Watch for nests , the more the better .
When you find a spot that has a nest in roughly every tenth tree sit down under one that gives you a shot at as many of the nest trees as possible and become a statue . When the tree rats begin to come out again since they've forgotten you , start watching where they go and shoot when they concentrate in an area with lots of food if you're using a shotgun . Alternatively , you can pick them off one by one in the trees when they break cover , use a cylinder to modified choke .

If using a .22 follow above , but wait for them to calm down between shots .
