I have a few more thoughts for my characters to get wild protein (from the U.S. Army Survival Manual):
All trails lead to water. Trails may be marked with animal droppings and trampled terrain.
Flocks of birds will circle over waterholes. Some birds fly to waterholes at dawn or sunset. Their flight at these times is generally fast and close to the ground. Bird tracks or chirping in the evening or early morning sometimes indicate that water is nearby.
At dusk, watch for birds going to roost. Some songbirds use the same flyway each day. (Use a net to catch) or locate tree, fix the net between poles and scare birds from other side of tree so they fly into net and become entangled.
Bird eggs — By carefully taking all but two or three eggs from the nest every few days, you will have a supply of fresh eggs for a week or two. Do not disturb the nest and do not remove all the eggs as the female will desert the nest. Do not kill the female during the nesting period if you want to keep your egg source.
Locate water hole or well-traveled trail and wait for game to come to you.
Move upwind or across wind, never down wind.
Move silently as possible in densely forested areas that limit your range of vision. Any noise (treading on dry twigs or leaves) will alert animals to your presence.
Deadfalls can be used to capture many types of game.
Snares could be used. An Ojibwe bird snare jerks a noose on a bird’s feet.
So, are you still hungry?
