Something I really like about Revontuli Coast is that it has a variety of waterfowl species available to hunt. I enjoy hunting waterfowl in this game, and I find it very fun to hunt waterfowl in places where you can hunt several different species at once. Waterfowl help to add more life to the skies and waterways of any map. In addition, having a variety of waterfowl species in any given location is very realistic to how it usually is in real life. There's many waterfowl species that would make for interesting additions to the game, and all of them would help to fill in existing maps with more species. Below are some that I'd really like to see in the game.
Northern Pintail (Layton Lake, New England Mountains, Mississippi Acres)
Gadwall (Layton Lake, Silver Ridge Peaks, and Mississippi Acres)
White-faced Whistling Duck (Vurhonga Savanna and Parque Fernando)
Egyptian Goose (Vurhonga Savanna)
Red Shoveler (Parque Fernando - suggested by MooseDragon247)
Snow Goose (Yukon Valley, Layton Lake)
Blue-Winged Teal (Silver Ridge Peaks, Mississippi Acres)
Paradise Shelduck (Te Awaroa)
Pacific Black Duck (Te Awaroa and Emerald Coast)
Wood Duck (Mississippi Acres. New England Mountains and Layton Lake)
American Black Duck (Mississippi Acres and New England Mountains)
Australian Shelduck (Emerald Coast)
I will talk more about these individual species in the forum thread, along with some more ideas regarding improvements to waterfowl in the game.
