Step 2: Place snakes in, on, or near bird feeder

Observe monkey behavior.
If monkeys are momentarily anxious about the snakes, they appear quickly to notice snakes are stationary ... and they ignore them.
A neighbor suggests I keep an eye out for monkeys and, when they appear, throw the snakes in a way that suggests to the monkeys the snakes are leaping towards them.
Okay. Tha'ts worth a try...I guess....
