Become a citizen scientist by creating your own mammal feeder! A citizen scientist is any person who helps participate in scientific research, like gathering their own observations, to send to researchers trying to answer

Materials:
- Scissors
- 2 plastic bottles of similar size
- Tape
- Stick
- String
Instructions:
- Cut the top off of the two bottles.
- Use one of the bottoms of the bottles to make a bottom for the feeder. Cut two windows opposite of one another for the animals to access the food.
- Poke a small hole directly under the feeder windows to slide the perch stick through, the place the perch stick in the holes.
- Tape the two bottle tops together, with one top facing up and the other facing down, as seen in the diagram.
- Tape the upside-down bottle top to the bottom piece with the windows and perch stick.
- Make a hole in a bottle cap and run a string through to hang the feeder.
- Screw on the bottle top and hang for your backyard squirrels to enjoy!
