Goose

You are the goose in the picture, you alone and cold, you try to call for other gooses, but it doesnt work, you find some berries on the ground, but you dont know if you should eat them...... you decide you will keep walking, and you find a lake with a tiny cave, you can fit in it, and it all seems fine, there are also some blueberries not far across the lake. (you are any gender) what will you do next?
