the Law" sticky thread....

Question: With the change to allow different waterfowl decoys in your spread while using an electronic snow goose call, does this mean that if other waterfowl (ducks, Canadas, etc.) come into your spread, you can shoot them while using these calls.
Answer: In short, yes. You may shoot any species you are legally able to hunt while using an electronic snow goose call. However, be sure you are only playing snow goose ‘music’. Some tracks that are commercially available do have ducks, white-fronted geese, and other sounds playing in the background. Buyer beware.
