The desert is a complex ecosystem full of more life than most people expect! However, with the urbanization of the desert, certain animal populations are growing much more rapidly than others! Animals who feast on trash (such as ravens, possums, and squirrels) are growing quickly, while populations such as coyotes, tortoises, and hawks are dwindling. In this challenge, your task is to build a bird feeder to support the natural bird populations while protecting the food source from devious squirrels. Use traps and obstacles to deter the squirrels!
For our final design challenge, I challenge you to design your own experiment about something you have always wanted to learn! Go out and be curious!
